The Genome Sequence of Citrus Melanose Pathogen Diaporthe citri and Two Citrus related Diaporthe species

The melanose diseases is one the most widespread and economically important fungal diseases of citrus worldwide. The causative agent is filamentous fungus Diaporthe citri Wolf (syn. Phomopsis citri H.S. Fawc.). Here, we report genome assemblies of three strains of D. citri, namely strains ZJUD2, ZJUD14 and Q7, generated using a combination of PacBio Sequel long-read and Illumina paired-end sequencing data. The assembled genomes of D. citri ranged 53.97 Mb to 63.64 Mb in genome size, containing 15,977 ~ 16,622 protein-coding genes. We also sequenced and annotated the genome sequences of two Citrus related Diaporthe species, including D. citriasiana and D. citrichinensis. In addition, the citrus-related Diaporthe genomes database was established to provide a public platform to access the genome sequence, genome annotation and comparative genomics data of these Diaporthe species. The described genome sequences and the citrus-related Diaporthe genomes database can provide a useful resource in the study of fungal biology, pathogen-host interaction, molecular diagnostic marker development, and population genomic analyses of Diaporthe species. When new genomes of Diaporthe species are sequenced, the database will be updated regularly. The citrus-related Diaporthe genomes database is freely available for non-profit use at http://www.zjudata.com/blast/diaporthe.php.
