Huanglongbing (HLB) is associated with Candidatus Liberibacter asiaticus (CLas). It is a destructive disease of citrus. The objective of this study was to determine the genetic diversity of 90 strains of CLas infecting eight citrus species trees from the Central Pacific in Mexico. Genetic diversity among CLas was estimated by fourteen variable numbers of tandem repeat (VNTRs) loci. Three loci were polymorphic, SSR00 and SSR077 amplified four alleles each, while the locus SSR-A amplified two alleles, and the other loci only one allele per locus, resulting in a total of 21 alleles. Dendrogram analysis showed two clusters. No clear genetic structure was found in relation to geographical origin or host. The cluster I was mostly constituted by the majority of CLas strains (82%), but the cluster II comprised twelve strains of CLas collected in Tecoman location, State of Colima, and were obtained from different citrus hosts species. The frequency of 17 haplotypes among strains of CLas from the states of Nayarit, Jalisco, Colima and Michoacán was analyzed; in Colima 14 haplotypes were determinated, while in Michoacan all strains were identified in one haplotype. These results indicate a large genetic diversity among the strains of CLas present in the Central Pacific region in Mexico.
