A wheat allene oxide cyclase gene enhances salinity tolerance via jasmonate signaling.
One of the two branches of the α-linolenic acid metabolism pathway is catalyzed by 12-oxo-phytodienoic acid reductase I, and the other is involved in jasmonic acid (JA) synthesis. The former is known to be active in the response to salinity tolerance in wheat (Triticum aestivum), but the participation of the latter in this response has not been established as yet. Here, the salinity-responsive ...
متن کاملCloning of allene oxide cyclase gene from Leymus mollis and analysis of its expression in wheat–Leymus chromosome addition lines
Leymus mollis (Triticeae; Poaceae) is a useful genetic resource for wheat (Triticum aestivum L.) breeding via wide hybridization to introduce its chromosomes and integrate its useful traits into wheat. Leymus mollis is highly tolerant to abiotic stresses such as drought and salinity and resistant to various diseases, but the genetic mechanisms controlling its physiological tolerance remain larg...
متن کاملIncreased tolerance to salt stress in OPDA-deficient rice ALLENE OXIDE CYCLASE mutants is linked to an increased ROS-scavenging activity
Salinity stress represents a global constraint for rice, the most important staple food worldwide. Therefore the role of the central stress signal jasmonate for the salt response was analysed in rice comparing the responses to salt stress for two jasmonic acid (JA) biosynthesis rice mutants (cpm2 and hebiba) impaired in the function of ALLENE OXIDE CYCLASE (AOC) and their wild type. The aoc mut...
متن کاملMolecular cloning of allene oxide cyclase. The enzyme establishing the stereochemistry of octadecanoids and jasmonates.
Allene oxide cyclase (EC ) catalyzes the stereospecific cyclization of an unstable allene oxide to (9S,13S)-12-oxo-(10,15Z)-phytodienoic acid, the ultimate precursor of jasmonic acid. This dimeric enzyme has previously been purified, and two almost identical N-terminal peptides were found, suggesting allene oxide cyclase to be a homodimeric protein. Furthermore, the native protein was N-termina...
متن کاملCloning and characterization of peanut allene oxide cyclase gene involved in salt-stressed responses.
In this study, the full-length cDNA encoding allene oxide cyclase (AhAOC) was isolated from peanut (Arachis hypogaea L.). The deduced amino acid sequence of AhAOC showed high homology with other plant AOCs. The transcript of AhAOC was found to be abundantly expressed in roots. Expression analysis demonstrated that AhAOC was induced by abscisic acid, methyl-jasmonic acid, salicylic acid, salinit...
