RA Chu H., Zhang D.;
RT "The shoot apical meristem size regulated by FON4 in rice.";
RL Plant Signal. Behav. 2:115-116(2007).
CC -!- FUNCTION: Probable extracellular signal that regulates meristem
CC maintenance. May function as a putative ligand for a receptor complex
CC including FON1. Regulates the size of the floral meristem and the
CC number of floral organs. {ECO:0000269|PubMed:17012407,
CC ECO:0000269|PubMed:17056620, ECO:0000269|PubMed:19704753}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in shoot apical and axillary meristems,
CC but not in other vegetative tissues. Detected in a group of small cells
CC at the apical region of the central zone of the meristems.
CC {ECO:0000269|PubMed:17012407, ECO:0000269|PubMed:17056620}.
CC -!- DEVELOPMENTAL STAGE: Expressed during the development of the floral
CC organ primordia. No longer detected after the carpel has formed.
CC {ECO:0000269|PubMed:17012407}.
CC -!- DISRUPTION PHENOTYPE: Enlargement of the floral meristem and increased
CC number of floral organs. {ECO:0000269|PubMed:17056620}.
CC -!- SIMILARITY: Belongs to the CLV3/ESR signal peptide family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABA94631.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
