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 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

How do chromatin remodelers use #IDRs to find TF binding partners? In our new Molecular Cell paper, we show that β-catenin is an adaptor that links SWI/SNF (cBAF) subunit ARID1A with binding partners via IDR-domain interactions. www.cell.com/molecular-ce...

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...
