β-carotene concentrations in cassava storage roots were enhanced by co-expression of transgenes for deoxyxylulose-5-phosphate synthase (DXS) and bacterial phytoene synthase (crtB), mediated by the patatin type-1 promoter. Transcriptom data was generated from cassava storage roots harvetsed at 12 months after planting from confined field trial conducted in Puerto Rico. Two transgenic cassava lines DXS//PS-20 and DXS//PS-37 and a non-tranegnic control cultivar 60444 were used for the study each replicated three-times.
