HIGHLY METHYL ESTERIFIED SEEDS is a pectin methyl esterase involved in embryo development.

Plant physiology - 1 Mar 2015

Levesque-Tremblay Gabriel, Müller Kerstin, Mansfield Shawn D, Haughn George W

Abstract excerpt

Homogalacturonan pectin domains are synthesized in a highly methyl-esterified form that later can be differentially demethyl esterified by pectin methyl esterase (PME) to strengthen or loosen plant cell walls that contain pectin, including seed coat mucilage, a specialized secondary cell wall of seed coat epidermal cells. As a means to identify the active PMEs in seed coat mucilage, we identified seven PMEs...
