Schum.)(Kerala Agricultural University, Vellanikara, 2001) Karmarkar, S H; Keshavachandran, R; Nazeem, P A; Girija, DHolostemma ada-kodien, commonly known as adapathiyan is a laticeferous climber belonging to the family Asclepiadaceae. The root tubers of the plant are useful to cure various ailments of eye and many other human diseases. Due to the indiscriminate collection of root tubers, the plant population in the natural habitats has declined drastically and consequently it has been listed out as vulnerable and rare in the FRLHT red list of medicinal plants. The present study reports the hairy root induction in Holostemma useful in conservation of the plant and also to explore possibilities for in vitro production of the active chemicals in Holostemma, which would be a good alternative to meet its ever-increasing demand. The procedure for induction of hairy roots is given in detail.Item Detection of Ralstonia solanacearum race 3 causing bacterial wilt of solanaceous vegetables in Kerala, using random amplified polymorphic DNA (RAPD) analysis(Kerala Agricultural University, Vellanikara, 2003) Deepa, James; Girija, D; Sally K, Mathew; Nazeem, P A; Babu, T D; Sukumara Varma, ANine strains of Ralstonia solanacearum (Smith) Yabuuchi et al. isolated from bacterial wilt affected plants of brinjal, chilli and tomato in three different agroclimatic zones of Kerala were compared based on the utilization of carbohydrates, hypersensitivity reaction on capsicum leaves and RAPD analysis. Among these, six isolates were grouped into Biovar III and three, into Biovar IIIA. The isolates belonged to Races 1 and 3. RAPD analysis with 10 decamer primers revealed a high degree of polymorphism among the isolates. The primer OPF 8 yielded a unique band of 1.45 kb size for Race 3. This could be considered as a marker for rapid identification of Race 3 isolates of R. solanacearum.
