Gene Details:

• MSU gene ID: LOC_Os08g40030
• RAPdb gene ID: Os08g0511200
• Gene Symbol: OsCUC3
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• A single mutation in either OsCUC1 or OsCUC3 leads to defects in the establishment of the meristem/organ boundary, resulting in reduced stamen numbers and the fusion of leaves and filaments, and the defects are greatly enhanced in the double mutant.
• The osnam OsCUC3 double mutant, however, resulted in severe leaf fusion of the first two leaves, while the osnam single mutant showed a similar phenotype from the seventh leaf.
• Loss-of-function mutants for OsCUC3 resulted in no obvious defects throughout the development of the rice.
• The results indicated that OsNAM and OsCUC3 act redundantly for boundary specification during postembryonic development.
• Overall, we have described the biological functions of OsNAM and OsCUC3 in rice development and the expression characteristics of OsNAM.
