Abstract

'Candidatus Liberibacter asiaticus', an unculturable α-proteobacterium, is associated with citrus huanglongbing (HLB), a devastating disease threatening citrus production in Brazil and worldwide. In this study, a draft whole-genome sequence of 'Ca. L. asiaticus' strain 9PA from a sweet orange (cultivar Pera) tree collected in São Paulo State, Brazil, is reported. The 9PA genome is 1,231,881 bp, including two prophages, with G+C content of 36.7%. This is the first report of a whole-genome sequence of 'Ca. L. asiaticus' from Brazil or South America. The 9PA genome sequence will enrich 'Ca. L. asiaticus' genome resources and facilitate HLB research and control in Brazil and the world.

Keywords: Brazil; citrus greening; fruit; huanglongbing; pathogen diversity; prokaryotes; prophage; tree fruits; whole-genome sequence; ‘Candidatus Liberibacter asiaticus’.
