PI — Brachypodium distachyon

Summary

BdPI (BRADI_2G24940V3) on Brachypodium distachyon chromosome 2 encodes a MADS-box transcription factor with DNA-binding, protein dimerization, and kinase activities. It is associated with the specification of floral organ, petal, and stamen identity, as well as the maintenance of floral meristem identity and organogenesis. The gene is linked to seed coat development, megagametogenesis, and the regulation of vegetative-to-reproductive phase transition. Traits connected to BdPI include flower and inflorescence morphology, petal number and morphology, stamen length and morphology, carpel shape, seed longevity, bacterial blight disease resistance, photoperiod-sensitive flowering time, plant male sterility, and high temperature stress response. It localizes to the nucleus, cytoplasm, plasmodesma, and plastid. Studies of related genes in other species link the family to floral organ development, petal and stamen identity, and reproductive development.
