Molecular Detection of Transgenes in Improved Varieties of Cowpea

Cowpea is one of the most consumed food in Africa. Recombinant DNA technology has been used to insert foreign genes into plants genome via cassettes there by creating a new generation of plants with desired traits. Such plants possess improved seed quality, yield and resistance to pests and pathogens. The aim of this study is to screen for transgene in Cowpeas sold in Nigerian markets using molecular analysis. Five Improved varieties of Cowpea were obtained from IITA while local varieties were purchased from Terminus Market in Jos. All samples were screened for the presence of transgene via DNA extraction and PCR. Results shows the presence of transgene in MKT1, IT89KD and IT99KD, CAMV, NOS and VIP3BA respectively and none was found in local varieties.
