Gene Details:

• MSU gene ID: LOC_Os05g38120
• RAPdb gene ID: Os05g0455200
• Gene Symbol: SH5 RI
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The BEL1-type homeobox gene SH5 induces seed shattering by enhancing abscission-zone development and inhibiting lignin biosynthesis.
• Gene isolation revealed that RI encodes a BELL1-type homeodomain transcRIption factor, similar to Arabidopsis PENNYWISE/ BELLRINGER/REPLUMLESS, and is expressed in the specific regions within the inflorescence and branch meRIstems where their descendant meRIstems would soon initiate.
• In addition, both RI and RIL1 seem to be involved in meRIstem maintenance, because the RI RIl1 double mutant failed to establish or maintain the shoot apical meRIstem duRIng embryogenesis.
• DuRIng early inflorescence development, the timing and arrangement of pRImary branch meRIstem (pBM) initiation was disturbed in both RI and RI RIl1/+ plants.
• Genetic combination of an RI homozygote and a mutant allele of RI-LIKE1 (RIL1) (designated RI RIl1/+ plant), a close paralog of RI, enhanced the RI inflorescence phenotype, including the abnormalities in branch phyllotaxy and rachis internode patterning.
