Structural Requirements of Jasmonates and Synthetic Analogues as Inducers of Ca2+Signals in the Nucleus and the Cytosol of Plant Cells

摘要

Octadecanoid-derived phytohormones,such as jasmonates and 12-oxophytodienoic acid(OPDA;1)as well as their synthetic analogues(Scheme 1),induce various physiological responses in tissues and cell cultures of different plant species.Although jasmonates are known to mediate abiotic and biotic stress including wounding,and pathogen and herbivore attack,there is only limited knowledge about jasmonate-induced signaling pathways that initiate subse quent cellular responses.
