Abstract

Plant roots are inhabited by an enormous variety of microorganisms, including fungi, which can control the growth as well as regulate the health of the host plants. The mycobiome composition of the roots of wheat plants, especially spelt, under drought stress has been rarely investigated. Therefore, the aim of the present study was to examine the composition of fungal communities in the root endosphere and rhizosphere of three Triticum aestivum ssp. spelta L. cultivars and one Triticum aestivum ssp. vulgare L. cultivar, grown under drought and controlled conditions in different soil preparations. Culture-dependent fungal community profiling was performed to examine the impact of rhizocompartments (endosphere, rhizosphere), host genotype, watering status and different soil preparation on roots mycobiome structure. A total of 117 fungal strains, belonging to 22 genera, were found to colonize the internal and external parts of roots in T. aestivum ssp. spelta L. and T. aestivum ssp. vulgare L. cultivars. The results showed that the part of root and soil preparation type significantly determined the mycobiome composition of wheat roots.

摘要

植物根系中栖息着大量的微生物，包括真菌，它们可以控制植物的生长和调节其健康。在干旱胁迫下，小麦，尤其是斯佩尔特小麦根系中的真菌生物群落组成还很少被研究。因此，本研究的目的是研究在不同土壤准备条件下，干旱和对照条件下生长的三种普通小麦（Triticum aestivum ssp. spelta L.）和一种普通小麦（Triticum aestivum ssp. vulgare L.）品种的根系内生和根际真菌群落组成。采用培养依赖的真菌群落分析方法，研究了根际区（内生、根际）、宿主基因型、浇水状况和不同土壤准备对根际真菌生物群落结构的影响。在普通小麦（Triticum aestivum ssp. spelta L.）和普通小麦（Triticum aestivum ssp. vulgare L.）品种的根系内部和外部共发现了 117 株真菌菌株，属于 22 个属。结果表明，根的部分和土壤准备类型显著决定了小麦根系的真菌生物群落组成。
