Stevia Rebaudiana Bertoni's Economical Micropropagation and Evaluation of in Vitro Cultures to Enhance Steviol Glycosides

Ronagthon Garam W

The leaves of Stevia rebaudiana Bertoni yield a significant quantity of zero-calorie sweetener that is 300 times sweeter than sucrose. The plant S. rebaudiana is incompatible with itself and only produces a few seeds that germinate slowly. The purpose of this study was to develop a cost-effective method for S. rebaudiana micropropagation. By dispensing with the establishing society medium in this review, the creation cost has diminished by roughly 34%. The proportion of stevioside to rebaudioside A, the primary steviol glycoside, determined the sensory characteristics. Using 0.02 mg/l NAA and 0.05 mg/l BAP, this study produced S. rebaudiana tissue with a rebaudioside A to stevioside ratio of 3.76 in a bioreactor. This plant tissue had a better flavor than the shoots that were grown in the field. Stevioside was more abundant than rebaudioside A in cell suspension, but there was no change in steviol glycosides. Moreover, the bristly root development conditions were additionally improved in this review, by utilizing A4, ATCC15834, and LBA9402 kinds of Agrobacterium rhizogenes for leaf and stem explants utilizing two change techniques including co-culture and infusion. The ATCC15834 strain and injection method produced the highest transformation rate (60%) in leaf tissue. In previous studies, this transformation rate was not observed. Stevioside and rebaudioside A were found in some hairy roots, and the amount of rebaudioside A was higher than that of stevioside in two of the roots.

The utilization of hereditary designing and biotechnology could impressively build the quality and amount of steviol glycosides and work on the flavor of S. rebaudiana.
