Abstract Pectin, a crucial constituent of plant cell walls, assumes a significant role in both plant development and cell wall fortification. The enzymatic catalyst responsible for pectin polymerization is glucuronate isomerase, also known as UDP-D-glucuronate-4-epimerase (GAE). This enzymatic process involves the utilization of UDP-α-D-galacturonic acid (UDP-GalA) as the monosaccharide donor to form the pectin skeleton. To investigate the cell wall resistance mediated by GAE of Antirrhinum majus, 8 AmGAEs genes were identified at the whole genome level. Bioinformatics analysis of their physical and chemical properties, subcellular localization, phylogeny, conserved motifs, gene structure, chromosome localization and cis-acting elements showed that all the members of the AmGAE family were alkaline hydrophilic proteins located in Golgi apparatus. The genes had resistance-related response elements such as defense and stress, methyljasmonate (MeJA), salicylic acid (SA) and abscisic acid (ABA) in the promoter region. Furthermore, RNA-seq and qRT-PCR were used to analyse and reverify the resistant and susceptible materials to S. sclerotiorum in snapdragon. The results showed that the expression of AmGAE1a, AmGAE3, AmGAE5 and AmGAE2 genes were significantly induced in the resistant material Am6 (R), while the expression of AmGAE7 and AmGAE4 genes was significantly induced in the susceptible material Am1 (S). Among them, the expression patterns of AmGAE1a, AmGAE3, AmGAE7 and AmGAE4 genes in qRT-PCR were consistent with differentially expressed genes (DEGs) by RNA-seq, and thus finally identified as candidate genes. The results provide a theoretical basis and new genetic resources of AmGAE family genes involved in the resistance to S. sclerotiorum for further study.
