Sheng-Yang He (Michigan State U. and HHMI) 1: Introduction to Plant-Pathogen Interactions

www.ibiology.org/plant-biolog...
Dr. Sheng-Yang He explores plant-pathogen interactions and provides an overview of a plant's basic immunological responses.
Talk Overview:
What mechanisms do plants have to fight pathogens? In this seminar, Dr. Sheng-Yang He explores plant-pathogen interactions and provides an overview of a plant's basic immunological responses. As He explains, plants have "resistant" genes, which trigger the immune response after pathogenic infections (effector-triggered immunity). Also, plants immune system can be activated by the recognition of general patterns in pathogens (pattern-triggered immunity). Understanding these interactions could aid in the prevention of disease in plants, which would be beneficial to the agricultural industry and global food security.
In his second lecture, He provides evidence on the effect of environmental factors (e.g. humidity) in the development of disease in plants. In order to understand disease susceptibility, He's laboratory studies the interaction that Arabidopsis has with the bacteria Pseudomonas syringae. He's laboratory showed that an increase in temperature and humidity increase bacterial disease severity. By genetically creating a plant that is altered in its immune system and water homeostasis, they were able to define the minimal factors that bacteria need to infect the plant.
Speaker Biography:
Dr. Sheng-Yang He is a University Distinguished Professor at Michigan State University and a Howard Hughes Medical Institute investigator. He obtained his bachelor's degree (1982) and a master's degree in plant protection (1991) from Zhejiang Agricultural University in China. He pursued his graduate degree in plant pathology (1991) at Cornell University and continued his post-doctoral training at this institution. He joined the faculty of the University of Kentucky (1993), and in 1995 he moved to Michigan State University. His lab investigates plant-pathogen interactions. They study the molecular mechanisms of infection, and how climate and microbiota affect disease in plants. For his scientific contributions, He was elected to the US National Academy of Sciences in 2015. Learn more about He's research at his lab website:

Thanks for a good talk. It made me clearly understand what is plant immune response in a short time.

[@kinzakhan9456]

Great work sir, it was quite clear easy to understand, and very informative. keep going with great efforts.

[@SuperGubster]

Succinctly and well explained! It almost goes without saying that work on plant pathology is vital, so thank you for your time!

[@aslhanv6531]

Thank you so much sir, this lecture will help me a lot and i will be wating for your next lectures if its possible

[@harshvardhangaikwad9572]

The video was fascinating. It's great to know that Plant also have immune response like animals. I knew about H H Flor hypothesis but Effector triggered immunity and Pathogen triggered immunity is a really cool stuff. Hope that in future due to disease resistant plants, there be no need of fungicides and chemical control to manage plant diseases.

Nice video, covered all the aspects of PTI and ETI

Thanks a lot. Very good presentation.

[@sasi849]

Beautifully explained

[@sarahbenzai5358]

Thank you very much 老师!!!!!
this was amazing !!!

[@spikarooni6391]

This is amazing

[@rangchu2220]

awesome

[@kailashpati7439]

Very informative lecture sir

[@greenbeecolony1911]

Very nice thank you

[@Ruizhong]

Great !!!

[@ALASKAOO7]

grazie molto interessante

Great talk, though the part of three different immune systems took me quite a while to understand. Seems like those responses are for micro pathogens. Will plants also response to other competitor plants, like weeds?

A small Caterpillar eats only a small potion of leaves. While the big Caterpillar eats the entired leaves off the tree. We goes to the Supermarket/grocery store to buy meat and others food stuff we used to survive. The different parts of the immune system is quiet to understand, just how plants respond to other plants and their weeds. The tortoise cannot swim in water but they can flow in water and a tortoise survive two to three years with out food. 3/26/20

I found the second mechanism bit hard to be understood. rest 👍
