Genome-wide analysis of the PYL gene family and identification of PYL genes that respond to cold stress in Triticum monococcum L. Subsp. Aegilopoides.

ABSTRACT: Abscisic acid (ABA) is a key plant hormone that regulates plant growth and response to stress . Pyrabactin resistance 1-like (PYR/PYL) proteins are ABA receptors involved in the initial steps of ABA signaling. Triticum monococcum L. subsp. aegilopoides is an important germplasm resource for wheat. In this study, we identified 15 PYL genes from T. monococcum L. subsp. aegilopoides and found that they were distributed across five chromosomes. Based on phylogenetic analysis, we classified these genes into three subfamilies. Members of each subfamily have similar gene structures and contain a common motif. Further analysis revealed that the promoters have multiple hormone-related elements. We found 7, 33, and 49 collinear gene pairs in three different ploidy wheat species (T. urartu, T. turgid
