Abstract

Apple replant disease (ARD) caused by the fungal pathogen f. sp. () MR5 brings annual losses to apple production within China. However, the genomic information of the pathogen is not yet available. Here, we obtained the whole-genome sequence of the highly virulent MR5 using the Illumina PE150 platform. The genome size was 42.76 Mb and consisted of 9,047 genes. The GC content was 48.80%, and several genes potentially associated with pathogenicity were identified, such as carbohydrate-active enzymes, secreted proteins, and secondary metabolite gene clusters. There were 260 specific virulence factor genes, mainly related to fungal vegetative growth and the production of cell wall-degrading enzymes. These data will aid future studies investigating host-pathogen interactions and help us develop suitable disease management strategies.

摘要

由真菌病原体 f. sp. () MR5 引起的苹果再植病（ARD）给中国国内的苹果生产带来了年度损失。然而，该病原体的基因组信息尚未可得。在此，我们使用Illumina PE150平台获得了高毒力MR5的全基因组序列。基因组大小为42.76 Mb，由9047个基因组成。GC含量为48.80%，并鉴定出了几个可能与致病性相关的基因，如碳水化合物活性酶、分泌蛋白和次生代谢物基因簇。有260个特定的毒力因子基因，主要与真菌营养生长和细胞壁降解酶的产生有关。这些数据将有助于未来研究宿主-病原体相互作用，并帮助我们制定合适的病害管理策略。
