#plantpathogens — Public Fediverse posts

Do you use DNA approaches to monitor plant pests or pathogens in the UK?

Fill in Beth Moore’s survey on using DNA technologies for pest and pathogen monitoring & option to sign up to be a part of focus group https://hutton.qualtrics.com/jfe/form/SV_41Omm1Snngk5XCK?Q_CHL=qr

The survey is being run as part of the plant health centre project PHG2028_01 at #JamesHuttonInstitute

I love how delightfully diabolical evolution can be.

A new article in Annual Review of Entomology is about the plant pathogens that are vectored between plants by herbivorous insects. These plant pathogens invade plant tissues and make plants sick. To get between plants they hitch a ride inside plant-feeding insects. The healthier the insect the more plants it will feed on.

So, what do the microbes do? They manufacture chemicals that make their insect hosts stronger. Several ways that they do this have been discovered "from balancing a nutritionally deficient diet" to "upgrading its defensive biochemistry against natural enemies."

Wild!

Hey folks! A friend of mine is seeing a black discoloration on thimbleberry leaves in their yard. It doesn't match any of the few things I know. Can anyone help? #plantpathogens #pnwnativeplants #nativeplants

Not a mushroom but still a fungus: Ash Rust (Puccinia sparganioidis). This family of obligate plant pathogens is highly host-specific and often can infect only one or two different species of hosts.

Understanding how the “heart” of the plant works may lead to protecting plants from pathogens

Researchers have discovered the secrets behind how plants move sugar using a protein called the SUC transporter. This breakthrough solves a long-standing mystery of the plant ‘heart’ and sheds new light on how plants defend themselves from pests.
