Introduction

Endophytic fungi associated with desert plants have a crucial role to enable these plants to tolerate abiotic stress, such as heat and drought.

Methods

In this study, a thermophilic fungal endophyte was isolated from a hot desert-adapted plant, Cullen plicata Delile. The endophytic fungus was (molecularly) identified as Thermomyces lanuginosus, and inoculated plants were coded as E+ and the control as E-.

Results

This fungus had an effective growth-promoting activity on its host plant and increased the plant resistance to heat stress as well.

Discussion

Our findings demonstrate that thermophilic fungal endophytes can enhance drought and heat stress tolerance in desert plants by ecophysiological mechanisms and improve growth of its host plants.

内生真菌 Thermomyces lanuginosus 对减轻其寄主沙漠植物 Cullen plicata 的热应激的作用

介绍

与沙漠植物相关的内生真菌在使这些植物能够耐受非生物胁迫（如高温和干旱）方面发挥着至关重要的作用。

方法

在这项研究中，从适应炎热沙漠的植物Cullen plicata Delile 中分离出一种嗜热真菌内生菌。内生真菌被（分子）鉴定为疏毛嗜热丝孢菌，接种的植物被编码为E+，对照被编码为E-。

结果

这种真菌对其寄主植物具有有效的促生长活性，并增加了植物对热胁迫的抵抗力。

讨论

我们的研究结果表明，嗜热真菌内生菌可以通过生态生理机制增强荒漠植物的干旱和热胁迫耐受性，并促进其寄主植物的生长。
