Gene Details:

• MSU gene ID: LOC_Os06g46350
• RAPdb gene ID: Os06g0677000
• Gene Symbol: DEP3
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In the current study, we characterized a novel dense and erect panicle (EP) mutant, DEP3, derived from the Oryza sativa ssp.
• The panicle of the DEP3 mutant remained erect from flowering to full maturation, whereas the panicle of the wild type plant began to droop after flowering.
• Fine mapping and candidate gene analysis of dense and erect panicle 3, DEP3, which confers high grain yield in rice (Oryza sativa L.).
• Anatomical observations revealed that the DEP3 mutant had more small vascular bundles and a thicker culm than wild type plants, explaining the EP phenotype.
• Taken together, our results indicated that the patatin-like PLA2 might play a significant role in the formation of vascular bundles, and that the DEP3 mutant may provide another EP resource for rice breeding programs.
• The DEP3 mutation also regulated other panicle characteristics, including panicle length, grain shape and grain number per panicle.
• Overexpression of OrMKK3 influenced the expression levels of the grain size-related genes SMG1, GW8, GL3, GW2, and DEP3.
