AGL1 — Phaseolus vulgaris

Summary

PvAGL1 (AGL1) on chromosome 8 of French bean encodes a protein with MADS-box and K-box domains, possessing RNA polymerase II transcription regulatory region sequence-specific DNA binding and DNA-binding transcription factor activity. It is associated with the specification and maintenance of floral organ identity, including stamen and ovule identity, as well as seed coat development, mucilage extrusion from the seed coat, and responses to high light intensity, UV-A, and wounding. The gene is linked to fruit shattering, seed color, seed longevity, plant male sterility, floral organ size, carpel and sepal morphology, leaf margin morphology, gibberellin biosynthesis, jasmonic acid content, nitrate uptake, high temperature stress response, and flowering time. It localizes to the nucleus, chloroplast thylakoid membrane, plant-type vacuole, Golgi, mitochondria, and cytosol. Related genes in other species are linked to silique dehiscence, seed dispersal, and reproductive organ development.
