Gene Details:

• Gene ID: Zm00001eb216610
• Gene Symbol: D9 ZmGRAS44 ZmGAI
• Gene Name: dwarf plant9
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Maize contains two genetic loci encoding DELLA proteins, dwarf plant8 (d8) and dwarf plant 9 (D9).
• Maize DELLA Proteins dwarf plant8 and dwarf plant9(D9) as Modulators of Plant Development.
• Overexpression of the D9-1 allele delayed flowering in transgenic maize, while overexpression of the D9 allele led to earlier flowering.
• The gibberellin-insensitive D9-1 was found to produce dwarfing and, notably, earlier flowering in Arabidopsis.
• D9-1 causes dwarfing and flowering time shifts in transgenic Arabidopsis and maize.
• D9 produces good pollen and large, nearly normal, ears.
• This is consistent with D8 and D9 mutants which are known to have reduced anther exertion causing varying degrees of male sterility in maize.
