Take-all disease, caused by the fungal root pathogen Gaeumannomyces tritici, is considered to be the most important root disease of wheat worldwide. Here we review the advances in take-all research over the last 15 years, focusing on the identification of new sources of genetic resistance in wheat relatives and the role of the microbiome in disease development. We also highlight recent breakthroughs in the molecular interactions between G. tritici and wheat, including genome and transcriptome analyses. These new findings will aid the development of novel control strategies against take-all disease. In light of this growing understanding, the G. tritici-wheat interaction could provide a model study system for root-infecting fungal pathogens of cereals.
小麦全蚀病由禾顶囊壳菌引起，是全球范围内最重要的小麦根部病害。本文综述了过去 15 年中全蚀病研究的进展，重点介绍了在小麦近缘种中发现遗传抗性新来源的情况，以及微生物组在病害发展中的作用。本文还强调了禾顶囊壳菌与小麦之间分子相互作用的最新突破，包括基因组和转录组分析。这些新发现将有助于开发防治小麦全蚀病的新策略。鉴于对这一病害的认识不断加深，禾顶囊壳菌-小麦互作可以为禾本科作物根部真菌病原体提供一个模型研究系统。
