Abstract
Bacopa monnieri (L.), a highly endangered miracle medicinal herb with global interest, is one of the popular ancient Indian ayurvedic plants. With ever increasing demand for Bacopa based formulations in pharmaceutical industries, there is a need to preserve the stocks of the plant through biotechnological approaches. Randomly amplified polymorphic DNA (RAPD) fingerprinting approach was applied to analyze the genetic stability of 19 different B.monnieri plants randomly selected after micropropagation, regrowth from alginate encapsulated uninodal cuttings (before and after storage at 4°C) and hardening with the mother plant (wild type). 16 arbitrary decamer primers amplified a total of 334 reproducible distinct DNA fragments ranging from 180 to 1,500 bp, of which 262 (78.4%) were monomorphic and the rest (21.5%) were polymorphic with an average of 20.8 bands per primer. The extent of polymorphism was low to moderate. Primers OPAK 14, OPM 15 and OPD 13 generated 69, 46 and 42% polymorphic patterns. Primers OPA 04, OPU 13 and OPD 08 generated 100% monomorphic pattern. Similarity matrix based on Jaccard’s coefficient revealed that pair wise values between the wild type and its analyzed plants ranged from 0.00 to 0.92 and among the micropropagated, synthetic seed derived and hardened plants, the range of genetic distance is from 0.67 to 0.92. Unweighted pair group method with arithmetic averages cluster analysis resulted in one loose group of the wild type with three subgroups. The present study paves the way for the identification and maintenance of genetically uniform B. monnieri plants micropropagated in the lab, plants regrown from synthetic seeds and hardened in the field.
