Transcriptional Response of Structural and Regulatory Genes Involved in Isoprene Biosynthesis and its Relation to Essential Oil Biosynthesis in Response to Salicylic Acid and Abscisic Acid in Mentha piperita L.
Background: In peppermint, precursors for the biosynthesis of monoterpenes are provided by plastidial methyl-erythritol-phosphate (MEP) pathways. Objective: In order to increase our understanding of terpene metabolism in M. piperita, the effect of salicylic acid (SA) and abscisic acid (ABA) in the modulation of expression pattern of genes involved in essential oil biosynthesis and secretion wa...
متن کاملRegulatory Cross-Talks and Cascades in Rice Hormone Biosynthesis Pathways Contribute to Stress Signaling
Crosstalk among different hormone signaling pathways play an important role in modulating plant response to both biotic and abiotic stress. Hormone activity is controlled by its bio-availability, which is again influenced by its biosynthesis. Thus, independent hormone biosynthesis pathways must be regulated and co-ordinated to mount an integrated response. One of the possibilities is to use cis...
متن کاملEffects of cycloheximide on abscisic Acid biosynthesis and stomatal aperture in bean leaves.
Cycloheximide was shown to block abscisic acid (ABA) biosynthesis in nonstressed as well as in stressed Phaseolus vulgaris leaves. Leaf wilting caused by cycloheximide resulted from increased stomatal opening as judged by a decreased stomatal diffusion resistance. The inhibition of ABA biosynthesis by cycloheximide was at least partially responsible for the increase in stomatal opening as sugge...
متن کاملThe reciprocal regulation of abscisic acid and ethylene biosyntheses.
Ethylene and abscisic acid (ABA) have compact effects on plant development and stress responses. It is not well understood about the mechanism of ABA modulation in ethylene biosynthesis. In our recent research, HY5-AtERF11 regulon was evidenced to connect the ABA action and ethylene biosynthesis. In this paper, by analyzing the expression of ABA biosynthesis genes and the ABA concentration in e...
متن کاملThe plant cuticle is required for osmotic stress regulation of abscisic acid biosynthesis and osmotic stress tolerance in Arabidopsis.
Osmotic stress activates the biosynthesis of abscisic acid (ABA). One major step in ABA biosynthesis is the carotenoid cleavage catalyzed by a 9-cis epoxycarotenoid dioxygenase (NCED). To understand the mechanism for osmotic stress activation of ABA biosynthesis, we screened for Arabidopsis thaliana mutants that failed to induce the NCED3 gene expression in response to osmotic stress treatments...
متن کاملResearch Article: Extraction of abscisic acid and gibberellin from Sargassum muticum (Phaeophyceae) and Gracilaria corticata (Rhodophyta) harvested from Persian Gulf
Phytohormones are present in seaweeds but little is known about occurrence and content of them in seaweeds of Persian Gulf. The aim of this study was extraction of abscisic acid and gibberellin in Sargassum muticum and Gracilaria corticata. The seaweeds were collected bimonthly over one year at Bushehr coasts, Persian Gulf, during a range of environmental conditions. We explored new HPLC method...
