Abstract

Macrophomina phaseolina is a Catastrophic plant pathogen, which can cause serious reduction in crop production. In the current study, the mitochondrial genome of M. phaseolina is assembled and annotated. The mitogenome of M. phaseolina is a circular molecule of 101,198 bp. The overall nucleotide content is 34.95% A, 35.25% T, 13.30% C, 16.50% G, with a CG content of 29.80%. The mitogenome contains 42 genes, including 14 protein coding genes (PCGs), 2 ribosomal RNA (rRNA) genes and 26 transfer RNA (tRNA) genes. Phylogenetic analyses based on concatenated protein sequences from 15 taxa of five orders in Ascomycota indicated that M. phaseolina is clustered in the order Botryosphaeriales. This study would have a positive impact on the molecular biology research and biological control of Macrophomina fungi in the future.

摘要

Macrophhomina phaseolina是一种灾难性的植物病原体，可导致作物产量严重下降。在目前的研究中，M. phaseolina的线粒体基因组被组装和注释。M. phaseolina 的有丝分裂基因组是一个 101,198 bp 的环状分子。总核苷酸含量为 34.95% A、35.25% T、13.30% C、16.50% G，CG 含量为 29.80%。有丝分裂基因组包含 42 个基因，包括 14 个蛋白质编码基因 (PCG)、2 ​​个核糖体 RNA (rRNA) 基因和 26 个转移 RNA (tRNA) 基因。基于来自子囊菌中五个数量15类群级联的蛋白质序列的系统发育分析表明，M. phaseolina以葡萄球菌目（Botryosphaeriales）的顺序聚集。该研究将对今后巨目真菌的分子生物学研究和生物防治产生积极影响。
