Fig. 4From: The organ-specific differential roles of rice DXS and DXR, the first two enzymes of the MEP pathway, in carotenoid metabolism in Oryza sativa leaves and seedsContents and composition of carotenoids and chlorophylls in the leaves of PGD1::OsDXS2 and PGD1::OsDXR transgenic plants relative to NT plants. a Carotenoid levels determined by HPLC analysis of T4 leaf tissues harvested from three independent transgenic plants for each construct. b Chlorophyll absorbance in the same leaves as in a measured by spectrophotometry. NT represents non-transgenic rice plants (Oryza sativa L. cv. Ilmi). All data are represented as the mean ± SE of three independent measurements. Statistical analyses were performed using a two-tailed Student’s t-test, and significant differences were indicated by a p value (** p < 0.01 and *** p < 0.001). Different varieties of transgenic plants are represented in different colors, such as green and light-green in the bar graph, and the X-axis labeling consists of three independent-transgenic plant linesBack to article page
