How Plants Fight Disease

Automatic TRANSCRIPT

The microbial world and to my listeners. Probably the most. Famous interactions are the mike arousal associations or maybe some of the bacteria that form in the knowledgeable lls and help fix nitrogen but there is a wide spectrum. Oftentimes pathogenic interactions between plants and microbes. So what made you go sort of the pathogenic or at least like disease route with them. Tie back to where. I kind of realized that when they get sick they actually died and when they died. Then there's less moves go around the world that means prices will go up and that means people that are less fortunate probably not gonna be able to bottles plants or bottles products eventually and it just kind of tie back to where i wanted to katina help others. So it's still tana original passionate helping others. i'm just doing it at a bigger in a much broader implant. That's really cool. Yeah and thinking about sort of all of the threats we face with climate change and just habitat loss. And you know everything. We're going through society right now. Understanding how plants are going to either survive. Stressed out or die has huge impacts across the board whether you're an ecologist worried about conservation or the idea of like food security and just getting people with their right to have access to good food. All of this can tie back to plants on some level and really that stressor. It's not like they're all just gonna fry because it's too hot out a lotta times. They're getting stressed and dealing with a lot of other stuff. Which is where your research. A lot of your research comes in so you mentioned They have similar ways of fighting disease but not exactly because their plants. They're not animals and so let's think about how plants interact with microbes. Do plants have and immune system on a broad spectrum. Is it anything akin to like what we have so. Am i get some backlash for this. But i go hanley. Okay always been. That's always been this debate whether plants have immune system and i some people like to use it I don't like it at all. Okay just put a bad. That they don't have white blood cells. They don't have antibodies. They don't have this like adaptive immunity like we do. I don't really consider that as amused. Glance what. I like to call that. Halfway is planning needs. So they have immunity something. They have components that they made themselves the fan against grows okay but they don't really have that adaptive like components that you will call an immune system so i think If we want to go down with differences so plants and humans One thing they do have in common is they both. Have these receptor like proteins or something that helps them to chat micros. Okay so the way. That dataset microsoft similar invoke lanson mammals. The difference with the malians is Wadis components that water similar allow these receptors are intracellular and Mammals while plans are intracellular. So they stay outside of plant sale and they perceive those microbial related is cool now thinking about all of the different sorts of microbes that can cause an issue for a plan. I mean there's bacteria viruses fungi. I mean does the response. Sort of differ depending on. What's coming in or is it. Just kind of all lumped in and sort of the mechanisms of detection might have some variants. Or where does it begin depending on. What kind of micro talking about here. And i think that's what kind of Fascinate me about this. Feel is like Depending on what the pathogen is or what motive of affection is doing like you get a totally different defense mechanism front of land. So let's say bacteria for example That's half jello. So that receptor. Or the estrogen receptor of plants dakin that said a certain points of jello or from some better and when they detect that part of on they send like a sidney lynne halfway or finland was biased. Light through the plant sales down the activate a defense response or to defend ourselves against the pathogens. So that's like the plant site first response to it But bacteria what they have evolved to do as they had these small proteins or relatively small proteins call factors and these factors what they can do. They can kind of turn off that plants. Though plans they try and go for gel on. They'll try to turn the pathway on and a bacterial cells secrete of that. There's an plant sale and l. Shut off that halfway. Jeez yeah no and that allows the bacteria to continue to invade the vet the planned sale with some cases plant sales. They of all some of these Resistant genes components which are located intra zillur so when arafat their turns off there signaling pathways. You have somebody's resistant. Genes that can detect those offenders and entered on this really robust defense response to kind of just get rid of packaging and so it's just this back and forth on race between planning micros is kinda fascinated with and i'm so glad you said the arms race analogy because that's all i was thinking of is like it's like tit for tat. Every new thing that one develops the other one kind of has two counter end to think that you know obviously there are different players nowadays but this is something that's probably been going on. Ever since plants evolved are crawled onto the land with their roots. And to think of all of the ways. This has been going on through time. It's just this constant change evolutionary pressure to just constantly be going back and forth with these potential pathogens and the ways you can fight them. That is so cool. Yeah i mean it's still kinda going still going on to this day like they're still evolving is still trump
