Expression patterns of AQP genes under salt stresses in G. davidsonii and G. hirsutum. A heat map of expression was generated using transcriptome data of roots under salt stress and control conditions at 12 h (RS12), 24 h (RS24), 48 h (RS48), 96 h (RS96) and 144 h (RS144) in G. davidsonii. Six time points of salt stress were 0 h (CK-0 h), 6 h (NaCl-6 h), 12 h (NaCl-12 h), 24 h (NaCl-24 h), 48 h (NaCl-48 h) and 72 h (NaCl-72 h) in G. hirsutum acc. TM-1. The color represented AQPs expression levels normalized by Log2 (FPKM+ 1). Colored squares indicated expression levels from 0 (blue) to 11 or 12 (red). Gray squares indicated that no gene was found in that species. The clustered tree of hierarchical clustering model was showed on the left
