' 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 ' 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 ' L. asiaticus' from Brazil or South America. The 9PA genome sequence will enrich ' L. asiaticus' genome resources and facilitate HLB research and control in Brazil and the world.
‘亚洲韧皮杆菌’（Liberibacter asiaticus）是一种无法培养的α-变形菌，与威胁巴西乃至全球柑橘产业的毁灭性病害——黄龙病有关。本研究报道了一株采自巴西圣保罗州甜橙（品种 Pera）树上的‘亚洲韧皮杆菌’9PA 菌株的全基因组草图。9PA 基因组大小为 1,231,881bp，包含两个前噬菌体，GC 含量为 36.7%。这是巴西或南美洲首次报道的‘亚洲韧皮杆菌’全基因组序列。9PA 基因组序列将丰富‘亚洲韧皮杆菌’的基因组资源，有助于巴西乃至全球黄龙病的研究与防控。
