Tomato yellow leaf curl (TYLC) is one of the most devastating viral diseases of cultivated
tomato (Lycopersicon esculentum) in tropical and subtropical regions worldwide, and losses …

The majority of plant-infecting viruses utilize an RNA genome, suggesting that plants have
imposed strict constraints on the evolution of DNA viruses. The geminiviruses represent a …

Abstract Cassava (Manihot esculenta Crantz.) is the most important vegetatively propagated
food staple in Africa and a prominent industrial crop in Latin America and Asia. Its vegetative …

Bean golden mosaic virus (BGMV) is transmitted by the whitefly Bemisia tabaci in a
persistent, circulative manner, causing the golden mosaic of common bean (Phaseolus …

Genetic engineering offers a means of incorporating new virus resistance traits into existing
desirable plant cultivars. The initial attempts to create transgenes conferring virus resistance …

Geminiviruses comprise a large and diverse family of viruses that infect a wide range of
important monocotyledonous and dicotyledonous crop species and cause significant yield …

Virus and viroid diseases are serious constraints to the production and profitability of a wide
range of tropical crops. Many plant virus outbreaks have been recorded in the last two …

Genes that confer viral pathogen-derived resistance (PDR) include those for coat proteins,
replicases, movement proteins, defective interfering RNAs and DNAs, and nontranslated …

Cassava mosaic disease is a major constraint for cassava production in Africa, resulting in
significant economic losses. We have engineered transgenic cassava with resistance to …

Cotton, the major cash crop in Pakistan, suffers 30% losses to cotton leaf curl disease,
caused by the geminivirus, cotton leaf curl virus DNA A, plus a satellite component, DNA β …
