  • Nguyen, H.P.; Jeong, H.Y.; Jeon, S.H.; Kim, D.; Lee, C.
    Rice pectin methylesterase inhibitor28 (OsPMEI28) encodes a functional PMEI and its overexpression results in a dwarf phenotype through increased pectin methylesterification levels (2017), J. Plant Physiol., 208, 17-25 .

additional information rice contains 49 PMEIs, including OsPMEI28 Citrus sinensis
pectin methylesterase inhibitor28 OsPMEI28, UniProt ID Q0J8J8, recombinant expression in Oryza sativa cv. Dongjin via Agrobacterium tumafaciens LBA4404-mediated transformation, RT-PCR and real-time PCR expression analysis. Pectin methylesterases (PMEs) belonging to carbohydrate esterase family 8 cleave the ester bond between a galacturonic acid and an methyl group. The resulting change in methylesterification level plays an important role during the growth and development of plants. Optimal pectin methylesterification status in each cell type is determined by the balance between PME activity and posttranslational PME inhibition by PME inhibitors (PMEIs). Cloning, sequence analysis, and tissue-specific expression of OsPMEI28, overview Citrus sinensis
