The purpose of the present study was to develop effective methods for callus induction, shoot regeneration, and rooting for Parasponia andersonii. Leaf explants of P. andersonii were placed on Lloyd and McCown’s (WPM) medium supplemented with various concentrations of TDZ and NAA for callus induction. Callus induction was observed on media containing 0.1 - 0.2 mg/l TDZ with 0.05 mg/l NAA. Maximum shoot regeneration was observed when the calluses were cultured on MS supplemented with TDZ and IBA. Shoots cultured on WPM medium supplemented with 0.5 mg/l IBA had the maximum rooting percentage (100) in 3 weeks. Rooted plants were transplanted to a potting mixture containing vermiculite (50%) and peat (50%) (v/v). After 2 months, more than 20% of plants survived and were transferred to the greenhouse. Thus, a new effective method has been developed for P. andersonii micropropagation that can be used in studies of plant-Rhizobium symbiosis and for the generation of transgenic Parasponia plants.Plant Tissue Cult. & Biotech. 28(1): 45-55, 2018 (June)

Lychnis cognate Maxim and Lychnis fulgens Fish. Ex Spreng are two valued ornamental plants in Korea. Soaking of seeds in GA3 solution remarkably promoted germination up to 60%, but the control (0 mg/l) was not effective (> 5%). To select an adequate temperature for seed germination, seeds, previously soaked in a 1000 mg/l GA3 for 24 hrs, were incubated at 15, 20, 25, and 30°C. Seed germination of over 20% was obtained at 15, 20, and 25°C, but only 10% at 30°C. These results indicate that the seeds of L. cognate and L. fulgens are in a such dormant state that they hardly germinate even by dormancy breaker (GA3) and low (15 ? 25°C) temperature treatment. The highest callus induction was observed in the leaf explants of the seedlings on MS containing specific concentrations of 3.0 mg/l BA and 1.0 mg/l NAA. The adventitious shoot was formed < 90% of calli on 1/2 WPM medium. The height of in vitro propagated plantlet was no different media used for regeneration. This in vitro propagation protocol should be useful for conservation of endangered and ornamental plant.Plant Tissue Cult. & Biotech. 25(1): 1-12, 2015 (June)

The experiment was conducted to investigate the performance of three different genotypes (BARI Sarisha-6, BARI Sarisha-8, and BARI Sarisha-11) in two different media viz., MS and B5 with different concentrations of phytohormone (2, 4-D) for callus induction from uninucleate stage anthers of Brassica and subsequent plant regeneration in MS media with different concentrations of phytohormone (BAP and NAA). Among the genotypes, BARI Sarisha-8 showed the best performance for all the parameters of callus induction. The performance of BARI Sarisha-6 was poor compared to others. Maximum rate of callus induction (%) was observed in MS + 0.5 mg/L 2, 4-D followed by B5 + 0.5 mg/L 2,4-D. The media combination MS + 1.0 mg/L BAP 0.3 mg/L 2,4-D showed the best performance for maintenance of calli. Significant variations were observed among the genotypes and media composition for shoot regeneration. Among the genotypes, BARI Sarisha-8 showed the best performance for shoot regeneration followed by BARJ Sarisha-l1. The genotype BARI Sarisha-8 produced higher percent of shoots/calli and required minimum days for shoot initiation. Higher percent calli without shoot were produced by the genotype BARI Sarisha-6. The media combination MS + 2.0 mg/L BAP + 0.5 mg/L NAA showed the best performance for shoot regeneration and required maximum days for shoot initiation.

The present study was undertaken to establish a protocol for in vitro callusing of three Jatropha accessions, namely Metema, Adami Tulu and Shewa Robit from leaf explants. The medium supplemented with combination of 4.44 μM BAP and 4.52 μM 2,4-D resulted in maximum percentage of callus (100%) formed for all accessions. The maximum shoot regeneration (66.67%) from callus with 10.13 number of shoot was obtained from Shewa Robit in MS medum fortified with TDZ (2.27 μM ) and IBA (0.49 μM ). The presence of TDZ in the shoot regeneration medium has greater influence on the induction of adventitious shoot buds, whereas MS supplemented with BAP alone and combination with IBA did not induce shoot regeneration from callus culture. The results obtained in the present study would facilitate the high callus induction and regeneration responses in Jatropha for its improvement using biotechnological tools.

Efficient plant regeneration could be obtained from the derooted nodal segments of Centella asiatica with stole buds as the explant, when cultured on MS medium supplemented with BAP (10 ppm)+NAA(2ppm). Both callus and regeneration occurred simultaneously on the same medium. Profuse rooting were obtain on MS medium fortified with NAA (2ppm) from leaf explants. Shoot and root proliferation were observed on the medium supplemented with BAP(5 ppm)and NAA (2 ppm) through subculture. Mass propagation of plantlets were obtained through invitro culture.

This study was undertaken to establish a regeneration protocol for two scented indica rice varieties, namely Pusa Basmati1 and Kalanamak. Callus culture in Pusa Basmati1 was initiated in MS containing 2.0 mg/l of 2,4-D. Optimum requirement of growth hormones for callus induction in Kalanamak was 1.5 mg/l of 2,4-D supplemented with 0.1 mg/l each of NAA and BAP in MS. Shoot regeneration in Pusa Basmati1 initiated in MS containing 2.0 mg/l BAP, 0.5 mg/l each of NAA and Kn. There was no shoot initiation in MS with same composition in Kalanamak. The shoot regeneration was successfully initiated and achieved in Dl medium supplemented with 2.0 mg/l BAP, 0.2 mg/l each of IAA, NAA and Kn, 500 mg/l each of proline and glutamine and 800 mg/l casein hydrolysate. The calli derived from mature seed embryo produced fertile green plants. The plants were successfully transferred to field with normal flowering.
