Virus Diseases in Man Animal and Plant

in 15 per cent of these cases. The internal carotid artery was the site of the aneurysm in 35.4 per cent of the patients, while the remainder were almost equally divided between (1) the anterior cerebral and anterior communicating arteries, (2) the middle cerebral, and (3) the basilar and vertebral arteries. The aneurysms are classified into three categories; mycotic, 6; arteriosclerotic, 22; a...

Plant Resistance to Virus Diseases through Genetic Engineering: Can a Similar Approach Control Plant-parasitic Nematodes?

Genetically engineered resistance against plant virus diseases has been achieved by transforming plants with gene constructs that encode viral sequences. Several successful field trials of virus-resistant transgenic plants have been carried out. Specific features of virus infection make it possible to interfere with different steps of the infection and disease cycle by accumulating products of ...

Plant Disorders and Diseases

A plant disorder is defined as any abnormal plant growth or development. The affected plant does not live up to the normal expectations; it is incapable of carrying out its normal physiological functions to the best of its genetic potential. There are almost an unlimited number of factors that can have a negative affect plants. Disorders can be broken down into two main categories, abiotic diso...

Biological control of plant diseases

Bacteriophages and Bacterial Plant Diseases

Losses in crop yields due to disease need to be reduced in order to meet increasing global food demands associated with growth in the human population. There is a well-recognized need to develop new environmentally friendly control strategies to combat bacterial crop disease. Current control measures involving the use of traditional chemicals or antibiotics are losing their efficacy due to the ...
