Extended Data Fig. 10: eGWAS analysis of flavonoid biosynthesis genes reveals co-location with GhTT2.

a, Grey lines represent trans-eQTL regulation, while red lines indicate local eQTL regulation. Genes marked with an asterisk denote that the regulatory relationships between GhTT2 and either ANS or ANR have been experimentally validated in previous study. b, Comparison of the expression level of the two haplotypes of cis-eQTL from GhTT2. “n” indicates sample size. Center line, median; box limits, first and third quartiles; whiskers, range from minimum to maximum. The P-value was calculated by a two-tailed Student’s t-test.
