AGL1 — Brassica napus

Summary

BnAGL1 (AGL1, SHP1) on chromosome C06 of oilseed rape encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding and protein dimerization activities. It is associated with the specification of floral organ identity, maintenance of floral organ 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. The gene is linked to traits including silique and fruit dehiscence, seed shattering, seed color, seed longevity, flower morphology, floral organ size, stamen and carpel morphology, plant male sterility, flowering time, and high temperature stress response. It localises to the nucleus and chloroplast thylakoid membrane. Studies of related genes in other species connect the family to seed dispersal, floral morphogenesis, and reproductive organ identity.
