To investigate the evolutionary relationships within the PYL (Pyrabactin Resistance-Like) gene family in sugar beet (Beta vulgaris), we performed a comprehensive phylogenetic analysis using full-length amino acid sequences from Beta vulgaris, Arabidopsis thaliana, and Oryza sativa (Supplementary Material: Supplementary Table S6).These PYL proteins serve as fundamental components of the abscisic acid (ABA) signaling pathway, mediating plant responses to diverse environmental stresses, particularly drought, salinity stress, and pathogen infection (Fidler et al., 2022). The gene discussed is SFRP4; the disease is infection.
