Pectins are major components of cell walls in plants. Pectin methylesterases (PMEs) and pectin methylesterase inhibitors (PMEIs) play crucial roles synthesis metabolism. Overall, 28 putative DkPMEs 29 DkPMEIs were identified from the D. kaki genome. According to phylogenetic analysis, DkPME/DkPMEI proteins can be classified into four five clades, respectively. Motif gene structure analysis show...
