tailieunhanh - Defense induced by Jasmonic Acid: A Review
A number of novel JA derivatives have been synthesized, isolated, and characterized. A clearer picture of jasmonate biosynthesis and functions has emerged that in many respects resembles the synthesis and functions of prostaglandins and leukotrienes in mammalians. Jasmonates are produced from a-linolenic acid from lipids of damaged plant membranes. The biosynthesis of these signalling compounds can be triggered through the activation of cell membrane receptors by pathogens, peptide signals, or wounding. These jasmonates are widely distributed in plants and affect a various processes, including fruit ripening, production of viable pollen, root growth, and plant responses to wounding, abiotic stress, infections, and insects. |
