FUL — Pisum sativum

Summary

PsFUL (PSAT4G046280) on chromosome 4LG4 encodes an Agamous-like MADS-box protein AGL8, a transcription factor with MADS-box and K-box domains that binds sequence-specific DNA and RNA polymerase II regulatory regions, and mediates protein dimerization. In garden pea, PsFUL is associated with the maintenance of inflorescence and floral meristem identity, inflorescence and flower development, de-etiolation, differential growth, and meristem structural organization. The gene is linked to numerous traits including flowering time, photoperiod-sensitive flowering, fruit shattering, fruit yield, seed yield, flower and floral organ morphology, petal number, leaf composition, stem elongation, and gynoecium development. PsFUL is also connected to drought tolerance, fruit dehiscence, pod shatter, valve development, meristem determinacy, and secondary growth. Studies of related genes in other species link the family to floral meristem identity, petal and sepal identity, carpel development, fruit shape, pod shatter resistance, seed yield, and plant life span.
