Citrus tristeza virus changes the biochemical and physiological status of infected Mexican lime plants

Reactions that occur when the plant is subjected to Citrus tristeza virus infection often results in triggering numerous defence mechanisms to fight the infection.To understand such kind of infection, changes in nutrient status, total proteins, enzyme activities involved in scavenging stressed conditions, photosynthetic and transpiration rates, membrane permeability and relative water content were analysed in lime plants inoculated with different CTV strains and healthy plants.Clear physiological changes were found between infected and non-infected plants but none between the plants inoculated with different CTV strains. Results suggest that the most of the defence mechanism investigated here were supressed due to the continuous and long-term pressure of CTV biotic stress
