AGL1 — Phaseolus vulgaris

Summary

PvAGL1 (AGL1) on chromosome 6 of French bean encodes a protein with a K-box domain, possessing RNA polymerase II transcription regulatory region sequence-specific DNA binding and DNA-binding transcription factor activity. The gene is associated with the specification and maintenance of floral organ identity, stamen identity, and floral organ number, as well as seed coat development, mucilage extrusion, and plant ovule development. It is linked to responses to high light intensity, UV-A, and wounding, and to traits including fruit shattering, carpel shape, seed color, flower morphology, plant male sterility, seed longevity, nitrate uptake, and high temperature stress response. The product localizes to the nucleus, chloroplast thylakoid membrane, plant-type vacuole, Golgi, mitochondria, and cytosol. Studies of related genes in other species connect the family to floral morphogenesis, carpel and stamen identity, seed dispersal, and reproductive organ development.
