Genome sequence resource of Xanthomonas citri pv. citri from formalin-fixed citrus leaf specimens showing canker lesions collected in 1982.

Xanthomonas citri pv. citri (Xcc) is the causative agent of citrus canker, one of the most devastating disease threatening global citrus production. Here, we present the genome sequence of Xcc strain GD82 from a formalin-fixed citrus leaf specimen showing canker lesions collected at 1982 in Guangdong Province, China. The GD82 genome comprised of 5,197,217 bp with G+C content of 64.8 %, along with four circular plasmids, pXAC33 (32,377 bp), pXAC64 (63,972 bp), pXAC47 (47,810 bp) and pGD82.1 (219,560 bp). This is the oldest Xcc genome from historical citrus canker specimens in China, which will enrich the current Xcc genome database and facilitate genomic evolution research of Xcc.
