| 英文摘要 | Polygalacturonase is one of the pectin hydrolytic enzymes involved in various developmental and physiological processes such as seed germination, organ abscission, pod and anther dehiscence, and xylem cell formation. to date, no systematic analysis of polygalacturonase incorporating genome organization, gene structure, and expression profiling has been conducted in soybean (glycine max var. williams 82). in this study, we identified 112 gmpg genes from the soybean wm82.a2v1 genome. these genes were classified into three groups, group i (105 genes), group ii (5 genes), and group iii (2 genes). fifty-four pairs of duplicate paralogous genes were preferentially identified from duplicated regions of the soybean genome, which implied that long segmental duplications significantly contributed to the expansion of the gmpg gene family. moreover, gmpg transcripts were analyzed in various tissues using rna-seq data. the results showed the differential expression of 64 gmpgs in the tissue and partially redundant expression of some duplicate genes, while others showed functional diversity. these findings suggested that the gmpgs were retained by substantial subfunctionalization during the soybean evolutionary processes. finally, evolutionary analysis based on single nucleotide polymorphisms (snps) in wild and cultivated soybeans revealed that 107 gmpgs had selected site(s), which indicated that these genes may have undergone strong selection during soybean domestication. among them, one non-synonymous snp of gmpg031 affected floral development during selection, which was consistent with the results of rna-seq and evolutionary analyses. thus, our results contribute to the functional characterization of gmpg genes in soybean. |
