Nitrogen (N) remobilization from reserves to sinks is essential for seedling establishment and seed production. Cytosolic glutamine synthetase (GS1) is up-regulated during both seed germination and seed filling in plants. However, the specific roles of the individual GS1 isogenes with respect to N remobilization, early seedling vigour, and final seed productivity are not known. In this study, i...

Co-aggregation was attempted in Azorhizobium caulinodans ORS-571 with other agriculturally important microorganisms such as Azospirillum brasilense MTCC-125, Azotobacter chroococcum MTCC-446, Bacillus megatherium MTCC-3353, and Pseudomonas fl uorescens MTCC-4828 to develop coaggregates with multiple benefi ts using seed powders of diff erent plants viz., Moringa oleifera, Strychnos potatorum an...

The non-enzymatic modifications of proteins through Amadori and Maillard reactions play an important role in the loss of seed viability during storage. In the present study, the contribution of sugar hydrolysis and lipid peroxidation to Amadori and Maillard reactions, and to seed deterioration was investigated in mung-bean (Vigna radiata Wilczek). The contents of glucose and lipid peroxidation ...

Bacillus subtilis strain IH7 was isolated from the rhizosphere of Tunisian healthy plants and selected for its antimicrobial activities against bacteria and fungi. This strain produced a novel antimicrobial peptide (bacteriocin) called Bac IH7. The pure bacteriocin was obtained after precipitation by ammonium sulphate, chromatography on Sephadex G-25 and C18 reverse-phase HPLC. The SDS-PAGE ana...

A study had been conducted in black gram to observe the effect of different seed invigoration treatments with bio-priming for germination, seedling growing and vigour. The variety i.e., Uttara, was selected treated control (T1); Seeds soaked distilled water/ hydropriming (T2); Rhizobium leguminosarum 10% (T3); 15% (T4); 20% (T5); 25% (T6); 30% (T7) respectively. Treated seeds were grown glass p...

An experiment was conducted to evaluate and compare the seed extraction methods on physiological quality of eggplant seed in Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University during 2012-2013 growing season. Full ripen standard size fruits (60 DAA) of eggplant var. BARI begun-5 (round shape) and BARI begun-8 (long shape) were harvested and kept in ambient c...
