The symbiotic fungi improve the growth parameters of plants under environmental stresses. To investigate the effect of endophytic fungi under water stress, we investigated the symbiosis of two new isolated endophytic fungi Curvularia spicifera and Gibberella thapsina from Chenopodiaceae species (Kochia stellaris and Chenopodium album) versus mycorrhizal (Funneliformis mosseae) and Serendipita indica fungi with wheat plants under water stress. The experiment was conducted as completely randomized design with three replicates per treatment. The treatments included soil water stress (field capacity (FC) and 50% FC) and fungus (inoculation and non-inoculation). The two new endophytic fungi could colonize wheat root and significantly improved the growth parameters. Curvularia spicifera inoculation resulted to high fresh and dry shoot biomass, proline and protein content and K/Na ratio but this endophyte increased content of electrolyte leakage. Curvularia spicifera-inoculated plants had more activity of the enzyme than S. indica-inoculated plants in ascorbate peroxidase (APX) under water stress while S. indica-inoculated plants showed higher concentration of nutrients. Serendipita indica-inoculated and C. spicifera-inoculants plants did not show significant differences in content of chlorophyll. The contents of proline and proteins as well as the activity of catalase in G. thapsina-inoculated plants were higher than F. mosseae. We found that C. spicifera and G. thapsina improve production of biomass and metabolites in shoot of wheat and they can change water availability in soil. According to compare the functional groups of inoculated fungi, we suggest that the two endophytes could significantly reprogram the growth of wheat plants during stress conditions with unknown mechanisms.

土壤水分状况对不同根系真菌侵染剂对小麦代谢的影响。

共生真菌改善了环境胁迫下植物的生长参数。为了研究内生真菌在水分胁迫下的作用，我们研究了两种新的分离的内生真菌，分别来自藜科（Kochia stellaris和Chenopodium Album）的弯孢菌和赤霉菌与菌根（Sungeriformis mosseae）和Serendipita indica的共生关系。小麦植物在水分胁迫下的真菌。实验按照完全随机设计进行，每个处理重复三遍。处理包括土壤水分胁迫（田间持水量（FC）和50％FC）和真菌（接种和非接种）。这两种新的内生真菌可以在小麦根部定植，并显着改善生长参数。接种弯孢菌后，鲜，干芽生物量，脯氨酸和蛋白质含量以及钾/钠比都很高，但是这种内生菌增加了电解质渗漏的含量。在水分胁迫下，弯曲抗性过氧化物酶（APX）中，与弯孢菌（ Curvularia spicifera）接种的植物的酶活性比S稻（S. indica）的植物高。-接种的植物显示出更高的养分浓度。接种Serendipita indica和接种C. spicifera的植物的叶绿素含量没有显着差异。脯氨酸和蛋白质含量以及过氧化氢酶的活性G. thapsina -inoculated植物比均高于˚F。mosseae。我们发现C. spicifera和G. thapsina改善小麦苗中生物量和代谢产物的生产，它们可以改变土壤中的水分利用状况。通过比较接种真菌的功能组，我们认为这两种内生菌可以在未知条件下显着地重编程小麦在胁迫条件下的生长。
