Interpretive Summary: An unculturable bacterium, ‘Candidatus Liberibacter asiaticus’, causes citrus Huanglongbing (HLB), a highly destructive disease in citrus production worldwide. This research was the first to obtain and release the whole genome sequences of two HLB pathogen strains from Pakistan. The two genome sequences extend the current HLB pathogen database and will contribute to HLB biology research and management.

Technical Abstract: ‘Candidatus Liberibacter asiaticus’ (CLas) is an unculturable, phloem-restricted a-Proteobacteria, associated with citrus Huanglongbing (HLB) which is one of the most destructive diseases in citrus production worldwide. Here, is presented the genome sequences of CLas strains PA19 and PA20 from HLB-affected kinnow trees in Multan, Punjab province, Pakistan. The CLas genomes of PA19 and PA20 comprised of 1,224,156 bp and 1,226,225 bp respectively, with an average GC content of 36.4%. Both harbored the Type 2 prophage. The two CLas genomes from Pakistan, extend the sequence database of CLas and will contribute to CLas biology research and HLB management.
