Genome sequence of Fusarium oxysporum strain ByF01, the causal agent of root rot of Knoxia roxburghii in China.

ABSTRACT

OBJECTIVES: Knoxia roxburghii is a member of the madder (Rubiaceae) family. This plant is cultivated in different areas of China and recognized for its medicinal properties, which leads to its use in traditional Chinese medicine. The incidence of root rot was 10-15%. In June 2023, the causal agent of root rot on K. roxburghii was identified as Fusarium oxysporum. To the best of our knowledge, this is the first report of the complete genome of F. oxysporum strain ByF01 that is the causal agent of root rot of K. roxburghii in China. The results will provide effective resources for pathogenesis on K. roxburghii and the prevention and control of root rot on this host in the future. DATA DESCRIPTION To understand the molecular mechanisms used by F. oxysporum to cause root rot on K. roxburghii, strain ByF01 was isolated from diseased roots and identified by morphological and molecular methods. The complete genome of strain ByF01 was then sequenced using a combination of the PacBio Sequel IIe and Illumina sequencing platforms. We obtained 54,431,725 bp of nucleotides, 47.46% GC content, and 16,705 coding sequences.
