Gene Details:

• Gene ID: TraesCS5D02G004100
• Gene Symbol: Pina
• Gene Name: Pina
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• The deletion of the Pina and Pinb genes resulted in the loss of the softness-conferring PIN proteins in durum wheat.
• In hexaploid wheat, the tight linkage among these three genes has not been broken, such that the Ha locus haplotype (Pina-D1, Pinb-D1 and Gsp-D1) is associated with kernel texture phenotype.
• Both Pin genes have been deleted from chromosomes 5A and 5B during the evolution of durum wheat (the contributor of A and B genomes of common wheat). In contrast, all three Gsp-1 genes (from the A, B and D genomes) are conserved in common wheat.
