Interpretive Summary: Citrus Huanglongbing (HLB, also called citrus greening disease) is a devastating disease in citrus cultivation around the world. The disease is caused by a non-culturable bacterial pathogen. Research in HLB has been highly challenging. This study acquired and published the whole genome sequence of an HLB pathogen strain collected from Chaozhou City of Guangdong Province, China, where HLB was first described over a hundred years ago. This genome sequence enriches the HLB pathogen genome database with a unique geographical reference and will benefit research in HLB epidemiology and evolution of the pathogen.

Technical Abstract: "Candidatus Liberibacter asiaticus" is a fastidious phloem-limited Gram-negative proteobacterium causing citrus Huanglongbing (HLB, yellow shoot disease). HLB has devastated citrus production around the world. Due to the nutritional fastidiousness, current knowledge about "Ca. L. asiaticus" is mostly derived from genomic analyses. This study acquired the whole genome sequence of "Ca. L. asiaticus" strain GDCZ collected from Chaozhou City of Guangdong Province, China, where HLB was first described over a hundred years ago. The GDCZ genome is 1,230,507 bp with G+C content of 36.4% and a Type 2 prophage. The genome sequence enriches "Ca. L. asiaticus" genome database with a unique geographical reference and will benefit research in HLB epidemiology and evolution of the pathogen.
