Abscisic Acid (ABA) and Salicylic Acid (SA) Content in Relation to Transcriptional Patterns in Grapevine (Vitis vinifera L.) under Salt Stress

Correlation between two phytohormone Abscisic acid (ABA) and salicylic acid (SA) accumulation and transcript pattern of VvNHX1, VvABF1, VvAREB2, VvCBF4 and VvOSM1 genes involved in grapevine (Vitis vinifera L.) adaptation against 2 dS/m seawater treatment for 1,3 and 5 days exposure has been assessed in Baladi and Halawani cultivars and B41 rootstock grapevine. Data revealed that VvNHX1, VvABF1, VvAREB2 and VvCBF4 transcript patterns were closely related with activation of ABA level in Halawani cv. Whereas, VvABF1 and VvAREB2 transcript patterns were closely related with activation of ABA level in Baladi cv. While, VvNHX1, VvABF1 and VvCBF4 transcript patterns were closely related with activation of ABA level in B41 rootstock. Indeed, VvOSM1 transcript pattern was closely related with ABA level in B41 rootstock. As for SA, VvNHX1 and VvCBF4 transcript patterns were closely related with SA level in Baladi cv. Whereas, VvAREB2 and VvABF1 transcript pattern was closely related with activation of SA level in B41 rootstock. While, VvOSM1 transcript pattern was closely related with activation of SA level in Halawani cv. However, its transcript pattern was inversely related with SA level in Baladi cv. Thereby, the current investigation suggests that transcript pattern of some genes were closely related with activation of ABA or SA or the both together; indicating that these genes could implicated in phytohormones pathway mediates salt tolerance in grapevines.
