Expression profile of OleurAQP genes from the cultivated Olea europaea cv. Picual in different physiological conditions. OleurAQsP are grouped by subfamily. Fr, fruit; Fl, flower; Le, leaf; Me, meristem; Ro, root; St, stem. Control assays are marked C. h, hours post treatment; d, days post treatment. The horizontal color scales at the bottom of the figure represent the normalized expression of the aquaporins in terms of reads per kilobase of transcript per million mapped reads (RPKM). Expression levels are displayed by the depth of red, and the related values are detailed in Tables S4 and S5.
