A switch–rheostat circuit governs quorum sensing homeostasis in a phytopathogen

Natural variation in soybean perception of bacterial quorum-sensing signals shapes primed defense

Soybean genotypes differ heritably in their ability to convert a bacterial quorum-sensing signal into primed phytoalexin defense, revealing this translation step as a quantitative, polygenic trait.

Transcriptional activation of plant immunity by salicylic acid.

It is shown that SA stabilizes the SA-binding domain of NPR1 and allosterically promotes its interaction with MED15A, a subunit of the Mediator complex, which provides a mechanistic resolution to the longstanding question of how SA promotes transcriptional activation during plant immune responses.

A conserved partner-switching system controls terminal differentiation in multicellular cyanobacteria

A canonical PSS is identified that governs heterocyst differentiation in the multicellular cyanobacterium Anabaena sp.

Deciphering the tomato defense network againstHelicoverpa armigera: From transcriptional reprogramming to biochemical changes.

Helicoverpa armigera (Hübner) is able to feed on more than 280 host plants; however, the mechanisms that allow it to persist on such a wide range of hosts may involve transcriptional reprogramming and biochemical alternations which are still not well understood. Therefore, we analyzed the transcriptional responses of s...

A conserved hexapeptide switch controls autoinhibition of plant cytosolic invertases

Interplay between different SHP/Rgg quorum sensing systems that control production of post-translationally modified peptides in Streptococcus thermophilus.

This study has revealed that individual SHP/Rgg systems function autonomously but that their activity is further shaped by crosstalk involving both SHP- and DNA-binding, and underscore that these systems should be thoroughly characterized at the strain level to allow precise, targeted modifications.
