Figure 7From: Differential activation of sporamin expression in response to abiotic mechanical wounding and biotic herbivore attack in the sweet potatoInsect bioassay. (A) The mass of leaves consumed by herbivores (Spodoptera littoralis) at the indicated time points; (B-C) The mean mass (±SE) of second instar larvae of Spodoptera littoralis reared on sweet potato leaves (n = 10) and the plant growth biomass were recorded after 7 days (B) and from 2–7 days (C) of feeding (D). The results are representative of three replicates. (* represents growth impairment of larvae).Back to article page
