The complete genome sequence of "Candidatus Liberibacter asiaticus" strain 9PA and the characterization of field strains in the Brazilian citriculture.

ABSTRACT: "Candidatus Liberibacter asiaticus" (CLas) is associated with citrus huanglongbing, a severe disease with global importance that affects citrus production in Brazil. This study reports the first complete genome of a Brazilian strain of CLas. The genomic structure comparison of strain 9PA with those of 13 complete CLas genomes revealed 9,091 mismatches and 992 gaps/insertions, highlighting eight locally colinear blocks, among which six are in the prophage region. Phylogenetic analysis categorized 13 CLas genomes into two clusters with 9PA clustered with strains from China and the United States. Whole-genomic comparison identified diverse hypervariable genomic regions (HGRs). Three HGRs in the chromosomal region and three in the prophage region were selected and investigated by polyme
