Improved Whole-Genome Sequence of Fusarium meridionale, the Fungal Pathogen Causing Fusarium Head Blight in Rice

Abstract

Members of the Fusarium graminearum species complex (FGSC) cause extensive yield losses in cereal production worldwide, and food safety concerns due to the accumulation of Fusarium toxins in infected grains. Among these pathogens, F. meridionale is responsible for Fusarium head blight of wheat and rice, ear and stalk rot of maize, and pod blight of soybean. Here, we present an improved genome assembly of F. meridionale strain SR5 isolated from rice in China based on PacBio long-read sequencing and Illumina short-read sequencing technology. The assembled genome of SR5 has a total size of 36.82 Mb, an N50 scaffold length of 7.82 Mb, nine scaffolds, and encodes 12,409 predicted genes. These high-quality data expand FGSC genomic resources and provide a valuable resource for better understanding their genetic diversity and the molecular basis of pathogenesis, which will facilitate the development of an effective control strategy.[Graphic: see text] Copyright © 2021 The Author(s).
