Genes differentially expressed during fibre development in cotton. Top row: domesticated TM-1. Bottom row: wild var. yucatanense. Green ellipses represent time points of RNA collection, from 2 to 25 days post anthesis (DPA). Arrows represent contrasts used in the statistical model. Numbers above or inside the arrows are the number of genes differentially diagnosed for the specified contrast. For example, for the two stages 2 and 7 DPA within domesticated G. hirsutum, 1988 genes were up-regulated at 2 DPA, whereas1545 were more highly expressed at 7 DPA. Contrasts are also shown between wild and domesticated G. hirsutum; for example between TM-1 and yucatanense at 2 DPA, 2904 genes were more highly expressed in the domesticated form, while for the same contrast 2133 are up-regulated in the wild cotton.
