Biotechnological Approaches for Genetic Improvement of Lemon ( (L.) Burm. f.) against Disease.

Among species, lemon is one of the most susceptible to disease, a tracheomycosis caused by the mitosporic fungus which induces chlorosis followed by leaf drop and progressive desiccation of twigs and branches. Severe infection can cause the death of the plant. Since no effective control strategies are available to efficiently control the pathogen spread, host tolerance is the most desirable goal in the struggle against disease.
