摘要:
深色有隔内生真菌(Dark septate endophytes,DSE)是一类定殖于植物根内的小型真菌,广泛存在各种生境中,其在胁迫生境中的生态分布、生态功能与作用机理是近年来的研究热点。本文从DSE的生态分布、胁迫生境DSE的生态功能和DSE真菌增强植物抗逆性的作用机理等方面进行综述。调查研究发现,从平原低地到热带、温带、冻原及南北极地区,野生植物根部普遍定殖着DSE真菌,尤其在干旱、高温、寒冷、盐害、重金属污染和养分贫瘠等胁迫生境中,DSE真菌的分布更为普遍。环境胁迫条件下,植物根部共生DSE真菌能够改善植物矿质营养和光合生理、调节植物内源激素平衡、增强植物抗氧化生理,从而促进宿主植物生长、增强植物抗逆能力,以及改变植物对重金属的吸收累积,在植物耐受和适应胁迫环境中起着重要的调节作用。但这些研究主要从生态现象进行了研究,目前对DSE增强宿主植物抗逆性的作用机理仍很缺乏、不够系统深入。未来应建立DSE真菌种质资源库,加强DSE真菌的应用技术研究;结合现代生物技术和方法,系统深入研究DSE真菌提高植物抗逆性的生理和分子机制,旨在为利用DSE真菌增强植物适应环境胁迫提供理论依据。(表1参92)
Abstract:
Dark Septate Endophytes (DSE) are a group of small fungi that colonize plant roots and widely exist in various habitats. Their ecological distribution, ecological function and mechanism of action in stress habitats have been a research hotspot in recent years. In this paper, the ecological distribution of DSE, the ecological function of DSE in stressed habitats and the mechanism of DSE enhancing plant stress resistance were reviewed. According to the investigation, DSE are commonly colonized in the roots of wild plants from lowland plains to tropical, temperate, tundra and arctic and Antarctic regions, especially in stress habitats such as drought, high temperature, cold, salt damage, heavy metal pollution and barren nutrients, and the distribution of DSE fungi is more common. Under conditions of environmental stress, DSE symbiosed with plant root can improve plant mineral nutrition and photosynthetic physiological, adjusting plant endogenous hormone balance and enhance antioxidant physiological of plants, so as to promote the growth of host plants, enhance stress resistance of plants, and change absorption and accumulation of heavy metals in plants. And DSE plays an important regulating role in tolerance and adapting to the stress environment of plants. However, these studies are mainly based on ecological phenomena. At present, the mechanism of DSE enhancing host plant stress resistance is still lacking and not thorough enough. In the future, the germplasm bank of DSE should be established and the applied technology research of DSE should be strengthened. Combined with modern biotechnology and methods, the physiological and molecular mechanisms of DSE improving plant stress resistance should be systematically studied in order to provide theoretical basis for enhancing plant adaptation to environmental stress by using DSE.
