Gene Details:

• MSU gene ID: LOC_Os10g39130
• RAPdb gene ID: Os10g0536100
• Gene Symbol: OsMADS56 GL10
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Overexpression of OsMADS56 (56OX) also resulted in delayed flowering under LD.
• These observations imply that OsMADS50 and OsMADS56 function antagonistically through OsLFL1-Ehd1 in regulating LD-dependent flowering.
• OsMADS50 and OsMADS56 function antagonistically in regulating long day (LD)-dependent flowering in rice.
• 8, OsMADS56 encoding a MADS-box transcription factor, was performed in this study.
• In these populations, decreased grain weight and size were associated with a reduction in the expression of OsMADS56.
• In transgenic populations of OsMADS56 driven by a strong constitutive promoter, grain weight and size of the positive plants were significantly higher than those of the negative plants.
• Cloning of OsMADS56 provides a new gene resource to improve grain weight and size through molecular design breeding.
• Control of Thousand-Grain Weight by OsMADS56 in Rice.
• GL10 regulates grain length by promoting greater longitudinal cell growth in the grain glume.
• 0-kb deletion in the first exon that abolishes its transcription, results in shorter grain length, lower grain weight and delayed flowering in GL10 plants.
• The knockout of GL10 in the HJX74 background leads to grain phenotypes similar to that of NIL-GL10, while overexpression of GL10 results in increased grain length and weight and earlier heading date.
• Our findings reveal an allelic variation of GL10 that may explain differences in grain length among modern cultivars and could be used to breed rice varieties with optimized grain shape.
• Additionally, GL10 participates in the regulation of gibberellic acid (GA) signaling pathway genes in young panicle tissues.
