Our work on chromatin evolution in brown algae is now published in @natecoevo.nature.com! We show that developmentally complex brown algae evolved without epigenetic silencing pathways long thought universal, underscoring why non-model lineages are important to study. www.nature.com/articles/s41...

New Article: "Vacuolar sorting receptors coordinate lytic vacuolar and autophagic transport for plant effector-triggered immunity" rdcu.be/eBbOG VSRs orchestrate the vacuolar sorting of immune-related proteins and autophagic degradation of bacterial effectors in ETI.

📣 NEW PREPRINT 📝 We identified evolutionary origins of many fungal effectors! We show that fungi secrete lots of antimicrobial proteins, and that some of them were repurposed by plant pathogens for host immune suppression. www.biorxiv.org/content/10.1... cc @teamthomma.bsky.social

Plant-associated fungi co-opt ancient antimicrobials for host manipulation

Evolutionary histories of effector proteins secreted by fungal pathogens to mediate plant colonization remain largely elusive. While most functionally characterized effectors modulate plant immunity, ...

Love uncovering effector virulence strategies! 😀 Our work on PopP2 targeting core components of the PEAT chromatin-remodeling complexes is now out @theplantjournal.bsky.social. doi.org/10.1111/tpj....

Three ARID proteins involved in chromatin remodeling PEAT complexes are targeted by the Ralstonia solanacearum effector PopP2 and contribute to bacterial wilt disease

The Ralstonia solanacearum effector PopP2 is a YopJ family acetyltransferase. PopP2 is known to dampen basal immune responses by acetylating defensive WRKY transcription factors, and probably by targ...
