Excited to share this bioRxiv where we identify another host target for a Magnaporthe effector. Here we characterise the interaction between the zinc finger fold effector (Tie1) to a conserved family of transcription factors called the Tubby-like F-box proteins (TLPs) www.biorxiv.org/content/10.6...

biorxiv.orgA Blast Fungus Effector Targets a Tubby-like F-box Protein to Suppress Plant ImmunityThe blast fungus Magnaporthe oryzae is one of the most destructive pathogens of rice, secreting effector proteins that reprogram host cells to enable infection.

Plants balance iron and immunity at the cell surface. Our new paper reveals how ubiquitin reorganizes the receptor SRF3 to coordinate both, and how this co-ordination works. Huge shoutout to Matt Platre who spearheaded and drove this tour de force! www.science.org/doi/10.1126/...

science.orgSRF3 couples cellular iron homeostasis and defense responses through ubiquitin-dependent nano-organizationIron homeostasis is a central component of host defense responses. In mammals, iron availability is rapidly adjusted through receptor mediated pathways, whereas it remains unclear how plants regulate iron homeostasis during the earliest stages of immune ...

Our data also presents molecular insight into the role of effector diversification on both, fungal virulence and avirulence function and elucidates how this relates to NLR effectivity & sustainability in disease resistance.
