Gene Details:

• MSU gene ID: LOC_Os01g01620
• RAPdb gene ID: Os01g0105900
• Gene Symbol: DNL-4
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The DNL-4 mutant showed reduced plant height and leaf blade width compared to the wild type, and increased leaf inclination.
• These results suggest that DNL-4 expression is involved in modulating plant height and leaf growth.
• To understand DNL-4 function in rice, we analyzed the expression levels of leaf growth-related genes, such as NAL1, NAL7, and CSLD4, in the DNL-4 mutant.
• The observation that DNL-4 expression corresponded with that of NAL1 and NAL7 is consistent with the narrow leaf phenotype of the DNL-4 mutant.
• These results suggest that DNL-4 regulates plant height and leaf structure in rice.
• Furthermore, DNL-4 expression also affects productivity in rice: the DNL-4 mutant exhibited reduced panicle length and grain width compared with the wild type.
• The morphological defects of the mutant were caused by the suppressed expression of the DNL-4 gene, which encodes a pfkB carbohydrate kinase protein.
