From: Constitutive and induced insect resistance in RNAi-mediated ultra-low gossypol cottonseed cotton
Concentration of gossypol in cotyledons as affected by plant type. Gossypol levels (μg/mg ± SE) in cotyledons from conventional cotton (Coker 312) and two ULGCS cotton lines (RNAi 1: 66-49B and RNAi 2: 66–274). One cotyledon was collected at the start of the feeding assay (day 1). The second cotyledon was collected on day four of the assay. Different capital letters over bars from the same sample day indicate a significant difference between plant types (Tukey HSD test), n = 32–36
