In Vitro Biotechnological Progressions in Pueraria tuberosa (Willd.) DC.

Pueraria tuberosa (Willd.) DC., belonging to the family Fabaceae, is in great demand in Ayurveda because of its healing properties against weakness, diabetes, and fertility disorder. Indian kudzu tubers are rich in isoflavonoids like puerarin, daidzein, genistein, and genistin. It also possesses phytosterols, terpenes, and other phenolic compounds. The seeds of this plant have a low regeneration capacity, while the tuber takes a major role in propagation. P. tuberosa revives during the rainy season, and due to the substantial use of tuber for its medicinal properties, it is doubtful that it may be included in the endangered list. This review covers the problems associated with germination and the alternative techniques of in vitro regeneration to date and describes the future prospects of P. tuberosa. There is a need for the most advanced techniques of tissue culture with plant growth regulators and their implementation to successfully revive the plants in both in vitro and ex vitro conditions.
