Microprojectile bombardment mediated genetic transformation parameters have been standardized for seed derived callus of Eleusine coracana. Plasmid pCAMBIA 1381 harboring hygromycin phosphotransferase (hptII) as selectable marker gene and β-glucuronidase (gus A) as reporter gene, was used for the optimization of gene transfer conditions. The transient GUS(More)
BACKGROUND Biofuels derived from algae biomass and algae lipids might reduce dependence on fossil fuels. Existing analytical techniques need to facilitate rapid characterization of algal species by phenotyping hydrocarbon-related constituents. RESULTS In this study, we compared the hydrocarbon rich algae Botryococcus braunii against the photoautotrophic(More)
An efficient and reproducible protocol has been developed for in vitro propagation of Pithecellobium dulce (Roxb.) Benth (a multipurpose leguminous tree) from field grown nodal segments (axillary bud). Shoot bud induction occurred from nodal explants of 15-years-old tree on Murashige and Skoog (MS) basal medium supplemented with 4.4 μM 6-benzyladenine (BA)(More)
Expressed sequence tags (EST) are potential source for the development of genic microsatellite markers, gene discovery, comparative genomics, and other genomic studies. In the present study, 7630 ESTs were examined from NCBI for SSR identification and characterization. A total of 263 SSRs were identified with an average density of one SSR/4.2 kb (3.4%(More)
An efficient in vitro transformation and plant regeneration protocol was developed for Terminalia bellerica using cotyledonary node cultures. High-frequency shoot bud proliferation was obtained on medium with 6-benzyladenine. Significant improvements in plant regeneration occurred using elevated levels of CuSO4 and CoCl2. Rooting occurred on a half-strength(More)
The present study reports an efficient in vitro micropropagation protocol for a medicinally important tree, Terminalia bellerica Roxb. from nodal segments of a 30 years old tree. Nodal segments taken from the mature tree in March-April and cultured on half strength MS medium gave the best shoot bud proliferation response. Combinations of serial transfer(More)
Pithecellobium dulce has a huge repository of morphological and genetic diversity within the species which has been documented for further tree research and breeding programmes. A total of 40 accessions of a multipurpose leguminous tree, Pithecellobium dulce, differing in morphological and phenological characteristics was collected from different locations(More)
Plant regeneration from immature embryos of 15 Indian barley genotypes (Hordeum vulgare L.) was examined. Highest percent callus induction and number of regenerated plantlets were obtained in cultivars BL 2 (94.4 %; 12.1), RD 2668 (92.6 %; 9.1) and RD 2552 (90.8 %; 7.8). The highly responding cultivar BL 2 was selected for further development of(More)
Expressed sequence tags (ESTs) are important resource for gene discovery, gene expression and its regulation, molecular marker development, and comparative genomics. We procured 10000 ESTs and analyzed 267 EST-SSRs markers through computational approach. The average density was one SSR/10.45 kb or 6.4% frequency, wherein trinucleotide repeats (66.74%) were(More)
An efficient Agrobacterium-mediated genetic transformation protocol has been developed for Indian winter barley. Several parameters affecting Agrobacterium-mediated gene delivery were investigated and optimized. These include use of acetosyringone, surfactants in the infection medium, antinecrotic treatment of explants and heat and centrifugation(More)
