Over the last three decades, sporadic efforts have been made to develop regeneration
and transformation systems in cowpea (Vigna unguiculata L. Walp). This paper
reviews the progress made to date, including highlights of culture media and
explants used for regeneration and chimeric gene constructs employed in transformations.
Progress has been slow, mainly due to limited resources, since very few
laboratories have been involved. There is an urgent need for more focused and
consistent efforts to develop genotype, and tissue-culture dependent and independent
approaches for obtaining stable genetic transformation in cowpea
