Evolution and spread of <i>Xanthomonas citri</i> subsp. <i>citri</i> in the Sao Paulo, Brazil, citrus belt inferred from 758 novel genomes.

ABSTRACT: The São Paulo state citrus belt in Brazil is a major citrus production region. Since at least 1957, citrus plantations in this region have been affected by citrus canker, an economically damaging disease caused by Xanthomonas citri subsp. citri (Xcc). For about 50 years, until 2017, a citrus canker eradication programme was carried out in this region. In this work, our aim was to investigate the effects of the eradication programme on genetic variability and evolution of Xcc. To this end, we sequenced and analysed 758 Xcc genomes sampled in the São Paulo citrus belt, together with 730 publicly available Xcc genomes from around the world. Our phylogenomic analyses show that these genomes can be grouped into seven major lineages and that in São Paulo
