Gene Details:

• Gene ID: TraesCS4D02G040400
• Gene Symbol: Rht-D1
• Gene Name: Reduced height-1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• This reduced response to gibberellin is conferred by mutant dwarfing alleles at one of two Reduced height-1 (Rht-B1 and Rht-D1) loci.
• Here we show that Rht-B1/Rht-D1 and maize dwarf-8 (d8) are orthologues of the Arabidopsis Gibberellin Insensitive (GAI) gene. These genes encode proteins that resemble nuclear transcription factors and contain an SH2-like domain, indicating that phosphotyrosine may participate in gibberellin signalling.
• Transgenic rice plants containing a mutant GAI allele give reduced responses to gibberellin and are dwarfed, indicating that mutant GAI orthologues ( Rht-B1/Rht-D1) could be used to increase yield in a wide range of crop species.
