Fantastic talk by Hervé Vaucheret as part of #IHSMLaMayoraSeminars series.
Hervé presented new unpublished results on how gene silencing is triggered in plants, and left us with a clear take-home message: be careful with what you conclude based on CRISPR and transgenic lines!

By uncovering how RipAV hijacks the regulatory mechanism PUB-CPK28, and reduces BIK1 accumulation, our work reveals a sophisticated strategy of immune suppression. I would like to thank

This mechanism is not just incidental: we show that RipAV is required to keep BIK1 levels low during infection. Dampening BIK1 is a common virulence strategy in R. solanacearum — RipAC also reduces BIK1 levels via PUB4.

This modification promotes the proteasome-mediated degradation of BIK1, a core immune component required for pattern-triggered immunity. In other words, RipAV accelerates the removal of one of the plant’s most important defense proteins.

Ralstonia solanacearum causes bacterial wilt, a devastating disease in many crops. We found that its effector RipAV directly interacts with plant ubiquitin ligases (PUBs) and the kinase CPK28, both central regulators of immune signaling.

Slowly cleaning out my office to prepare for retirement. Of all of the documents and various printed stuff I have accumulated over the years that I am sending to recycling, why is it so difficult to get rid of the lab books and computer printouts from my PhD thesis 40 yrs ago?
