Abstract

Plant biotechnology has evolved more than three decades ago, and it entails a wide range of technologies applied in a range of techniques intended to enhance plant growth and productivity of valuable crops, such as soybean . About one-third of the world’s edible oils and two-third of protein meals are derived from such improved crop varieties. The use of genetic engineering for the improvement of soybean has promised higher yield , better seed quality, lower pesticides/fertilizers applications, affordable soy-based products and the potential to rapidly raise economic gains in developing countries. Soybean contains 35–52, 14–24, 34–41 and 7–11% of seed compositional protein, oil, carbohydrates and fibre respectively, than most of the grain legumes. However, the rise to a host of technology concerns and negative perceptions against plant transformation techniques used for soybean improvement, like the recombinant DNA technology is overwhelming. The tool is said to raise serious concerns despite the numerous benefits associated with it, such as; improved plant nutritional content, wider genetic characterization and high tolerance to pests diseases as well as abiotic constraints such as drought.

Therefore, the current review summarizes research on challenges facing soybean genetic improvement, the extent of this crop’s vulnerability against drought stress , approaches used to improve growth and productivity, especially in combating food insecurity, and interrogate potential opportunities as well as scepticism surrounding the evolution of biotechnology with respect to general consumer perceptions and agribusiness.
