Expression profiles of GhGRF genes in 15 tissues. a Roots, stems, leaves, sepals, petals, pistils, filaments, fiber-bearing ovules on 0, 1, 3, and 5 d post-anthesis (DPA), and fibers on 10, 15, 20, and 25 DPA were sampled. b Expression analysis of six GhGRF genes marked with red fonts in a by qRT-PCR in five samples
