Genetic Diversity of the root-knot nematode Meloidogyne enterolobii in Mulberry Based on the Mitochondrial COI Gene.

ABSTRACT: This study explores the genetic diversity and structure of Meloidogyne enterolobii in mulberry in China. The COI mitochondrial gene (mtCOI) in M.enterolobii populations in Guangdong, Guangxi, and Hunan Provinces was PCR-amplified, sequenced, and analyzed for genetic diversity. The total number of variations, haplotypes (Hap), the average number of nucleotide differences (k), haplotype diversity (H), and nucleotide diversity (π) of mtCOI were 25, 11, 4.248, 0.900, and 0.00596, respectively. Insignificant differences in Fst value (0.0169) and a high level of gene flow (7.02) were detected among the 19-mulberry root-knot nematode populations, and high genetic variation within each population and a small genetic distance among populations were observed. Both phylogenetic analyses
