Fig. 4.

Conserved motifs of aquaporin proteins and exon-intron organization of corresponding coding genes in cucumber. a The motifs were identified by MEME tools. Twenty motifs (1–20) were indicated by different colored numbers (1–20). b Exon-Intron structure of 39 cucumber aquaporins genes. Untranslated Regions (UTRs) are represented by red and green boxes, coding regions (CDS) are shown as yellow round-corner rectangle, and introns are shown as black lines
