Regeneration and assessment of genetic fidelity of the endangered tree Moringa peregrina (Forsk.) Fiori using Inter Simple Sequence Repeat (ISSR).

Moringa peregrinais an endangered species of Moringaceae.M. peregrinais a multipurpose tree with a wide variety of potential uses including its medicinal activity. In our study, a rapid and efficient micropropagation protocol for M. peregrina has been established. In vitro germinated seedlings were cultured on Murashige and Skoog (MS) medium supplemented with different levels of either 6-benzyladenine (BA) or kinetin (Kin). The maximum shoot proliferation of 6.5 shoots per explant with 100 % shoot proliferation rate was observed on MS medium supplemented with 1.0 mg/l BA. On the other hand, MS medium supplemented with 1 mg/l indole-3-butyric acid (IBA) resulted in the maximum number of roots. Micropropagated plants were successfully acclimatized. Genetic stability of micropropagated plants was assessed using Inter-Simple Sequence Repeat (ISSR). The amplification products were monomorphic in all in vitro grown plants. No polymorphism was detected indicating the genetic integrity of in vitro propagated plants. This micropropagation protocol could be useful for raising genetically uniform plants for plant propagation and commercial cultivation.
