Wasternack, C. & Hause, B. Jasmonates: biosynthesis, perception, signal transduction and action in plant stress response, growth and development. An update to the 2007 review in Annals of Botany Annals of Botany 111, 1021-1058, (2013) DOI: 10.1093/aob/mct067

Background: Jasmonates are important regulators in plant responses to biotic and abiotic stresses as well as in

development. Synthesized from lipid-constituents, the initially formed jasmonic acid is converted to different

metabolites including the conjugate with isoleucine. Important new components of jasmonate signalling including

its receptor were identified, providing deeper insight into the role of jasmonate signalling pathways in stress

responses and development.

Scope: The present review is an update of the review on jasmonates published in this journal in 2007. New data

of the last five years are described with emphasis on metabolites of jasmonates, on jasmonate perception and

signalling, on cross-talk to other plant hormones and on jasmonate signalling in response to herbivores and pathogens,

in symbiotic interactions, in flower development, in root growth and in light perception.

Conclusions: The last few years have seen breakthroughs in the identification of JASMONATE ZIM DOMAIN

(JAZ) proteins and their interactors such as transcription factors and co-repressors, and the crystallization of the

jasmonate receptor as well as of the enzyme conjugating jasmonate to amino acids. Now, the complex nature of

networks of jasmonate signalling in stress responses and development including hormone cross-talk can beaddressed.
