Fig. 2From: Natural variation in expression of genes associated with carotenoid biosynthesis and accumulation in cassava (Manihot esculenta Crantz) storage rootTotal carotenoid content distribution across tissue sampling. Tissue layer samples were obtained from a cross section of ten month old storage roots in five landraces with the most contrasting HPLC_DAD profile and variable amounts of total carotenoid. Total carotenoid was estimated using a spectrophotometer for landraces IAC12.829 (White SR), Cas51 (Pink SR), Cas37 (Pale Yellow SR), Cas62 (Intense Yellow SR), and Cas60 (Yellow SR). Values in parenthesis refer to p_value (p < 0.05) obtained with three biological replications by Kruskal-Wallis statistical test and significance between values is designated by different lettersBack to article page
