• Rice pectin methylesterase inhibitor28 OsPMEI28 encodes a functional PMEI and its overexpression results in a dwarf phenotype through increased pectin methylesterification levels., 2016, J Plant Physiol.

Genbank accession number

• Overexpression of OsPMEI28 in rice resulted in an increased level of cell wall bound methylester groups and differential changes in the composition of cell wall neutral monosaccharides and lignin content in culm tissues
• Consequently, transgenic plants overexpressing OsPMEI28 exhibited dwarf phenotypes and reduced culm diameter
• Our data indicate that OsPMEI28 functions as a critical structural modulator by regulating the degree of pectin methylesterification and that an impaired status of pectin methylesterification affects physiochemical properties of the cell wall components and causes abnormal cell extensibility in rice culm tissues
