Comparison of GaGIR1 and GaMYB25-like between BM13H and the fuzzless accessions. (A) Sequence comparison of the promoter and ORF regions of GaGIR1 in different accessions. Only nucleotides different to BM13H are shown and SNPs that result in amino acid changes are in red. Haplotype I is BM13H. Haplotype Ⅱ contains accessions #47, NANTONG, #6, NAN.GINGJING, and JAI.ZIHUA. Haplotype Ⅲ contains accessions CHANG ZI #1 and BANI. (B) Sequence comparison of the promoter and ORF regions of GaMYB25-like. Exons are indicated by the black boxes, and SNPs that result in amino acid changes are in red. (C) Expression profiles of GaGIR1 in 0-5 dpa ovules of the fuzzless accessions JAI.ZIHUA, CHANG ZI #1, and fuzzy-linted accession BM13H. (D) Expression profiles of GaMYB25-like in 0-5 dpa ovules of the fuzzless accession JAI.ZIHUA and fuzzy accession BM13H. * and ** indicate the significant differences with a probability of 0.05 and 0.01, respectively.
