Fig. 1From: Diversity, distribution of Puroindoline genes and their effect on kernel hardness in a diverse panel of Chinese wheat germplasmDiagrams of PCR amplification for Pina and Pinb. The gray boxes show coding regions for Pina and Pinb, respectively. The first step PCR reaction of Pina and Pinb (Pina-OutF/R, Pinb-OutF/R) used for amplifying Pina (1933Â bp) and Pinb (1916Â bp) genomic sequence. The second step PCR reaction of Pina and Pinb (Pina-InF/R, Pinb-InF/R) used for amplifying Pina (1239Â bp) and Pinb (1421Â bp) genomic sequenceBack to article page
