The ethylene-regulated expression of CS-ETR2 and CS-ERS genes in cucumber plants and their possible involvement with sex expression in flowers.
It has been reported that ethylene production by cucumber plants is strongly related to the sex expression of their flowers. It has also been shown that both CS-ACS2 gene expression and ethylene evolution are much greater in gynoecious cucumber plants than monoecious ones. To investigate the action mechanism of ethylene in the induction of femaleness of cucumber flowers, we isolated three ethyl...
متن کاملBrassinosteriod-induced Femaleness in Cucumber and Relationship to Ethylene Production
The Cucurbitaceae family is noted for a diversity of sex expression phenotypes. Typically, a phase of male fl owers precedes either female or bisexual fl ower production. Sex determination of individual fl owers is regulated by a combination of genetic, environmental, and hormonal factors. Ethylene, auxins, and gibberellins have all been shown to infl uence fl ower sex expression in cucurbits. ...
متن کاملCloning of a cDNA for a 1-aminocyclopropane-1-carboxylate synthase that is expressed during development of female flowers at the apices of Cucumis sativus L.
In cucumber (Cucumis sativus L.) plants, it has been reported that a high correlation existed between the evolution of ethylene from the apices and the development of female flowers. We isolated three distinct cDNA encoding 1-aminocyclopropane-1-carboxylate (ACC) synthase from cucumber. Among of these, only CS-ACS2 mRNA was detected at the apices of gynoecious cucumber in which female flowers w...
متن کاملPossible involvement of CS-ACS1 and ethylene in auxin-induced peg formation of cucumber seedlings.
BACKGROUND AND AIMS Cucumber (Cucumis sativus) seedlings develop a peg on the concave side of the gravitropically bending transition zone between the hypocotyl and the root after seed germination. Peg initiation occurs in response to auxin when its levels in the concave side of the transition zone exceed a particular threshold through the graviresponse. Ethylene also plays an important role in ...
متن کاملEffects of High Intensity Interval Training on the Gene Expression of PGC1-Α, CS and P-53 in the Cardiomyocyte of Male Obese Rats in Type 2 Diabetes
Introduction: Exercise training with different intensity regulates metabolism at the cellular level by regulating the expression of genes involved in mitochondrial biogenesis in diabetic patients. The aim of this study was to evaluate the effect of 4 weeks of high intensity interval training on the expression of PGC-1α, CS and p-53 genes in the cardiomyocytes of obese male rats with type 2 diab...
