Soybean belongs to the Leguminosae family having great nutritional value. It is considered to be a multipurpose crop used as food, feed, and fuel. Soybean as BNF (Biological Nitrogen Fixation) plant increases soil fertility through root nodule bacteria. Conventional breeding was used for improvement in crops in the past. But now scientists are working on soybean improvement through Genetic engineering (GE) to satisfy the global food demand. Genetic engineering methods i.e. gene silencing and transgenesis have reduced many risks and helped to increase soybean resilience. Recently, new plant breeding technologies (NBPTs) like transcription activator-like effector nucleases, zinc finger nucleases, and clustered regularly interspaced short palindromic repeats (CRISPR Cas9) appeared that are the basis for genetic improvement in soybean. These NBPTs proved beneficial in the improvement of soybean through precision genome engineering and gene functional characterization. These NBPTs have also covered the ethical and public acceptance problems about GE and transgenesis in soybean. In this review, we have provided a comprehensive note about stress resistance, nutritional enhancement of transgenic soybean, GE, and NBPTs, and their prospects.
