00:14:58.04 So, how... and I just want to point out that this problem is not unique to phalloides. 00:06:30.14 And that's really the point of reverse ecology. 00:15:55.13 And it's almost certainly true that the fungi that we once worked with no longer exist in 00:19:27.17 Well, one of the things that I did was go back to these old specimens, get DNA, 00:15:36.22 the genus Amanita, typified here by this very beautiful Amanita muscaria. 00:25:28.07 These seem... genes that are responsible for oxidative metabolism seem to be at play in 00:26:57.16 But when we did this work we couldn't do it. The death cap (Amanita phalloides) has an olive-brown cap and the archetypal cup and ring. 00:01:50.04 And, by the way, the word mycorrhizal sounds complicated, but it's not. 00:09:16.22 Well, interestingly, it's true now and it's been true for a very long time that there 00:06:47.09 It's a way for plants to get access to scarce resources when they're living in habitats (Agaricales, Basidiomycota) is a cosmopolitan genus comprising about 500 described and accepted species [1–3].This genus is one of the most known fungal genera because it comprises both deadly poisonous species, e.g., A. phalloides (Fr. 00:25:53.11 And that the data support one hypothesis over the other -- the independent amplification 00:23:49.01 the different nodes -- you can see that it's node 3 and node 5... follow them down and 00:08:56.08 but just to acknowledge that took a lot of time for her to go all across Southeast Asia and North America, 00:21:39.00 where there are fresh strawberries. 00:19:56.02 So, in previous slides, in this slide, and in future slides, green always marks the symbiotic fungi 00:22:50.01 How did that work in evolution? Although old Deathcap fruitbodies have an unpleasant smell, young ones at the button stage are virtually odourless. 00:26:00.04 of genome size in two lineages. 00:30:20.16 along the way with this story. 00:11:42.18 And that's... that's... not the modern view, it's what we... it's... this is the fact... 00:04:59.22 and function. 00:17:34.23 But, I can tell you that, as of this moment, specimens with a European morphology are certainly... 00:21:48.23 And the arrows mark points of... mark historical specimens dating from the 1930s and 1940s, 00:20:21.22 large genomes and one that does not have a large genome. 00:19:44.20 And the experiment is quite dramatic, as it often is when you do this kind of experiment. 00:11:59.10 They're not just diseases. Its potency is not reduced by either freezing or cooking the fungi before eating them. 00:05:32.12 convergent interactions, Amanita phalloides in various stages of growth Photo by Justin Pierce. 00:28:18.04 And this suggests that people were in states like Illinois, for example, and collecting 00:15:39.23 Well, this is one thing that can happen to the biodiversity of things we don't have names for. 00:03:58.20 and the more green the county is the more Irish-Americans live there. This largish fungus, known infamously and justifiably as the Deathcap, accounts for more than 90% of fungus-related poisoning deaths in 00:16:59.15 What you're looking are lots of different Amanita species. 00:11:06.03 Was it introduced to Europe? 00:23:13.20 So, if you want to think about the Earth and biogeochemical cycles and the... the big picture 00:02:35.17 they're enormously diverse. The Death Cap - Amanita phalloides (MNH OG) Stamp. 00:13:10.04 So, these associations these arbuscular mycorrhizal fungi, are common with plants like grasses, 00:27:08.12 cohorent... coherent, coordinated behavior, these pulsatile contractions that move $1.35. 00:11:09.10 -- again, not exactly the same species, but very closely related species -- 00:02:21.13 Fungi eat dead things. 00:07:53.03 It's fascinating for that reason, but it's also fascinating because there was a... Initially the gills are pure white, but they turn cream, sometimes with a slight pinkish tinge, as the fruit 00:12:21.10 Here's the field in North Carolina where I used to do quite a lot of work. 00:23:16.14 two different ectomycorrhizal species. 00:15:45.15 This is actually a picture of my field site, which, shortly after I stopped working there, 00:20:33.21 But there really isn't a clear pattern, three versus three. 00:13:47.22 And we found lots of different kinds of species in this field, including many that were 00:09:56.03 But, each is very distinct from the communities that you can find in the surrounding soil 00:09:00.18 The word mycorrhizal just means fungus/root myco/rhizal. 00:11:47.15 And it has this green coloring on it and this very characteristic shape. 00:29:43.00 First, like plants and pathogens, mutualist fungi are invading novel ranges, often in 00:01:33.10 In this case, the... the network has been brought above ground by growing it in a petri dish. 00:00:18.04 So, it's a challenge to try to teach about fungi in a short talk, because there's a lot to say. 00:27:37.05 I think a commonly held idea is that spores are passively dispersed, just depending on 00:01:30.10 And they're bringing those nutrients back to the plant in exchange for carbon compounds. 00:21:28.01 "European morphology" in quotation marks, it is the European phalloides. 00:24:03.07 two points on the phylogeny that have the most duplications, again supporting the 00:24:41.02 So, for example, polypyramis shares 27 gene families uniquely with thiersii. and occasionally with softwoods. 00:04:13.10 And some years later, another group discovered that actually some of those sequences that 00:04:38.04 And so, for the moment, they still fall within the study of people who call themselves mycologists. 00:27:30.08 in Texas and that it grows in suburban lawns in the Midwest. 00:27:00.09 is a relatively easier evolutionary dynamic Indeed, the familiar mushroom is a reproductive structure used by many types of fungi. 00:20:16.13 And what you can see right away is that there are two ectomycorrhizal species with 00:29:16.08 I've walked in these woods... actually, not the woods. 00:27:58.01 So, it's hard to know whether we should call this an invasive species that's from 00:10:40.04 Is Herb Saylor right? In the meantime, 'never eat a Amanita' seems to be a pretty good maxim, and especially when applied to white members of the Amanita genus. 00:09:25.15 she sampled. 00:07:33.01 in that park, there's this species, the death cap, growing. 00:24:51.18 So, he looked at this pathway. From Russian Federation. 00:26:53.09 Although, actually, we just got one in the last couple of months, so stay tuned -- 00:12:47.04 This is an arbuscule of an arbuscular mycorrhizal fungus. 00:03:25.01 Or are they not genetically diverse? 00:27:49.13 We don't know where this fungus is native. 00:16:54.15 And he... it's another slide that took many years to put together... he generated this 00:06:00.14 That's a specific story. do not have volvae; also, the gills of immature Amanita Terms of use - Privacy policy - Disable cookies - External links policy. Last one. 00:04:21.05 I had generated had nothing to do with the fungus that I was interested in. 00:26:32.14 Well, resem... remember that one of the things that I showed you was that this interaction, 00:23:50.07 Maybe actually it has... maybe it can form these associations with roots, but maybe 00:19:35.06 six genomes, three ectomycorrhizal genomes 00:22:39.04 non-native species of ectomycorrhizal fungi we know exist in that country. 00:04:05.18 or it's a plant, or it's a fish. 00:19:39.09 bigger -- again, it's the big plant versus the little plant -- than when they're grown 00:22:37.00 data as well. 00:04:02.09 diagnostic morphology. MCB-1052331. 00:09:09.01 inside those pitchers, and then use the technique called ordination to put every sample Several toxins have been isolated from this poisonous toadstool, but the constituent that damages the liver and kidneys of anyone who eats the Deathcap is known as α-amanitin. 00:01:55.05 It simply means fungus/myco, rhizal/root. 00:03:51.15 So, you can see that it has... just... it hasn't happened just once in nature. 00:06:41.02 how its genes are patterned across the Earth, you can discover something about its niche. 00:17:39.03 These are called big plant, little plant experiments. 00:09:37.23 And so this is one way we try to stay ahead of diseases, is breeding crops that... 00:23:39.20 And, in fact, if you do a profile of the duplication of the gene families -- here, we've numbered poisoners down the centuries, and even nowadays it is still the cause of Its use was known among almost all of the Uralic-speaking peoples of western Siberia and the Paleosiberian-speaking peoples of the Russian Far East. 00:07:29.23 And it's... it's essentially the price of food, as measured by... by looking at a particular 00:14:39.23 So, the relocated Nepenthes do seem to acquire Sarracenia-like communities when acidity levels 00:21:11.14 Fungi, like this one, come along and just turn them to mush. In 2003 an adult man in Victoria ate what he thought were puffballs growing in his front yard. 00:14:27.01 of shape, a pitcher shape, cluster somewhat away from the Sarracenia and the Nepenthes. 00:06:46.03 And they're eaten. 00:20:01.22 That doesn't really solve the problem of the literature. 00:20:47.23 Fungi are decomposers. The Deathcap occurs throughout Britain and Ireland and can also be found in other mainland European countries, where it occurs most commonly at low altitudes. 00:15:05.11 And we are thinking about how to understand what the functions are of these 00:15:00.18 And some of these forms are very familiar, the classic mushroom for example. The word fungus comes from the Latin word for mushrooms. 00:12:39.16 you know, the lack of easily available things to read, no internet... it seems obvious to 00:22:07.12 And this is an image of those different kinds of channels. 00:04:09.09 But it... the answers I was getting at the time were incomplete. 00:29:07.13 early on who said to me and to others, this thing is moving its range. Amanita phalloides / æ m ə ˈ n aɪ t ə f ə ˈ l ɔɪ d iː z /, commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita.Widely distributed across Europe, A. phalloides forms ectomycorrhizas with various broadleaved trees. 00:26:16.04 genomes, and that's what we did. This fungus usually mixed with mushrooms (Agaricus). 00:00:56.09 of any organism. brownish-cream veil fragments on the cap, and a volval rim around 00:09:12.12 How do you control fungal diseases? 00:06:44.03 Insects fall inside the pitcher. 00:03:06.01 And what you can't see, but is surely true, is there are a lot of other kinds of fungi alba Costantin & L.M. 00:02:33.08 This is the mycorrhizal symbiosis. 00:25:54.03 Why... why is that? 00:23:24.10 of specimens and sequencing of specimens, and trying to understand patterns of genetic 00:00:54.18 But fungi don't only cause disease. 00:18:33.12 And it's either going with one species of fungus or another species of fungus. 00:16:48.21 If the last blue whale choked to death on the last panda, it would be disastrous and sad 00:11:20.04 And that means that any antifungal that's developed is quite likely also to be an antihuman, 00:02:43.04 How do we do biology on these kinds of organisms? 00:05:40.02 we were thinking about when we used these words. 00:17:21.16 So, this is the backdrop against which I collected my mushroom about ten years ago and said, Amanita phalloides (Vaill. larroquei F.Massart & Beauvais ex F.Massart, 2004 Amanita phalloides var. 00:20:00.00 were not phalloides. 00:15:13.01 With a very different system, then, we started to think about why it might be that you have 00:29:19.02 I've walked these lawns for decades and, for the first time, I'm seeing this species 00:11:55.03 So, fungi are diseases, but they do a lot else in our world as well. 00:13:19.21 the diversity, in this case, of bacteria inside that pitcher. 00:09:35.11 So, we know, or knew, very little about the kinds of dynamics associated with mycorrhizal fungi 00:13:50.04 Here's a specimen, a dried mushroom that has this fantastic photograph that goes with it. 00:22:28.13 each of the ectomycorrhizal species, 00:12:09.00 They provide benefits to plants, to animals -- we won't talk about that so much today -- 00:03:51.06 This is one of my favorite examples and it's a historical one. 00:16:41.19 read it with you. 00:22:40.16 What about the amplification of these two... of... in genome size of these two ectomycorrhizal species? 00:18:30.15 So, to solve this problem, I had to take a variety of different approaches. 00:16:55.20 But if we accidentally poisoned the last two species of ammonia oxidizers," or some other 00:03:18.06 So, let's talk about what fungi do in the world. 00:24:08.01 for your compost bin. 00:18:36.03 One approach I took was to use genes to tell me whether a particular specimen was or 00:16:27.11 I had become fascinated by the problem of invasion biology of mycorrhizal fungi 00:16:05.07 When you turn a... a grassland or an old field into a lawn, generally you fertilize that lawn. 00:25:05.06 fallen off the tree. Colours vary with location and even from sample to sample, but the 00:02:21.13 They find scarce resources like nitrogen. 00:08:05.14 It's also true that, at those moments when food is very expensive, there is a correlation 00:25:42.12 And if you look at phalloides, it becomes very clear that it does not have the genes 00:00:12.02 University of Wisconsin Madison. 00:05:53.03 So, it does... we know where on the Earth we can find this particular kind of sequence 00:04:22.12 labeled as fungi. 00:05:39.22 It shaped how Ireland is... Ireland has still not recovered demographically from the potato blight. 00:17:04.00 And it could be happening now and we wouldn't even know," 00:20:11.04 So, these are just some basic genome statistics. 00:06:04.10 So, it comes from soils, from roots, that was also true of the study that I did. 00:04:58.04 Eventually, we understood that this new thing that we were seeing in the tree of life was 00:10:52.00 The outer ring, the brown, are organisms that we find in bog water or soil. Animal feeding behaviour has generally been Amanita phalloides is quite a common species in most parts of Britain and Ireland. 00:20:43.01 that seems pretty cryptic, it seems like it's a thing that not very many people know about. 00:26:32.10 decomposition, but a whole suite -- dozens and dozens of genes that are involved in decomposition. Paul M. Kirk, Paul F. Cannon, David W. Minter and J. 00:01:01.14 Fungi are also mutualists. 00:24:10.10 second idea of an independent amplification of genome size in the two places. 00:17:18.11 Well, with arbuscular mycorrhizal fungi, their role in nature does intrinsically, immediately 00:23:01.23 in genome size. Edited by Knudsen, H. & Vesterholt, J. ISBN 9788798396130. 00:14:37.22 a pH. 00:01:45.13 Plants are growing with fungi; they're engaging in these mycorrhizal symbioses. These turned out to have been undeveloped “buttons” of Amanita phalloides; a site visit later revealed several mature death cap mushrooms at this location under a mature English oak tree. 00:18:00.12 will give us some insights as to what's going on. 00:06:21.20 They both form pitchers which house pools of water inside them. 00:07:37.02 So, the death cap is interesting because it kills you, and it's always fascinating to 00:16:23.21 what it is. 00:11:46.20 this is what we know now. 00:15:56.12 If I cut those root tips, I would find Hartig nets. 00:11:31.01 And in the soil you found a beluga whale. 00:14:11.02 But here they are and they're beautiful. Your email address will not be published. 00:02:24.03 tropical fish, except they're tiny and they live in soil and they don't swim. 00:29:22.10 and I can see it's thiersii. 00:25:57.12 All of that... why is there all that movement? 00:23:07.14 That's hypothesis 1. 00:24:09.12 The fungi come and they establish and they grow and they tear apart all that dead stuff. 00:15:32.04 And I'm gonna talk to you now about a genus that's near and dear to my work, and that's 00:15:39.22 So, when you collect a mushroom and you're trying to figure out whether it's the thing 00:29:35.13 And if you have any questions about human diseases or sick buildings, 00:05:17.11 It's a new way to think about something that I think we've known about for a long time, 00:06:34.04 You can't grow it in a manipulative experiment but, through understanding, for example, 00:08:31.01 food insecurity, there's also political instability. 00:13:47.03 If it's a triangle, that means the pH in that microcosm was less than 4. 00:22:53.07 It's not unique. 00:04:18.19 of Australian Nothofagus trees and Australian truffles. 00:02:58.20 It's often, for example, in books of fairytales, you'll see it. Amanita bivolvata is a botanical synonym. 00:22:32.00 had data for it. 00:17:57.17 and the genetics of the ectomycorrhizal symbiosis here, Mycorhizal with hardwood trees, especially oaks, 00:13:00.15 And we replicated this across the bog. 00:25:07.07 will never travel down to your foot. 00:26:38.07 this ectomycorrhizal interaction, has evolved repeatedly, over and over again, which is... 00:03:44.02 And there just simply wasn't a lot of information. 00:17:54.00 are marking various sites where, during one of our collecting trips, we were trying to 00:09:20.18 are two... there are two mechanisms that growers use to control disease. 00:27:11.08 And maybe that's why these things have evolved repeatedly. 00:00:29.11 what the fungi do in our world. 00:07:15.05 And this is a story that started when I lived in California and I collected some mushrooms, 00:20:43.22 that distinguishes the three symbiotic ectomycorrhizal species 00:17:29.08 So, I'm gonna walk you through a series of experiments that have been duplicated, think, 00:09:16.20 And the interpretation is that if two points are very close together they're closely related. There is, however, an all-white form of Amanita phalloides that 00:10:21.16 But there are complications with these kinds of ideas. 00:01:55.01 What you're looking at here is a photograph, on this book cover, of seedlings of plants, 00:01:04.05 What you're looking at in this image is seedlings of pine and you can see the roots of those 00:08:08.01 So, to test the idea of... so, they have a... so, these pitchers are convergently evolved -- 00:24:48.04 And if you look to see where the three ectomycorrhizal species 00:06:18.04 But they look remarkably alike, as you can see in these drawings. 00:06:53.19 And that's clearly... clearly a very... a very important impact that diseases have on humans. 00:20:17.04 So instead, you have to take a different approach. 00:11:53.10 of organisms that you find in those different places. 00:29:39.04 So, the takeaways from this talk are really two. 00:23:38.06 ectomycorrhizal symbiosis. 00:29:03.16 And if you'd like to know more, these are resources that you could go to on the web 00:19:20.01 How do you get to being a symbiont? 00:13:04.04 This is really what I considered to be the first major work of American mycology. 00:25:48.00 that would enable it to be a decomposer. 00:11:40.00 in terms of the phylogenetic relatedness. 00:09:56.01 And diseases usually spread with... with propagules called spores. 00:17:34.21 So, it lends itself, in a really nice way, to understanding the genetics of the ectomycorrhizal 00:24:28.02 their different roles in the environment. Not distinctive when young, but old 00:02:33.00 But you can see a fish if you go scuba diving in the tropics. 00:20:34.22 Just like a population of humans living in Finland might have a unique set of genetic variants The poisonous fungus is usually found during autumn but wet weather has prompted its early arrival in 2015. 00:08:20.08 the red lines mark how many violent protests are happening in a particular place 00:12:29.18 We also added sterile glass tubes that either had or did not have insect prey, in this case 00:21:08.19 and analyzing them with our bioinformatics pipelines. 00:10:34.23 There are all kinds of biases that might be a part of this work. 00:21:57.21 So, carbon is an element that's moved through the planet in... in... through different channels, 00:08:25.23 And it's fairly striking and perhaps not surprising that, when food is expensive and there's 00:19:42.03 that are free-living. 00:25:58.22 just by looking at sequences of genes, presence or absence of genes, I've learned something 00:15:35.04 He was one of the first people who put a system to our names of fungi. 00:29:33.13 This uhh... genera of fungi. 00:00:46.17 their PhD and postdoctoral research, respectively. 00:29:03.11 Because, aga... like Herb Saylor with the phalloides story, there were people 00:30:30.21 And these are all the people who very gracefully offered up their stories, in heaps of emails 00:09:43.02 that simply can't be infected. 00:00:15.03 And today I'm going to talk to you about fungi. Updates on exciting iBiology projects in development. 00:00:32.04 that we otherwise have a hard time understanding. 00:11:18.00 So, it's as if you found... in Nepenthes and Sarracenia, in one you found a chimpanzee Swanson, E. Gan, N. Bubandt. 00:03:50.01 a mycorrhizal symbiosis. 00:04:00.23 in that sequence, the public database spits back at you an answer -- it's a chimpanzee, 00:14:55.21 It was all a giant muddle, essentially. 00:12:07.03 So, if I click back and forth between these two images, I want you to kind of codify It is believed that it causes 95% smrtih outcome in mushroom poisoning. 00:26:00.01 Well, this is again a fungus-like organism, not a true fungi, but it's become a bit notorious 00:13:24.03 So, in red circles are the Nepenthes from Southeast Asia, the data that I showed you before. 00:08:25.22 inside Nepenthes versus the ecosystems that form in Sarracenia in North America? 00:14:44.21 Maybe it's native? 00:01:35.05 It's a classic exchange of benefits or resources, and the truth is, as you walk around in the world, Amanita verna var. A. phalloides (alternatively Agaricus phalloides, Agaricus bulbosus, or Amanita bulbosa), a basidiomycete, is one of the deadliest mushrooms in the world, and accounts for about 50% of all cases of mushroom poisoning on its own. 00:06:12.11 And if you're interested, this is a group that's now discussed as the archaerhizomycetes. 00:07:26.21 In fact, whole communities of bacteria and fungi and other kinds of basal eukaryotes 00:19:55.18 There's not a single origin to this kind of mutualism. 00:10:49.04 or surrounding bog water or soil. 00:19:46.20 The morphology didn't match and it turns out that there's a reason for that. 00:15:48.02 to settle the case". 00:08:03.08 like wheat. 00:18:50.20 offer an equivalent benefit. 00:27:32.13 When it comes to dispersal... 00:15:29.05 Fries, who was in a sense the mycological Lin... 00:07:47.13 Nothing by the way, you can touch it it's no problem. 00:00:45.21 is that there is a fungal disease of amphibians that's spreading through the world, 00:16:57.20 is found in the United States... authoritative opinions can be cited for the alternative views."
