Abstract Background Abscisic acid (ABA) plays a crucial role in abiotic stress responses. The pyrabactin resistance (PYR)/PYR-like (PYL)/regulatory component of ABA receptor (RCAR) proteins that have been characterized as ABA receptors function as the core components in ABA signaling pathway. However. the functions of grape PYL genes in response to different abiotic stresses. https://stilleners.shop/product-category/alignment-cam-plate-kit/
