Fig. 6From: Identification of candidate genes for drought tolerance in coffee by high-throughput sequencing in the shoot apex of different Coffea arabica cultivarsComparative analysis of leaf histological cross sections of IAPAR59 (a and b) and Rubi (c and d) cultivars of C. arabica under control (irrigation: a and c) and drought (b and d) conditions. Samples were double stained with Schiff and NBB and observed under wide field (at the bottom left of each image) and fluorescent microscopy (A4 filter). LE = Lower (abaxial) epidermis. The white arrows indicate the fluorescent cuticle. Values of leaf cuticle thickness are given in Table 4. Bars = 20 μmBack to article page
