| description | Abscisic acid (ABA), a critical phytohormone that regulates plant development and stress response, is sensed by the ABA receptors PYR/PYL/RCAR (PYLs). The PYL genes have been widely studied in multiple plant species, while a systematic analysis of PYL genes in the genus <i>Ipomoea</i> remains unperformed. Here, a total of 13, 14, and 14 PYLs were identified in <i>Ipomoea batatas</i>, <i>Ipomoea trifida</i>, and <i>Ipomoea triloba</i>, respectively. Fragment duplication was speculated to play prominent roles in <i>Ipomoea</i> PYL gene expansions. These <i>Ipomoea</i> PYLs were classified into three subfamilies via phylogenetic analysis, which was supported by exon–intron structures and conserved motif analyses. Additionally, the interspecies collinearity analysis further depicted a potential evolutionary relationship between them. Moreover, qRT-PCR analysis showed that multiple <i>IbPYLs</i> are highly and differentially responsive to abiotic stress treatments, suggesting their potential roles in sweetpotato stress responses. Taken together, these data provide valuable insights into the PYLs in the genus <i>Ipomoea</i>, which may be useful for their further functional analysis of their defense against environmental changes. |
