Última Structural dynamics and divergence of the polygalacturonase gene family in land plants Nature Precedings Soon-Jae Kwon; Jae-Han Son; Kyong-Cheul Park; Hae-Young Oh; Pyeung-Hyeun Kim; Woo-Hyeon Byeon; Nam-Soo Kim. A distinct feature of eukaryotic genomes is the presence of gene families. The polygalacturonase (PG) (EC3.2.1.15) gene family is one of the largest gene families in plants. PG is a pectin-digesting enzyme with a glycoside hydrolase 28 domain. It is involved in numerous plant developmental processes. The evolutionary processes accounting for the functional divergence and the specialized functions of PGs in land plants are unclear. Here, phylogenetic and gene structure analysis of PG genes in algae and land plants revealed that land plant PG genes resulted from differential intron gain and loss, with the latter event predominating. PG genes in land plants contained 15 homologous intron blocks and 13 novel intron blocks. Intron position and phase were not...
