Agar affects the efficient invitro regeneration in tomato (Solanum lycopersicum L.)

Establishment of an efficient tissue culture protocol is an essential prerequisite in harnessing the advantage of cell and tissue culture for genetic improvement. The present study deals with the effect of desiccation created in the culture media i.e. in MS media supplemented with BAP (2.0 mgl-1) and kin (1.0 mgl-1) by increasing the concentrations of agar (0.8, 1.2, 1.6 and 2.0 percent). The observations were recorded on...

Bacterial enzyme, sulphate, nitrate and ultimate latex paint biodegradation

The role of bacterial extracted enzyme, nitrate and sulpahte mobilization in latex paint degradation was investigated. The result revealed that degradation rate ie paint utilization was better enhanced by the presence of sulphate (SO42-) than nitrate (NO3-) though at no significant level (p>0.01). However, Bacillus species exceptionally mobilized nitrate (19.4mm) than sulphate (18.9mm). The overall mobilization rate for...

Recombination fraction and genetic linkage among key disease resistance genes (Co-42/Phg-2 and Co-5/“P.ult”) in common bean

Anthracnose (Colletotrichum lindemuthianum), Angular leaf spot (Pseudocercospora griseola) and Pythium ultimum are important pathogens affecting common bean production in the tropics. A promising strategy to develop superior genotypes to manage these diseases consists of combining several resistance (R) genes into one cultivar through pyramiding using molecular markers. The aim of the study was to determine genetic linkage...
