Fig. 2From: Combining genome-wide and transcriptome-wide analyses reveal the evolutionary conservation and functional diversity of aquaporins in cottonProtein sequence alignment of GrAQPs. Conserved transmembrane domains (TM1–6) and NPA motifs, ar/R selectivity filters, and Froger’s residues were identified in five AQP subfamilies (PIP, NIP, TIP, SIP and XIP) in G. raimondiiBack to article page
