Gene Details:

• Gene ID: TraesCS7A02G514400
• Gene Symbol: Pinb2-1
• Gene Name: Pinb2-1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• We developed new Pinb2 allele specific markers and demonstrated their usefulness by identifying new Pinb2 alleles in Triticeae species performing an association analysis of Pinb2 with kernel hardness.
• Pinb and Pinb2 loci with kernel hardness phenotypes was determined by a Chi-square test of independence.
• Using the high-quality bread wheat reference genome, we show that PINB2 are encoded by three homoeologous loci Pinb2 not syntenic to the Hardness locus, with Pinb2-7A locus containing three tandem copies.
• PINB2 proteins have several features conserved for the Pin/Pinb2 phylogenetic cluster but lack a structural basis of significant impact on kernel hardness. Pinb2 are seed-specifically expressed with varied expression levels between the homoeologous copies and among wheat varieties.
