Fig. 1From: Divergence and evolution of cotton bHLH proteins from diploid to allotetraploidExpression patterns of GhbHLH genes from transcriptome sequencing. Expression clusters were produced by Mev4.6.2. 358 bHLH genes were tested in roots (R), stems (S), leaves (L), − 3-3 DPA ovules and 5–25 DPA fibers. DPA: day post-anthesisBack to article page
