Gene Details:

• MSU gene ID: LOC_Os07g38130
• RAPdb gene ID: Os07g0568700
• Gene Symbol: OsFOR1 PGIP
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In situ hybridization experiments showed the transcripts of OsFOR1 are present in young spikelet primordia and in almost all of the young floral organs.
• OsFOR1 transcript was not detected in the frizzy panicle mutant, which is defective in its spikelet formation but normal in inflorescence-meristem initiation and maintenance.
• Antisense expression of OsFOR1 resulted in an increase in the numbers of floral organs, including the stamen, carpel, palea/lemma, stigma, and lodicule.
• We have isolated a cDNA clone, OsFOR1, from the immature panicles of rice.
• OsFOR1 is highly expressed in the calli and immature and mature panicles, while detectable at only low levels in seedling roots and mature stems.
• The OsFOR1 gene encodes a polygalacturonase-inhibiting protein (PGIP) that regulates floral organ number in rice.
• The OsFOR1 (Oryza sativa floral organ regulator 1) gene encodes a protein that contains a leucine-rich repeat (LRR) domain.
• Therefore, we suggest that OsFOR1 plays a role in the formation and/or maintenance of floral organ primordia.
