Interpretive Summary: Citrus Huanglongbing (HLB, yellow shoot disease, also known as citrus greening disease) is currently threatening citrus production in California. The first case of HLB in California was reported from Hacienda Heights in 2012. In 2015, HLB-infected citrus trees were found in the City of San Gabriel, adjacent to Hacienda Heights. A question remains if the two HLB cases were related. The genome sequence of the bacterium associated with HLB, named as “Candidatus Liberibacter asiaticus”, from Hacienda Heights was previously reported. This study sequenced the whole genome of the HLB bacterium from San Gabriel. The information will have immediate impact on understanding HLB epidemiology in California and development of HLB control strategies.

Technical Abstract: The draft genome sequence of “Candidatus Liberibacter asiaticus” strain SGCA5 from an orange citrus tree in San Gabriel, California, is reported. The SGCA5 strain has the genome size of 1,201,445 bp, G+C content of 36.4 %, 1,152 predicted open reading frames (ORFs), and 42 RNA genes.
