Conserved effectors underpin the virulence of liverwort-isolated Pseudomonas in divergent plants

Very happy to share the published version of our work on natural Marchantia-Pseudomonas interactions.

Conserved effectors underpin the virulence of liverwort-isolated Pseudomonas in divergent plants

Robinson et al. identify pathogenic Pseudomonas viridiflava in wild Marchantia polymorpha liverworts and interrogate the mechanisms enabling virulence in non-flowering and flowering plants. Their resu...

Very happy and proud to share the #Spirogyra genome: 50 Mbp small, lacking almost all plastid division proteins and many transcription factors. Kudos to all the many people involved in this multi year project!

1/13 Thankfully, both you and your plants have a lot of sophisticated ways to fight off invading pathogens.
In our new preprint, we describe a new way in which animals and plants share a common strategy to ward off harmful bacteria.

How do geminiviruses maximize their limited coding capacity? Our recent preprint uncovers splicing of viral transcripts as one more strategy used by this viral family. We show that RNA splicing is prevalent in the geminivirus TYLCV — and required for infectivity! www.biorxiv.org/content/10.1...

Amazing resources and a good lesson that bryophytes are not “simple”. BUT nothing surprising here re:immune receptor diversity, functional conservation, or transferability… 👀 academic.oup.com/plcell/artic...

The N-terminal domains of NLR immune receptors exhibit structural and functional similarities across divergent plant lineages

Plant immunity mediated by a major class of immune receptors is conserved among flowering and nonflowering plants, and these receptors have domains with si

Unfortunately we will only be running the meeting in person. The committee all agreed to keep the meeting offline since it’s a single day, small local community, and mostly ECRs presenting. We’re sorry for the inconvenience.

How do predatory wasps find their caterpillar prey?

In our new preprint on Biorxiv we show that the host plant's immune system detects herbivory to sound the alarm. 🌱🐛

Several groups have presented sc/snRNA-seq analyses of Arabidopsis leaves after bacterial infection before. Is there anything left to discover? Turns out: Yes.
