Cell wall catabolism during fruit ripening is under complex control and is key for fruit quality and shelf life. To examine the role of abscisic acid (ABA) in tomato (Solanum lycopersicum) fruit ripening, we suppressed SlNCED1, which encodes 9-cis-epoxycarotenoid dioxygenase (NCED), a key enzyme in the biosynthesis of ABA. To suppress SlNCED1 specifically(More)
The aim of this study was to obtain new insights into the mechanisms that regulate endogenous abscisic acid (ABA) levels by β-glucosidase genes during the development of watermelons (Citrullus lanatus) and under drought stress conditions. In total, five cDNAs from watermelons were cloned by using reverse transcription-PCR (RT-PCR). They included three cDNAs(More)
The ‘Elizabeth’ melon (Cucumis melo L. cv. Elizabeth) is regarded as a climacteric fruit, but it has characteristics of both climacteric and nonclimacteric fruits during the ripening stage. To clarify whether the ethylene-independent pathways during ripening were related to abscisic acid (ABA), four cDNAs that encode for key enzymes of ABA metabolism(More)
Cucumber (Cucumis sativus L.), a kind of fruit usually harvested at the immature green stage, belongs to non-climacteric fruit. To investigate the contribution of abscisic acid (ABA) to cucumber fruit development and ripening, variation in ABA level was investigated and a peak in ABA level was found in pulp before fruit get fully ripe. To clarify this point(More)
The abscisic acid (ABA) signal transduction core components in plants include the ABA receptors (PYR/PYL/RCARs), the group A type 2C protein phosphatases (PP2Cs) and the subclass III SNF1-related protein kinases 2 (SnRK2s). In this study, via homology cloning, three CsPYLs, four CsPP2Cs and two CsSnRK2s partial cDNAs were obtained in cucumber (Cucumis(More)
The purpose of this study was to investigate the role of abscisic acid (ABA) in the pre- and postharvest maturation of the nonclimacteric sweet cherry. It was found that ABA content increased rapidly at the straw-colored stage and reached its highest level 4 days before commercial harvest time. The increase in ABA level was paralleled by an increase in the(More)
In order to understand more about the role of β-glucosidase gene expression in modulating ABA level, the expression pattern of three cDNAs (VvBG1, VvBG2 and VvBG3) which encode β-glucosidase in ripening grape berries was analyzed in the presence or absence of dehydration stress. The results show that expression of these three VvBG genes was markedly(More)
