Abstract Passiflora xishuangbannaensis (Passifloraceae) is endemic to a few sites of Mengyang nature reserve in Yunnan, Xishuangbanna and less than 40 individuals have been recorded. Nine Passiflora species are endemic to Yunnan with most species occurring in South America, making P. xishuangbannaensis highly significant and emblematic to the conservation work in the region. This study is designed to provide the first protocol for in vitro organogenesis and plant regeneration for ex situ conservation and reintroduction for an Asian Passiflora species. Using internodes, petioles and tendrils we optimize calli formation and root elongation using several plant growth regulators, individually or in combination. We also assess the genetic stability of regenerated cells. The maximum callus induction and shoot bud differentiation were both achieved on half Murashige and Skoog basal medium supplemented with 4.44 µM 6-Benzylaminopurine and 1.08 µM 1-Naphthaleneacetic acid. The best rooting was achieved from 30 days old, regenerated shoots on half Murashige and Skoog basal medium supplemented with 1.08 µM 1-Naphthaleneacetic acid. Micropropagated plants were subjected to inter simple sequence repeat markers analyses. Collectively, 86 bands were generated from 6 primers of which 12 bands were polymorphic, showing genetic variation between the regenerated plantlets and the original plant. Response to plant growth regulators was more specific than most other studies using South American species, which could be explained by the morphological and physiological differences between South American and Asian Passiflora species

Leaf discs from 15 mutant clones of tomato were tested for their morphogenetic response in Murashige and Skoog medium supplemented with 12 combinations of the growth regulators napthaleneacetic acid (NAA) and benzylaminopurine (BA) and 4 combinations of NAA and zeatin. The results show that either callus, shoots, roots, or shoots and roots can be produced depending upon the hormone concentrations and ratios. Plants were regenerated from 12 of the 15 varieties tested.

Response of widely grown potato cv. Superior and newly developed cvs. Gui valley and Bora valley to plant growth regulators (PGRs) for direct plant regeneration from internode, leaf blade and petiole explants were investigated. The explants were cultured on a MS solid medium supplemented with different concentrations and combinations of 6-benzylaminopurine (BAP), 1-naphthaleneacetic acid (NAA), zeatin, indole-3-acetic acid (IAA) and gibberellic acid (GA3). Potato cv. Superior, regenerated direct shoot without callus and root formation on MS solid medium supplemented with BAP or zeatin, proliferous roots were produced on NAA or IAA supplemented medium and only some calli were produced on GA3 supplemented medium. The regeneration response varied with different concentrations of PGRs, singly and also in combinations. In the case of combined application of PGRs, the highest shoot regeneration (75.3%) and number of shoot per explant (11.5) and number of roots per explant (7.0) were obtained from the MS solid medium supplemented with zeatin (2 mg l-1), NAA (0.1 mg l-1) and GA3 0.1 mg l-1). Among the three types of explants evaluated, internodes produced the highest number of shoots and roots for both potato cvs. Gui valley and Bora valley, and petiole produced the least number of shoots and roots. The regenerated shoots were rooted in PGRs-free MS solid medium and successfully established under glasshouse condition. Leaf, flower, and tuber morphology were identical to in vitro control and mother plants in the same conditions. This optimized regeneration system can be used for rapid shoot proliferation and also for gene transformation.DOI: http://dx.doi.org/10.3126/njst.v12i0.6471 Nepal Journal of Science and Technology 12 (2011) 1-6
