The main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. We were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. If such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. In addi...

The genetics of resistance to disease is an area of great interest in agriculturally important plant and animal species. Selective breeding for resistance to pathogens in plants, animals and insects has demonstrated that resistance and susceptibility to pathogens are controlled by both genetic and environmental factors. The immune loci causally involved in susceptibility and resistance to disea...

a recently published article describing the draft genome of erwiniamallotivora bt-mardi (1), the causal pathogen of papaya dieback infection in peninsular malaysia, hassignificant potential to overcome and reduce the effect of this vulnerable crop (2). the authors found that the draft genome sequenceis approximately 4824 kbp and the g+c content of the genomewas 52-54%, which is very similarto t...

Deployment of host resistance remains the most cost effective strategy for management of foliar and grain diseases, especially for resource constrained farmers. There is paucity of information on dual resistance in sorghum to both diseases. The objective of this study was to identify SSR markers associated with anthracnose and TLB resistance in sorghum for future use in markers assisted introgr...

Indigenous plant remedies are widely used in the treatment of variety of disorders because these products are safe, widely available at low cost, and easy to access. Developing countries are severely threatened by amoebic diseases mainly caused by Entamoeba histolytica. Drugs available have been reported to be mutagenic so an alternate source of medicines is highly required. Plant extracts have...
