Differential impact of lipoxygenase 2 and jasmonates on natural and stress-induced senescence in Arabidopsis.
Jasmonic acid and related oxylipins are controversially discussed to be involved in regulating the initiation and progression of leaf senescence. To this end, we analyzed profiles of free and esterified oxylipins during natural senescence and upon induction of senescence-like phenotypes by dark treatment and flotation on sorbitol in Arabidopsis (Arabidopsis thaliana). Jasmonic acid and free 12-...
متن کاملOptimization of jasmonates bioproduction
Introduction Several studies have shown that jasmonates (jasmonic acid, (+)-7-isojasmonic acid and methyl jasmonate) exhibit potential anticancer activity, with the advantage of displaying selective cytotoxicity to cancer cells that spares normal lymphocytes to this function [1]. This class of compounds is present in several families of plants, being also produced by certain microorganisms, inc...
متن کاملBioproduction and extraction of jasmonates
Introduction Jasmonates are a growing class of compounds of vegetable origin which present phytoregulator activity and toxicity against some types of cancer cells. Additionally the jasmonates have also shown activity against some types of nematodes [1]. Jasmonates available on the market are of plant origin or synthetic, present costs are still high. Like plants, some microorganisms have the po...
متن کاملPhysiological Changes during Postharvest Senescence of Broccoli 1565 Physiological Changes during Postharvest Senescence of Broccoli1
The objective of this work was to determine the early physiological changes throughout shelf life of fresh broccoli (Brassica oleracea L. var. italica) cv. Piracicaba Precoce at 25oC and relative humidity of 96% in the dark until complete senescence. Head inflorescences showed lack of turgidity and commercial value when weight loss reached up to 5%, coinciding with 48 hour after harvest. Chloro...
متن کاملCircadian control of jasmonates and salicylates
Plants have evolved robust mechanisms to perceive and respond to diverse environmental stimuli. The plant phytohormones jasmonates and salicylates play key roles in activating biotic stress response pathways. Recent findings demonstrate that basal levels of both jasmonates and salicylates in Arabidopsis are under the control of the circadian clock and that clock-controlled jasmonate accumulati...
