Congratulations, Team Yang! Root microbiota regulates tiller number in rice: Cell cell.com/cell/fulltext/S0092…

Root microbiota regulates tiller number in rice

The root-associated bacterium Exiguobacterium R2567 regulates tiller number by producing cyclo(Leu-Pro), which activates the rice strigolactone signaling pathway.

More than 40 percent of #postdocs leave academia. Those who landed a coveted faculty position were more likely to have had a highly cited paper, changed their research topic between their #PhD and postdoc, or moved abroad after receiving their doctorate. pnas.org/doi/10.1073/pnas.24… @PNASNews -> nature.com/articles/d41586-0… #ScienceCareer

Our new publication @PlantPhys With a new method we found that a RBA1 variant lacking 2', 3'-CAMP/cGMP synthetase activity but retaining NADase activity does not induce cell death but confers disease resistance. The plasmid is available @Addgene

onlinelibrary.wiley.com/doi/… Arabidopsis MLKL1 (At1g64300) confers salt stress. I assume that abiotic stresses in general would activate TIR NADases leading to MLKL activation. See the discussion in our latest manuscript (Shen and Hasegawa et al 2024 Cell H&M)

Genetic mapping of the early responses to salt stress in Arabidopsis thaliana

By non-invasively screening the early responses of 191 Arabidopsis accessions to salt stress, we identified which traits contribute to growth maintenance, and their genetic constituents. Our work...

We found that plant MLKLs confer TNL-triggered immunity in parallel with RPW8-type HeLo-domain-containing NLRs (RNLs). We also show that plant MLKLs are responsible for sustained [Ca2+]cyt influx during TNL-triggered, but not CNL-triggered, immunity.
