Complete Genome Sequence of Xanthomonas arboricola pv. juglandis Strain DW3F3, Isolated from a Juglans regia L. Bacterial Blighted Fruitlet

Abstract

Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis DW3F3, a strong pathogenic strain isolated from blighted walnut immature fruit (Juglans regia L. cv. Qingxiang). The genome consists of a single chromosome (5,144 kb).

Comparative Genomics of Xanthomonas euroxanthea and Xanthomonas arboricola pv. juglandis Strains Isolated from a Single Walnut Host Tree

“…The genome size of CPBF 427 (5.23 Mbp) is roughly equal to the genome size reported for other sequenced X. arboricola pv. juglandis genomes, namely Xaj 417 [ 62 ], NCPPB 1447 [ 9 ], J303 [ 63 ], DW3F3, [ 64 ], and CFBP 2528 T and CFBP 7179 [ 24 ] or CFSAN033077 and CFSAN033080 [ 65 ]. The genomes of X. euroxanthea strains CPBF 367, CPBF 424 T , and CPBF 426 were smaller (ranging from ≈ 4.90 to 4.97 Mbp), presenting values closer to the nonpathogenic or avirulent strains of X. arboricola , i.e., with uncertain pathogenicity or belonging to non- juglandis , non- pruni , and non- corylina pathovars, with genome sizes inferior to 5 Mb [ 66 , 67 , 68 ].…”

Selection and validation of reference genes for gene expression studies in Xanthomonas arboricola pv. juglandis subjected to abiotic stress

“…Definition of plant–pathogen relationships using multi‐omics approaches, including genomics, transcriptomics, proteomics, and metabolomics, allows us to obtain multilayered information to elucidate the complex mechanisms within the plant cellular system (Meena et al, 2017). Furthermore, analysis of the whole genome sequence of Xaj strain DW3F3 allows elucidation of the mechanisms involved in plant–bacteria interactions (Fu et al, 2018).…”

Xanthomonas arboricola pv. juglandis and pv. corylina: Brothers or distant relatives? Genetic clues, epidemiology, and insights for disease management

“…Due to the possibility of infection of all the above-ground organs of the tree, WBB, BAN, and VOC have a great economic impact (Fu et al, 2018). The diseases may decrease the effectiveness of nursery production and reduce crop quality and yield due to premature fruit Epidemiology and control: For both pathogens infected nursery material is the main pathway for their introduction and spread into newly cultivated areas; additionally, infected nursery material is the source of primary inoculum.…”

“…Due to the possibility of infection of all the above‐ground organs of the tree, WBB, BAN, and VOC have a great economic impact (Fu et al, 2018 ). The diseases may decrease the effectiveness of nursery production and reduce crop quality and yield due to premature fruit drop, as well as causing shell staining and kernel browning of the nuts still hanging on the tree (Belisario et al, 2001 , 2002 ; Bouvet, 2005 ; Hajri et al, 2010 ; Lang & Evans, 2010 ; Lindow et al, 2014 ; Özaktan et al, 2009 ; Rudolph, 1933 ).…”
