Gene Details:

• Gene ID: TraesCS2A02G081900
• Gene Symbol: PPD-A1
• Gene Name: PPD-A1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• No candidate mutation was found in the 2B PRR gene but polymorphism within the 2B PRR gene cosegregated with the Ppd-B1 locus in a doubled haploid population, suggesting that insensitivity on 2B is due to a mutation outside the sequenced region or to a closely linked gene.
• Photoperiod insensitivity can also be conferred by mutation at a homoeologous locus on chromosome 2B (Ppd-B1).
• Varieties with the photoperiod insensitive Ppd-D1a allele which causes early flowering in short (SD) or LDs had a 2 kb deletion upstream of the coding region.
• Five Ppd-D1 alleles were found but only the 2 kb deletion was associated with photoperiod insensitivity.
