A mechanistic framework for the recognition of chemically diverse brassinosteroids by BRI1-family receptor kinases Brassinosteroids (BRs) are chemically diverse plant steroid hormones produced via a branched biosynthetic pathway. The potent BR brassinolide is sensed by the membrane receptor kinase BRI1 and a SERK ...

The sTDIF signaling peptide modulates the root stele diameter and primary metabolism to accommodate symbiotic nodulation Teyssendier de la Serve et al. identify a novel symbiotic response induced by nitrogen-fixing rhizobia on host plant roots, corresponding to a stele diameter enlargement. This response requires a TDIF...

Katherine Denby on stage at MBP2025. Her slide has the headline "How do I choose a journal to publish in?" The points are: Scope - look at journal content, read author guidelines Ownership - at least part society owned Integrity Author experience - timelines, editorial board culture Diversity of editorial board Promotion of papers Contribution to the scientific community

Very informative talk by @katherinedenby.bsky.social, EiC of @theplantjournal.bsky.social, on scientific publishing in the #PlantSciences. #MBP2025

Her points on how to choose a journal to publish in are below.

Happy to see that my favorite journals fit the bill. 👌
