FZP — Oryza sativa Indica Group

Summary

BGIOSGA023741 (symbol FZP, also known as OiFZP or PUCHI) on Indica rice chromosome 7 encodes a nuclear-localised AP2/ERF domain-containing protein with sequence-specific DNA binding and transcription regulatory activity. This gene is associated with floral meristem growth and determinacy, bract development, flower development, regulation of secondary shoot formation, and downregulation of lateral root development. It is linked to ethylene-mediated signalling, nodulation, defense and stress responses, and DNA-dependent transcription regulation. Phenotypic associations include panicle architecture, spikelet formation and abortion, heading date, tiller and culm development, lateral root initiation and spacing, phyllotactic patterning, floral organ identity, callus formation, and cell death. Studies of related genes in other species link the family to grain yield, spikelet number, kernel number, ear length, grain size, tiller number, and inflorescence branching traits.
