Overexpression of the Potato <i>StPYL20</i> Gene Enhances Drought Resistance and Root Development in Transgenic Plants.

ABSTRACT: Drought is a primary limiting factor for potato growth. PYR/PYL/RCAR (referred to hereafter as PYL) proteins, as receptors for abscisic acid (ABA), play a crucial role in the plant response to drought stress. However, the underlying mechanisms of this control remain largely elusive in potatoes. In this study, a potato StPYL20 gene was identified through genome-wide investigation and transcriptome analysis under drought stress. Molecular feature analysis revealed that the StPYL20 gene exhibits the highest expression level in tubers, and is significantly up-regulated under ABA and drought stress conditions. The StPYL20 protein harbors a conserved domain exclusive to the PYL family. Further functional analysis showed that both transient and stable expressions of StPYL20 i
