A complete and efficient protocol was developed for in vitro callus induction, somatic embryogenesis and plantlet regeneration from in vivo nodal and internodal segments and shoot tips of sissoo (Dalbergia sissoo Roxb.). The highest percentage of callus induction (100%) was achieved from nodal segment on MS medium supplemented with 2.0 mg/1 BAP + 0.5 mg/1 NAA. This combination also produced highest fresh weight (5.4 g.) of callus per culture and produced friable green callus. The highest number of shoots (2.4) per explant was recorded on MS medium supplemented with 1.5 mg/1 BAP + 0.5 mg/1 IAA for internode segment. The maximum number of roots (5.1)per shoot was observed in the MS medium having 1.0 mg/1 IBA + 2.0 mg/1 NAA. The well Rooted plantlets were acclimatized and successfully established into soil in the natural condition where 60% plantlets were survived.

This study aims to investigate whether the in vitro-cultured L. pumila var. alata has higher antioxidant activity than its wild plant. An 8-week-old L. pumila var. alata nodal segment and leaf explants were cultured onto Murashige and Skoog (MS) medium supplemented with various cytokinins (zeatin, kinetin, and 6-benzylaminopurine (BAP)) for shoot multiplication and auxins (2,4-dichlorophenoxyacetic acid (2,4-D) and picloram) for callus induction, respectively. The results showed that 2 mg/L zeatin produced the optimal results for shoot and leaf development, and 0.5 mg/L 2,4-D produced the highest callus induction results (60%). After this, 0.5 mg/L 2,4-D was combined with 0.25 mg/L cytokinins and supplemented to the MS medium. The optimal results for callus induction (100%) with yellowish to greenish and compact texture were obtained using 0.5 mg/L 2,4-D combined with 0.25 mg/L zeatin. Leaves obtained from in vitro plantlets and wild plants as well as callus were extracted and analyzed for their antioxidant activities (DPPH and FRAP methods) and polyphenolic properties (total flavonoid and total phenolic content). When compared with leaf extracts of in vitro plantlets and wild plants of L. pumila var. alata, the callus extract displayed significantly higher antioxidant activities and total phenolic and flavonoid content. Hence, callus culture potentially can be adapted for antioxidant and polyphenolic production to satisfy pharmaceutical and nutraceutical needs while conserving wild L. pumila var. alata.

Dalbergia sissoo Roxb. ex DC. (Sissoo) is a native forest tree species in Pakistan. Many ecological and economical uses are associated with this premier timber species, but dieback disease is of major concern. The objective of this study was to develop a protocol for in vitro regeneration of Sissoo that could serve as target material for genetic transformation, in order to improve this species. Callus formation and plantlet regeneration was achieved by culturing cotyledons, immature seeds, and mature embryos on a modified Murashige and Skoog (1962) (MS) medium supplemented with plant growth regulators. Callus induction medium containing 2.71 ?M 2, 4-dichlorophenoxyacetic acid (2,4-D) and 0.93 ?M kinetin produced better callus on all explants tested compared to other treatments, such as 8.88 ?M 6-benzylaminopurine (BA) and 2.69 ?M ?-naphthalene acetic acid (NAA), or 2.71 ?M 2, 4-D and 2.69 ?M NAA. Shoot regeneration was best on MS medium containing 1.4 ?M NAA and 8.88 ?M BA compared to other treatments, such as 1.4 ?M NAA and 9.9 ?M kinetin, or 2.86 ?M indole-3-acetic acid and 8.88 ?M BA. Murashige and Skoog medium containing 1.4 NAA ?M and 8.88 ?M BA was better in general for regeneration regardless of callus induction medium and the type of explant used. Rooting was best on half-strength MS medium with 7.35 ?M indole-3-butyric acid. Regenerated plantlets were acclimatized for plantation in the field. Preliminary genetic transformation potential of D. sissoo was evaluated by particle bombardment of callus explants with a pUbiGus vector. The bombarded tissue showed transient Gus activity 1week after bombardment. Transformation of this woody tree is possible provided excellent regeneration protocols. The best combination for regeneration explained in this study is one of such protocols.

The experiment was conducted during May to December 2008 in the Biotechnology Laboratory of Bangladesh Agricultural University, Mymensingh to observe the callus induction, regeneration potentiality and to establish a suitable in vitro plantlet regeneration protocol of Corchorus olitorius. MS medium supplemented with different phytohormone concentrations and combinations were used to observe the callus induction, shoot regeneration and root formation ability of the cotyledon with attached petiole derived explant of three genotypes viz. O-9897, O-72 and OM-1. The highest callus induction (92.85%) was observed in O-9897 followed by O-72 (82.14%) in the MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA. Genotype O-9897 in MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA produced the highest percentage of shoot regenerants (83.33%) followed by O-72 (75.00%) in the media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA. The root formation from regenerants was the best on halfstrength of MS media supplemented with 0.6 mg/L IBA in genotype O-9897 (45.00%). The in vitro regenerated plantlets from the genotypes O-9897 could be established in the field. Therefore, the genotypes O-9897 of C. olitorius in MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA could be used for callus induction and shoot regeneration.

In vitro study was carried out in an important medicinal plant Tinospora cordifolia (Willd.) Miers belonging to the family: Menispermaceae. Vegetative parts such as stem, leaf and nodal explants were excised from an elite in vivo grown mature plant and thereafter cultured on Murashige-Skoog (MS) medium supplemented with different hormonal concentrations for callus induction and organogenesis. Callus formation occurred from nodal segments, leaf and inter-node explants when planted on different combinations of hormones. Tinospora cordifolia showed response for in vitro shoot growth from the nodal segment. The best shoot growth was observed on MS medium supplemented with kinetin (1.5 mg/l). Similarly, the best result for root induction was obtained on MS medium supplemented with 6-benzylaminopurine (1.0 mg/l) and naphthaleneacetic acid (2.5 mg/l).

Anther of five varieties of Brassica species, namely BARI Shariaha-7, Tori-7, Agrani, Daulat and Safal were cultured in vitro to observe their regeneration potentiality. Different concentrations and combinations of growth regulators were supplemented in MS medium. The range of callus induction was 12.50-87.50 %. Maximum callus induction (75.00%) was observed on MS +4 mg/L 2, 4-D + 1.0 mg/L BAP. Among the genotypes, BARI Sharisha-7 showed the highest percentage of callus induction (60.42%). Among the treatments, highest percentage of shoot regeneration (75.00%) was observed on MS + 4 mg/L BAP + 1.0 mg/L NAA. BARI Sharisha-7 also showed the highest rate of plant regeneration (66.67%). Root induction was highest (75%) on half strength MS medium supplemented with 1.0 mg/L IBA and 0.5 mg/L NAA. The plantlets with sufficient roots thus obtained were transferred successfully to plastic pots and subsequently to the field. BARI Sharisha-7 and Tori-7 survived easily in the pots as well as in the field but Safal was very poor in survivability both in the pots and in the field.

An experiment on the effect of sucrose and mannitol on leave induced callus of Catharanthus roseus was conducted from February 2011 to May 2012. Callus induction was achieved by culturing leaves of the plant on MS medium supplemented with 0.5 mg /L 2,4-D and 1mg / L Kin, The best medium to maintain callus was on MS medium modified with 0.5 mg /L 2,4-D and 1.5 mg / L Kin. when different levels were added to MS medium for each Mannitol 0, 6000 ,8000 ,10000 mg /L and Sucrose 40, 60 ,80, 100 g /L in split experimental and control treatment was MS medium supplemented with 30 g/L sucrose. The results showed that medium supplemented with 100 gL of sucrose gave the highest quantity of Ajmalicine 32.27 µg/100 mg fresh weight of callus,as well as medium supplemented with 8000 mgL of Mannitol gave the highest value of Ajmalicine 120.19 µg/100 mg fresh weight of callus. The concentrations of Ajmalicine, derived from the leaves of the plants grown in pot, were lowest than the concentrations produced by the callus grown in vitro it was 0.047 µg/100 fresh weight of the leaves.
