Gene Details:

• MSU gene ID: LOC_Os05g47446
• RAPdb gene ID: Os05g0547850
• Gene Symbol: OsPDCD5
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here we report that decreased expression of OsPDCD5 caused by antisense technology could induce pollen sterility in photoperiod-sensitive rice.
• Constitutive expression of OsPDCD5 from the cauliflower mosaic virus (CaMV) 35S promoter induced programmed cell death (PCD) in transgenic rice.
• Down-regulation of the OsPDCD5 gene induced photoperiod-sensitive male sterility in rice.
• In F1 hybrids made from transgenic plants with antisense-OsPDCD5 and japonica rice varieties, lower transcript inhibition could restore fertility, under certain photoperiod and temperatures.
• OsPDCD5, is an ortholog to mammalian programmed cell death 5 gene.
• ) programmed cell death 5 (OsPDCD5) gene in rice plant.
• Overexpression of the OsPDCD5 gene induces programmed cell death in rice.
• Transcriptome analysis showed that OsPDCD5 knockout affected auxin biosynthesis, as well as the gibberellin and cytokinin biosynthesis and signaling pathways.
• Targeted mutagenesis of OsPDCD5 enhanced grain yield and improved plant architecture by increasing plant height and optimizing panicle type and grain shape.
• OsPDCD5 negatively regulates plant architecture and grain yield in rice.
• OsPDCD5 interacted directly with OsAGAP, and OsAGAP positively regulated plant architecture and grain yield in rice.
• Collectively, these findings demonstrate that OsPDCD5 is a promising candidate gene for breeding super rice cultivars with increased yield potential and superior quality.
