AGL1 — Brassica napus

Summary

BnAGL1 (AGL1, SHP1) on chromosome A09 of oilseed rape (Brassica napus) encodes a MADS-box transcription factor with DNA-binding and protein dimerization activity. It is associated with the specification of floral organ identity, particularly stamen and carpel development, as well as dehiscence, seed coat development, mucilage extrusion, and responses to high light intensity and UV-A. The gene has been linked to silique and fruit dehiscence, seed shattering, seed color, flower morphology, and male sterility. It is also associated with auxin and flavonoid anabolism, pectin breakdown, lipid metabolism, and embryogenesis. The product localizes to the nucleus and the chloroplast thylakoid membrane. Studies of related genes in other species link the family to seed dispersal, floral morphogenesis, and stamen and carpel identity.
