Not AvailableSugarcane yellow leaf virus (SCYLV) is one of the most widespread virus diseases affecting sugarcane worldwide. The virus has been responsible for drastic economic losses in most sugarcane growing regions and remains a major concern for sugarcane breeders. Symptoms are characterized by intense yellowing of the midrib, which extends to the leaf blade followed by tissue necrosis from the leaf tip towards the leaf base. Such symptomatic leaves are usually characterized by increased respiration, reduced photosynthesis, a change in the ratio of hexose to sucrose, and an increase in starch. Viral infection often affects carbon assimilation and metabolism in host plants. Sugarcane growth is always stunted in severe infections. SCYLV is mainly propagated by planting cuttings from infected stalks. Phylogenetic analyses have confirmed the worldwide distribution of at least eight SCYLV genotypes (BRA, CHN1, CHN3, CUB, HAW, IND, PER, and REU). Evidence of the recombination has been found in the SCYLV genome which contains potential recombination signals in the ORF1/2 and ORF5. This shows that recombination plays an important role in the selection pressure on SCYLVNot Availabl
