| additional information | PG activity increases during ripening. Ripening specific pectin methylesterase, active in vivo, appears to enhance PG-mediated pectin ultra-degradation, resulting in cell wall dissolution and deciduous fruit trait. Some pectin methylesterase isozymes are apparently inactive in vivo, particularly in green fruit and throughout ripening in the Hard Pick line, limiting PG-mediated pectin depolymerization which results in moderately difficult fruit separation from the calyx | Capsicum frutescens |
