Abstract

Viruses use host resources to support their own reproduction and dissemination, so it is widely bilieved that virus infections are harmful to the host. Plant virus causes various types of disease and produce symptoms such as ringspot, mosaic pattern development, leaf yellowing and distortion as well as deformed growth. Temperature is one of the most important environmental factors that effect host-virus interaction. Outbreak of viral disease is frequently associated with the ambient temperature required for host development.

The effect of temperature and virus on plant growth and productivity is well documented. But studies showing the effect of both on plant growth are only a few. So aim of my study is "Literature mining and compilation of heat and virus combined stress data to understand combined stress tolerance in plant". Till date eight studies have been reported showing the combined effect of heat and virus stress on plant, and out of which seven studies have been reported showing negative effect on plant. There is only one study which reported that high temperature suppressed the symptom severity and lowered the disease incidence.
