Gene Details:

• Gene ID: Zm00001eb228910
• Gene Symbol: Na2 ZmDWF1
• Gene Name: nana plant2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• We identified the molecular basis of the nana plant2 (Na2) phenotype as a loss-of-function mutation in one of the two maize paralogs of the Arabidopsis (Arabidopsis thaliana) BR biosynthetic gene DWARF1 (DWF1).The Na2 mutants exhibited severe dwarfism, suppression of tillers, altered leaf morphology, and a failure to suppress pistils in the tassel florets.
• The Na2 mutants exhibited severe dwarfism, suppression of tillers, altered leaf morphology, and a failure to suppress pistils in the tassel florets.
• Na2 Mutants Are Disrupted in the Ɗ 24-Sterol Reductase of Maize.
• Na2 mRNA Is Accumulated in Rapidly Growing Tissues of B73.
• The molecular cloning of Na2, the maize ortholog of the DWF1 gene from Arabidopsis required for the conversion of 24-methylenecholesterol to campesterol in the BR biosynthesis pathway.
• ZmDWF1 regulates leaf angle in maize.
• Overexpression of ZmDWF1 resulted in enlarged LA, indicating that ZmDWF1 is a positive regulator of LA in maize, and the regulatory framework of ZmDWF1 was created based on the results from RNA-Sequencing and yeast-two hybrid (Y2H) screening analysis.
