Complete Genome Sequence Resource for Cercospora apii Causing Leaf Spot of Celery

Abstract

Cercospora apii is an important seedborne pathogenic fungus causing severe Cercospora leaf spot of celery worldwide. Here, we first present a complete genome assembly of C. apii QCYBC from celery, based on Illumina paired-end and PacBio long-read sequencing data. The high-quality genome assembly contains 34 scaffolds with a 34.81 Mb genome size, 330 interspersed repeat genes, 114 noncoding RNAs, and 12,631 protein-coding genes. The benchmarking universal single-copy ortholog (BUSCO) analysis indicated that 98.2% of the BUSCOs were complete, whereas 0.3, 0.7, and 1.1% were duplicated, fragmented, and missing, respectively. Based on annotation, 508 carbohydrate-active enzymes, 243 cytochromes P450 enzymes, 1,639 translocators, 1,358 transmembrane proteins, and 1,146 virulence genes were identified. This genome sequence provides a valuable reference for future studies to improve understanding of the C. apii–celery pathosystem. [Graphic: see text] Copyright © 2023 The Author(s).
