ABSTRACT The bacterium Xanthomonas citri pv. anacardii is the agent of angular
leaf spot of the cashew tree (Anacardium occidentale L.). The complete genome se-
quencing of the strain IBSBF2579 was done on an Illumina HiSeq 2500 platform. The
de novo assembly of the X. citri pv. anacardii strain IBSBF2579 genome yielded 133
contigs, with a size of 5,329,247 bp and a G+C content of 64.03%. The prediction
was performed by GeneMarkS and the automatic annotation by Rapid Annotations
using Subsystems Technology (RAST), with 4,406 identified genes.
T
he cashew tree is native to Brazil (1) and grows in South America’s tropical regions,
mainly in the northeast of the country (2). Cashew nut production may be impaired
by the occurrence of diseases, such as standout angular leaf spot caused by Xanthomo-
nas citri pv. anacardii and X. citri pv. mangiferaeindicae (3, 4). These bacteria show
pathological differences in cashew and mango trees, being able to multiply and survive
in different hosts in the Anacardiaceae family (5, 6). However, until now, only X. citri pv.
mangiferaeindicae (LMG 941) has been sequenced (7). Here, we report the whole-
genome sequence of the type strain of X. citri pv. anacardii (IBSBF2579 = ICMP4088),
which is nonpigmented and was isolated from a cashew tree in Brazil. The genome
sequencing was performed by using the Illumina HiSeq 2500 platform at the Functional
Genomics Center of the University of São Paulo. The libraries were prepared with the
Illumina Nextera XT DNA library prep kit v 4, and sequencing was performed on a HiSeq
flow cell v4, with the HiSeq SBS kit v4 and paired reads of 100 bp (2). Initially, the
quality reads were analyzed by FastQC (8), and read trimming to remove the adapters
was performed by using FASTX-Toolkit (v. 0.0.13) (9). The genome de novo assembly
was carried out using SPAdes (v. 1.10) (10), yielding 133 contigs of 500 bp (N
50
,
150,594 bp), with the largest contig being 344,686 bp, for a total assembly size of
5,329,247 bp with a G+C content of 64.03%. The annotation using GeneMarkS (11)
predicted 4,406 genes by Rapid Annotations using Subsystems Technology (RAST) (12).
All assembly statistics were generated with QUAST (v.4.6) (13).
