Characterization of the ABA signal transduction pathway in Vitis vinifera

The effects of abscisic acid, salicylic acid and jasmonic acid on lipid accumulation in two freshwater <i>Chlorella</i> strains

“…The plant hormone ABA regulates many key processes in plants including the response to abiotic stress and regulation of the water balance (Boneh et al, 2012). ABA could trigger stress and defense responses to protect plants from oxidative damage (Wang et al, 2010).…”

ABA-deficiency and molecular mechanisms involved in the dehydration response and ripening of citrus fruit

“…In agreement, water stress slightly changed gene expression of the subclass III SnRK2s in grape leaves (Boneh et al, 2012a).…”

“…Sun et al (2011) performed a transcriptional study in which the relationship between ABA and the PP2CAs gene-regulation was highlighted in different organs, developmental stages and in response to water stress. Studies performed in grape identified six putative PP2CAs and revealed that their expressions in leaves and roots were highly regulated by abiotic ABAincreasing stresses such as high salt concentration, cold and drought (Boneh et al, 2012a;Boneh et al, 2012b), and that sugar and exogenous ABA regulated these and other ABA-signalling genes during ripening of this non-climacteric fruit (Gambetta et al, 2011). Therefore, recent works in crops of agronomic value attempt to find potential targets for biotechnological research.…”

“…The group of SnRK2 is composed of 10 plant-specific proteins, which present a characteristic D-rich C-terminal domain that is essential for transducing the ABA signal (Yoshida et al, 2006a (Sun et al, 2011;Boneh et al, 2012a).…”

“…Nevertheless, several reports have already analyzed the expression pattern of these genes in tomato fruits (Sun et al, 2011) and in grape (Boneh et al, 2012a). Results obtained in tomato fruit showed that SnRK2s were transiently induced by exogenous ABA and highly expressed at the most immature stages, concomitantly with lowest endogenous ABA levels (Sun et al, 2011).…”
