Xanthomonas citri pv. eucalyptorum strain 4866-2_S43 (formerly X. axonopodis pv. eucalyptorum): the causal agent of bacterial leaf blight on eucalypts recovered in Argentina.

We report the draft genome assembly of strain 4866-2_S43 isolated from a eucalyptus lesion in Argentina and what until recently was caused by pv. (). The genome size is 5 188 607 bp, with a G+C content of 64.

Transgenic Citrange troyer rootstocks overexpressing antimicrobial potato Snakin-1 show reduced citrus canker disease symptoms.

Citrus canker is a major disease caused by Xanthomonas citri pv. citri. Snakin-1 is an antimicrobial peptide, which was previously shown to be effective against different bacterial and fungal diseases in potato, wheat and lettuce when expressed in transgenic plants.

Pacbio sequencing of copper-tolerant Xanthomonas citri reveals presence of a chimeric plasmid structure and provides insights into reassortment and shuffling of transcription activator-like effectors among X. citri strains.

Background: Xanthomonas citri, a causal agent of citrus canker, has been a well-studied model system due to recent availability of whole genome sequences of multiple strains from different geographical regions. Major limitations in our understanding of the evolution of pathogenicity factors in X. citri strains sequenced by short-read sequencing methods have been tracking plasmid reshuffling among strains due to inability to accurately assign reads to plasmids, and analyzing repeat regions among strains.

Management of Citrus Canker in Argentina, a Success Story.

Citrus canker is an important bacterial disease of citrus in several regions of the world. Strains of type-A (Xc-A) group are the primary pathogen where citrus canker occurs. After Xc-A entered the Northeast of Argentina in 1974, the disease spread rapidly from 1977 to 1980 and then slowed down and remained moving at slow pace until 1990 when it became endemic.

Complete Genome Sequences of Six Copper-Resistant pv. citri Strains Causing Asiatic Citrus Canker, Obtained Using Long-Read Technology.

The gammaproteobacterium pv citri causes Asiatic citrus canker. Pathotype A strains have a broad host range, which includes most commercial citrus species, and they cause important economic losses worldwide. Control often relies on frequent copper sprays.
