UniprotDEVELOPMENTAL STAGE: Accumulates in the pollen tube nucleus during pollen tube growth through the pistil. {ECO:0000269|PubMed:23791732}.
UniprotTISSUE SPECIFICITY: Expressed in pollen grains and pollen tube (PubMed:23791732, PubMed:24278028). Mostly expressed in mature pollen grains, and, to a lower extent, in inflorescences and siliques (PubMed:24278028). {ECO:0000269|PubMed:23791732, ECO:0000269|PubMed:24278028}.
Functional Description ? help Back to Top
Source Description
TAIREncodes a putative transcription factor, member of the R2R3 factor gene family (MYB120).
UniProtTranscription activator (PubMed:24278028). Binds to 5'-CAACTGTC-3' and/or 5'-TAACAAA-3' motif in target gene promoter to promote their expression (By similarity). Together with MYB97 and MYB101, functions as a male factor that controls pollen tube-synergid interaction in fertilization. Required for pollen tube growth arrest and sperm cell release in the female gametophyte, probably via the regulation of pollen tube-specific gene expression (PubMed:24278028, PubMed:23791732). {ECO:0000250|UniProtKB:O80883, ECO:0000269|PubMed:23791732, ECO:0000269|PubMed:24278028}.

  1. All these results indicate that MYB97, MYB101 and MYB120 participate in pollen tube reception, possibly by controlling the expression of downstream genes.
