AGL1 — Brassica napus

Summary

BnAGL1 (AGL1, SHP1) on chromosome C08 of oilseed rape (Brassica napus) encodes a MADS-box transcription factor containing K-box and MEF2-like domains, with annotated molecular functions including RNA polymerase II-specific DNA-binding transcription factor activity, protein dimerization activity, and chlorophyll binding. The gene is associated with specification of floral organ and stamen identity, dehiscence, seed coat development, mucilage extrusion, pectin breakdown, auxin and flavonoid anabolism, lipid metabolism, embryogenesis, and responses to high light intensity and UV-A. It localises to the nucleus and chloroplast thylakoid membrane. Associations with agronomically important traits include silique and fruit dehiscence, seed shattering, seed color and longevity, plant male sterility, flowering time, floral organ size and morphology, carpel and gynoecium development, leaf and trichome morphology, gibberellin biosynthesis, and jasmonic acid content. Studies of related genes in other species link the family to seed dispersal, stamen and carpel identity, and floral morphogenesis.
