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
