Molecular diversity of Radopholus similis (Cobb 1913) Thorne (1949) (Nematoda: Pratylenchidae) affecting banana from Costa Rica
European Journal of Plant Pathology 164 (3), 439-446
Abstract: Radopholus similis is one of the most important diseases in banana in tropical/subtropical regions worldwide. The knowledge of its molecular diversity in specific areas could help to understand its distribution, ways of expansion, control methods, differential pathogenicity, and sustainable plant breeding programs. This study explores the molecular diversity of R. similis in an extensive survey in banana plantations in Costa Rica using two molecular markers, one genomic (ITS region) and another mitochondrial (COI). The results showed a low molecular variability, being dominated by a prevalent haplotype in both markers. Three haplotypes have been detected for each molecular marker respectively. The haplotypes present in Costa Rica are similar to others found in other areas of Central America (Colombia, Panama) and these haplotypes are also distributed worldwide. These results suggested a unique or limited number of introductions of this pathogen in Central America and a possible expansion within the continent by infected plant material.
