Gene: Sopen07g033560

General Information

Description Encodes a protein with pectin methylesterase activity. No change in activity were detected in mutants defective in this gene, which was interpreted as a result of redundancy of product function with other pectin methylesterases. The gene product is required for pollen separation during normal development. In qrt mutants, the outer walls of the four meiotic products of the pollen mother cell are fused, and pollen grains are released in tetrads.May be required for cell type-specific pectin degradation. | QUARTET 1 (QRT1) | FUNCTIONS IN: pectinesterase activity | INVOLVED IN: pectin catabolic process | LOCATED IN: endomembrane system, cell wall, plant-type cell wall | EXPRESSED IN: 8 plant structures | EXPRESSED DURING: 5 post anthesis, sepals enclosing floral bud, petal differentiation and expansion stage, fruit development stages | CONTAINS InterPro DOMAIN/s: Pectin lyase fold/virulence factor , Pectinesterase, catalytic , Pectin lyase fold | BEST Arabidopsis thaliana protein match is: Pectin lyase-like superfamily protein
