Fig. 1From: Pitchers of Nepenthes khasiana express several digestive-enzyme encoding genes, harbor mostly fungi and probably evolved through changes in the expression of leaf polarity genesNepenthes khasiana leaf. a, the five distinct parts/zones of the N. khasiana leaf comprising the leaf base, tendril, digestive zone, waxy zone and lid (bar = 1 cm). b-k, SEM photomicrographs of the leaf base (b, c), tendril (d, e), digestive zone (f, g), waxy zone (h, i) and lid (j, k). Barring tendril, SEM images on the left represent the adaxial surfaces while the ones on the right depict the abaxial surfaces. e is a close-up of the tendril shown in (d)Back to article page
