RGL1 — Arabidopsis thaliana

Summary

AT2G22620, designated RGL1 (rhamnogalacturonan lyase 1) in Arabidopsis thaliana, encodes a rhamnogalacturonan endolyase (EC 4.2.2.23) with rhamnogalacturonan endolyase activity, classified under the polysaccharide lyase 4 family and containing RG-lyase II and III domains. The enzyme localizes to the plant-type cell wall, vacuole, and extracellular space. RGL1 is associated with cell adhesion, histogenesis, megagametogenesis, anther development, seed development and germination, floral organ development, gibberellin signaling and biosynthesis, carbohydrate metabolism, proline metabolism, meiosis, syngamy, and cell division. It has been linked to traits including leaf position, gibberellic acid sensitivity, proline content, trichome morphology, floral organ development, leaf senescence, seed growth, and flowering time. Phenotypic associations include floral development, gibberellin signaling, flowering, embryo sac development, leaf expansion, stem elongation, leaf senescence, trichome branching, dehydration tolerance, and flowering time. Studies of related genes in other species connect the family to fruit firmness and root length.
