Abstract

Elsinoe masingae is a recently described fungal pathogen causing Eucalyptus scab and shoot malformation in South African plantations. Here we present the draft genome sequence of the ex-holotype isolate (CMW 58888 = CMW-IA 1800). Illumina paired-end sequencing generated approximately 24.6 million reads, yielding a 24.8 Mb assembly comprising 176 scaffolds with an N50 of 0.47 Mb and a GC content of 51.04%. BUSCO analysis using the dothideomycetes_odb10 dataset indicated 93.70% completeness, and funannotate predicted 8 883 protein-coding genes. Phylogenetic inference based on ITS, LSU, TEF1 and RPB2 sequences confirmed the identity of the sequenced isolate as E. masingae. The availability of this genome provides an essential resource for developing molecular tools to study the population diversity, epidemiology, and evolutionary history of E. masingae, and enables comparative analyses of pathogenicity and host adaptation among Elsinoe species affecting Eucalyptus and other crops.

南非桉树病病原Elsinoe masingae基因组序列草图

Elsinoe masingae是最近描述的一种真菌病原体，引起南非桉树种植园的结痂和芽畸形。在这里，我们提出了前全型分离物（CMW 58888 = CMW- ia 1800）的基因组序列草图。Illumina配对端测序产生约2460万reads，产生24.8 Mb的组装，包含176个支架，N50为0.47 Mb， GC含量为51.04%。使用dothideomycetes_odb10数据集进行BUSCO分析，完整性为93.70%，funannotate预测了8 883个蛋白质编码基因。基于ITS、LSU、TEF1和RPB2序列的系统发育推断证实该测序分离物为masingae。该基因组的可用性为开发分子工具来研究masingae的种群多样性、流行病学和进化史提供了重要资源，并可以对影响桉树和其他作物的elsinae物种的致病性和宿主适应性进行比较分析。
