OsCUC3

• Symbol: OsCUC3
• MSU: LOC_Os08g40030
• RAPdb: Os08g0511200

• The osa-miR164 target OsCUC1 functions redundantly with OsCUC3 in controlling rice meristem/organ boundary specification, 2020, New Phytol.
• OsmiR164-targeted OsNAM, a boundary gene, plays important roles in rice leaf and panicle development, 2020, Plant J.

Genbank accession number

• 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
