AGL1 — Brassica napus

Summary

BnAGL1 (AGL1, SHP1) on chromosome A04 of oilseed rape encodes a MADS-box transcription factor with RNA polymerase II-specific DNA-binding and protein dimerization activities, and is also annotated with chlorophyll binding and localisation to the nucleus and chloroplast thylakoid membrane. The gene is associated with specification of floral organ identity, specification of stamen identity, dehiscence, seed coat development, mucilage extrusion from seed coat, pectin breakdown, auxin anabolism, flavonoid anabolism, lipid metabolism, embryogenesis, cellular response to high light intensity, and cellular response to UV-A. Traits linked to BnAGL1 include flower morphology trait, floral organ size, seed color, seed longevity, silique dehiscence, fruit dehiscence, seed shattering, plant male sterility, gibberellin biosynthesis trait, jasmonic acid content, flowering time trait, and high temperature stress response. Studies of related genes in other species link the family to stamen and carpel development, floral morphogenesis, seed dispersal, and meristem activity.
