Genome-wide identification, phylogeny and expression analysis of the PME and PMEI gene families in maize.

ABSTRACT: Pectins, the major components of cell walls in plants, are synthesized and secreted to cell walls as highly methyl-esterified polymers and then demethyl-esterified by pectin methylesterases (PMEs). The PMEs are spatially regulated by pectin methylesterase inhibitors (PMEIs). In this study, 43 and 49 putative PME and PMEI genes were identified in maize, respectively. Gene structure and motif analysis revealed that members in the same paralogous pairs or in the same subgroup generally had common motif compositions and gene structure patterns, which indicates functional similarity between the closely related ZmPME/PMEI genes. Gene ontology annotation analysis showed that most of the ZmPME/PMEI genes are involved in cell wall modification and pectin catabolic process with molecular functions o
