PHAVU_003G281000 — Phaseolus vulgaris

Summary

PHAVU_003G281000, designated PvAP1, encodes a MADS-box transcription factor on French bean chromosome 3. The product contains MADS-box and K-box domains and is annotated with DNA-binding transcription factor activity, chromatin binding, and transcriptional co-regulator functions. PvAP1 is associated with floral whorl development, regulation of double fertilization, release of seed from dormancy, abscisic acid breakdown, and proanthocyanidin metabolism. It is linked to numerous traits including fruit shattering, flower and sepal morphology, seed color, leaf margin serration, fruit yield, and vegetative-to-reproductive phase transition. The gene is also associated with floral meristem identity, fruit development, pod shatter, and inflorescence determinacy. Related genes in other species are linked to petal and stamen identity, seed yield, pod shatter resistance, and temperature-responsive flowering.
