Contents 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 lines
