Gene Details:

• MSU gene ID: LOC_Os02g04520
• RAPdb gene ID: Os02g0137800
• Gene Symbol: RGG2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• By measuring the length of the second leaf sheath after gibberellin (GA3 ) treatment and the GA-induced -amylase activity of seeds, we found that RGG2 is also involved in GA signaling.
• The expression levels of RGG2 are significantly higher than those of other rice G -encoding genes in all tissues tested, suggesting that RGG2 plays essential roles in rice growth and development.
• These results demonstrate that RGG2 acts as a negative regulator of plant growth and organ size in rice.
• By regulating cell expansion, RGG2 overexpression in Nipponbare (NIP) leads to reduced plant height and decreased grain size.
• In summary, we propose that RGG2 may regulate grain and organ size via the GA pathway and that manipulation of RGG2 provides a novel strategy for rice grain yield enhancement.
