Molecular Players Regulating the Jasmonate Signalling Network

Curr Opin Plant Biol. 2005 Oct;8(5):532-40. doi: 10.1016/j.pbi.2005.07.003.

Abstract

Many plant developmental and stress responses require the coordinated interaction of the jasmonate and other signalling pathways, such as those for ethylene, salicylic acid and abscisic acid. Recent research in Arabidopsis has uncovered several key players that regulate crosstalk between these signalling pathways and that shed light on the molecular mechanisms modulating this coordinated interaction. Genes that are involved in the regulation of protein stability through the ubiquitin-proteasome pathway (COI1, AXR1 and SGT1b), signalling proteins (MPK4) and transcription factors (AtMYC2, ERF1, NPR1 and WRKY70) form a regulatory network that allows the plant to fine-tune specific responses to different stimuli.
