Additive epistasis between qA07-STR-1731 and qD13-STR-1792. Four combinations of alleles are presented with gray boxes indicating the JGIv3.1 reference allele (0/0:, REF) and white boxes indicating the alternative allele (1/1:, ALT). The ALT allele of the candidate genes qA07-STR-1731 and qD13-STR-1792 have higher RNA expression at 16-DPA than the REF alleles. qA07 and qD13 have an additive epistatic effect on cotton fiber strength (STR). Violin and scatter plots show 550 MAGIC RILs phenotypes and RPKM expression at 16-DPA for the four combinations of the alleles of the two candidate STR genes.
