- Key message
- 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

- qSH1~RIL1, SH5~RI, The BEL1-type homeobox gene SH5 induces seed shattering by enhancing abscission-zone development and inhibiting lignin biosynthesis, Os05 g38120 (SH5) on chromosome 5 is highly homologous to qSH1
- SH5~RI, SHAT1, The BEL1-type homeobox gene SH5 induces seed shattering by enhancing abscission-zone development and inhibiting lignin biosynthesis, We also determined that two shattering-related genes, SHAT1 and Sh4, which are necessary for proper formation of an AZ, were induced by SH5.

- D6~OSH15~Oskn3~RLB, SH5~RI, KNOX Protein OSH15 Induces Grain Shattering by Repressing Lignin Biosynthesis Genes., Co-immunoprecipitation experiments revealed that OSH15 interacts with SH5 and qSH1, two proteins in the BELL homeobox family
- D6~OSH15~Oskn3~RLB, SH5~RI, KNOX Protein OSH15 Induces Grain Shattering by Repressing Lignin Biosynthesis Genes., Analyses of osh15 SH5-D double mutants showed that SH5 could not increase the degree of seed shattering when OSH15 was absent, indicating that SH5 functions together with OSH15
- D6~OSH15~Oskn3~RLB, SH5~RI, KNOX Protein OSH15 Induces Grain Shattering by Repressing Lignin Biosynthesis Genes., Chromatin immunoprecipitation assays demonstrated that both OSH15 and SH5 directly interact with CAD2 chromatin
- D6~OSH15~Oskn3~RLB, SH5~RI, KNOX Protein OSH15 Induces Grain Shattering by Repressing Lignin Biosynthesis Genes., We conclude that OSH15 and SH5 form a dimer that enhances seed shattering by directly inhibiting lignin biosynthesis genes
- OsAAP5, SH5~RI, The amino acid permease OsAAP5 regulates tiller number and grain yield in rice., Downregulation of OsAAP5 expression in japonica using RNA interference (Ri) and CRISPR led to increases in tiller number and grain yield, while OsAAP5 overexpression (OE) had the opposite effect
- OsIRO2~OsbHLH056, SH5~RI, Enhancement of Iron Acquisition in Rice by the Mugineic Acid Synthase Gene With Ferric Iron Reductase Gene and OsIRO2 Confers Tolerance in Submerged and Nonsubmerged Calcareous Soils., Our results show that an enhanced tolerance was observed in OsIRO2 introduced line at the early growth stage, refre1/372 introduced line in the late stage, and RI line in all stages among five types of cultivation method
