Changing spectrum for crop plants

Biofortification of Crop Plants

Salt resistant crop plants.

Soil salinity is a major constraint to agriculture. To improve salinity tolerance of crops, various traits can be incorporated, including ion exclusion, osmotic tolerance and tissue tolerance. We review the roles of a range of genes involved in salt tolerance traits. Different tissues and cells are adapted for specific and often diverse function, so it is important to express the genes in speci...

Changing Spectrum of Typhoid

To determine the changing spectrum of typhoid fever, a study was conducted on 240 cases of typhoid fever, admitted over a period of 4 years. The classical ‘Stepladder fever’ and ‘relative bradycardia’ were less commonly seen. Presentation as hepatitis, psychosis, meningism, myocarditis, polyneuropathy and diarrhoea were encountered in a small number of patients. Reversible proximal myopathy occ...

Developing heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops

Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...

Engineering Cold Stress Tolerance in Crop Plants

Plants respond with changes in their pattern of gene expression and protein products when exposed to low temperatures. Thus ability to adapt has an impact on the distribution and survival of the plant, and on crop yields. Many species of tropical or subtropical origin are injured or killed by non-freezing low temperatures, and exhibit various symptoms of chilling injury such as chlorosis, necro...
