A rapid micro propagation and acclimatization response of two different varieties of sugarcane Co86032 and CoN 04131(Saccharum officinarum L.) was obtained in this study. The shoot apical meristem of different sizes wascultured on Murashige and Skoog medium supplemented with different concentrations and combinations of ben-zylaminopurine and kinetin either alone or in combination with each other alongwith GA3. Best shoot formation response in Co 86032 was obtained on MS medium containing 1.5mg/l BAP while in CoN 04131 the combination of 0.5 mg/l BAP with 0.25 mg/l Kinetin showed best shoot formation response from apical meristem. Meristem of 3.0 mm size proved to be the best size for micropropagation of sugarcane. Excellent multiplication response of In vitro formed shoots was obtained when the concentration of BAP was decreased to 1.0 mg/l in Co 86032and 0.25 mg/l BAP and Kin in CoN 04131 (i.e. 0.25 mg/lBAP + 0.25 mg/l Kinetin. MS medium containing 1.0 mg/l NAA and 2.0 mg/l IBA showed 100% rooting response of In vitro regenerated shoots of both the varieties of sugarcane within eight days of inoculation. Best hardening response was obtained in sand+ soil + pressmud (1:1:1) media.

In vitro propagation has become an effective practice for large-scale production of strawberry plants. The objective of this study was to evaluate the hyperhydricity and the multiplication capacity of two strawberry varieties (Fragaria x ananassa Duch. 'Dover' and 'Burkley') propagated in vitro. Plants maintained in MS medium supplemented with 1.0 mg L-1 BA were individualized and transferred to the same medium solidified with Agar (6.5 g L-1) or Phytagel® (2.5 g L-1) and BA at different concentrations (0; 0.5; 1.0; 2.0 and 3.0 mg L-1). Biochemical and anatomical analyses were carried out, as well as the analysis of the morphological hyperhydricity characteristics. The analysis of data showed: a) the increase in cytokinin concentration increased hyperhydricity frequency in both varieties; b) at concentrations up to 2.0 mg L-1 BA, the replacement of Agar by Phytagel® induced a higher formation of hyperhydric shoots; and c) the addition of BA induced oxidative stress, which is characterized by increased antioxidant activity and lipid peroxidation, as well as alterations at the cellular level, such as malformation of stomata and epidermal cells. In conclusion, the culture medium containing 0.5 mg L-1 BA solidified with Agar provided lower hyperhydricity percentages in association with higher rates of shoot proliferation in strawberry.

Micropropagation is a vegetative propagation conducted under controlled and aseptic conditions in the microenvironment of the culture vessel, which have the all growth requirements of a plant in the natural conditions. Recently different techniques of propagation have been developed which could facilitate large scale production of plants and for the improvement of the species. An overview on the in vitro propagation via meristem culture, callus culture and protoplast culture etc. are presented here. Today micropropagation techniques are applied in order to produce large numbers of new high-quality plants in a relatively short time and space, in low cost and can also be preserved.

Banana is an important fruit crop belongs to the family Musaceae. This has more demand for it multifarious uses like food, medicinal as well as industrial values. The present study was carried out to develop micropropagation protocol for large scale production of banana cv. Grand naine using sucker explant. Sucker explants were inoculated on Murashige and Skoog’s (1962) (MS) basal medium and MS basal medium supplemented with different types and concentrations and combination of plant growth regulators. Highest mean number of shoots (10.2) per explant having mean shoot length 5.2 cm was observed on MS medium supplemented with 4.0 mg/L BA, 2.0 mg/L Z, 1.0 mg/L NAA, and 3.0 mg/L ADS. For large scale production of shoot, in vitro regenerated shoots were harvested, cut into small pieces and inoculated on the optimum medium for multiple shoot proliferation. In this way, more than thousand numbers of in vitro shoots were regenerated from a single explant at six month of culture. In vitro regenerated shoots were excised and rooted on ½ MS medium supplemented with 1.0 mg/L IBA. Finally in vitro regenerated plants were acclimatized and subsequently transferred to field with zero mortality. This protocol helps to meet the demand of the farmers.

Bulbous structures consisting of meristematic clumps (designated “shoot primordia”) were induced from a meristematic culture of a hybrid statice (Limonium altaica Mill. × L. caspium Mill., cv. Blue Symphonet). The shoot tips were cultured in 25 mL of liquid 1/2 Murashige & Skoog (MS) medium supplemented with 0.44 μm BA and 0.054 μm NAA and 3% sucrose at pH 5.8 by vertically shaking at 2 rpm on rotating stages (1 m in diameter) at 25 °C. One month after inoculation of shoot tips, numerous small globular structures were formed and propagated vegetatively at a high rate following subculture. Segments of shoot primordia had developed into plantlets 2 weeks after transfer to solidified 1/2 MS medium supplemented with 0.44 μm BA and 1% sucrose. Plantlets successfully acclimated and grew into normal plants in a greenhouse. Cold-hardened, precultured small segments of shoot primordia were successfully cryopreserved in liquid N by vitrification. Vitrified and warmed segments plated on solidified 1/2 MS medium produced shoots about 21 d after plating. Cultured masses of shoot primordia appear promising for large-scale production and cryopreservation of annual and biennial statice. Chemical names used: 6-benzyladenine (BA); 1-naphthaleneacetic acid (NAA).

Abstract Conventional vegetative propagation of sugarcane generally has low multiplication rate and allows distribution of diseases. Micropropagation is the only practical means of achieving rapid, large-scale production of disease-free quality planting material. Experiments on shoot tip culture initiation and shoot multiplication were laid out in completely randomized design with 2x3x3 and 4x5x3 factorial treatment arrangements respectively. Data was subjected to analysis of variance (ANOVA) and significant means were separated using Duncan's multiple range tests. With regard to shoot multiplication, genotype Q200 showed a maximum of 13.59 shoots per explant with 5.83cm shoot length on a medium fortified with 2 mg/l BAP alone, while genotype Q217 produced a maximum of 15.28 shoots per explant with 5.37cm mean shoot length on a medium supplied with 2.0 mg/l BAP and 0.25 mg/l kinetin. Likewise, Co-0238 produced maximum of 13.56 shoots per explant with mean shoot length 6.50 cm on medium fortified with 1.5 mg/l BAP + 0.5mg/l kinetin

A recombinant plasmid containing a metallothionein promoter-polyoma middle T cDNA fusion was constructed and used to transfect NIH 3T3 cells. Transformed cells expressing middle T were injected into nude mice. Within 3 weeks, each mouse produced tumors containing middle T equivalent to that in 250 to 1,000 100-mm dishes of polyomavirus-infected cells. This middle T, partially purified by immunoaffinity chromatography, retained activity as measured by its ability to be phosphorylated in vitro. The combined approach of fusing strong promoters to genes of interest and utilizing nude mice to grow large quantities of cells expressing the gene provides a quick, inexpensive alternative to other expression systems.

Biphasic Fermentation

Formulation of effective and environmental friendly bioherbicides depends on the type of fermentation medium used for the production of phytotoxic metabolites. The effect of biomass, colony forming unit and the phytotoxic metabolite produced from the biphasic fermentation was carried out, while the phytotoxic metabolite was  tested in vivo and in-vitro on Echinochola crus-galli and dicotyledonous Chromolaena odorata. The mutant strain of Lasiodiplodia pseudotheobromae C1136 (Lp90) produced the highest amount of conidia and the largest necrotic area on the two tested weeds when compared to its wild strain in the different biphasic media combinations. The study revealed that the biphasic system containing PDB + rice produced the highest bioherbicidal activities. Therefore, the phytotoxic metabolites from strain C1136 are suggested for large scale production of bioherbicides for the management of weeds in conventional farming to improve yield and enhance food security.
