The response of arbuscular mycorrhizal fungi (AMF)-inoculated plants to environmental stresses including drought stress is a complex phenomenon that involves activation or modification of processes occurring at physiological, biochemical, and molecular levels. However, the information on the ionomic and biochemical responses of AMF-inoculated plants under drought stress is limited. This study aimed to investigate the effect of AM fungus Funneliformis mosseae on maize plant growth, uptake of nutrients, and antioxidant responses of the plant to water-deficit stress under greenhouse conditions in a sterilized calcareous soil(Typic Calcixerepts). The experiment was laid out in a two-factor experiment in a completely randomized design with four replicates. The experimental factors included three different water regimes (100%, 70%, and 50% field capacity (FC)) and AM fungus at two levels (inoculated with or without F. mosseae). Water-deficit stress reduced plant biomass, chlorophyll index, nutrients uptake (P, K, Ca, Mg, Fe, Zn, Mn and Cu in shoots and roots), root colonization but increased malondialdehyde content. Inoculation with F. mosseae had a positive effect on plant growth, chlorophyll index, and nutrients uptake. Activities of guaiacol peroxidase (12.4%), superoxide dismutase (6.5%), and catalase (21.6%) as well as total phenolic content (62.5%) were higher in mycorrhizal plants as compared to non-mycorrhizal plants at 50% FC level. Lipid peroxidation (36.6% and 39.4% at 70 and 50% FC levels, respectively) was higher in non-AM plants as compared to AM plants. Under non-stress conditions, growth and nutrients uptake of mycorrhizal plants were greater than non-mycorrhizal ones. In general, the results of this study indicated that inoculation with F. mosseae through the improvement of ionomic and biochemical status of the plant can mitigate the detrimental effects of water-deficit stress on maize plants. The results of this study also suggest that the shoot and root ionome could be a useful phenotype for understanding the complicated interaction between F. mosseae and maize plant by providing readouts indicative of the biochemical processes occurring in the roots and shoots.

接种丛枝菌根真菌（AMF）的植物对包括干旱胁迫在内的环境胁迫的响应是一个复杂的现象，涉及激活或修饰在生理，生化和分子水平上发生的过程。但是，有关在干旱胁迫下接种AMF的植物在生理和生化反应方面的信息有限。这项研究旨在调查AM真菌Funneliformis mosseae的影响在无菌钙质土壤（典型钙化肽）上温室条件下玉米植物的生长，养分的吸收以及植物对缺水胁迫的抗氧化反应 该实验以两因素实验的形式进行，采用完全随机的设计，一式四份。实验因素包括三种不同的水情（100％，70％和50％的田间持水量（FC））和两种水平的AM真菌（接种或不接种F. mosseae）。缺水胁迫减少了植物的生物量，叶绿素指数，养分吸收（茎和根中的P，K，Ca，Mg，Fe，Zn，Mn和Cu），根部定植但增加了丙二醛含量。接种F. mosseae对植物生长，叶绿素指数和养分吸收有积极影响。菌根植物的愈创木酚过氧化物酶（12.4％），超氧化物歧化酶（6.5％）和过氧化氢酶（21.6％）的活性以及总酚含量（62.5％）在FC含量为50％的情况下要高于非菌根植物。与AM植物相比，非AM植物的脂质过氧化作用（在70％和50％FC水平下分别为36.6％和39.4％）更高。在非胁迫条件下，菌根植物的生长和养分吸收均高于非菌根植物。总的来说，这项研究的结果表明接种F. mosseae通过改善植物的生物学和生化状况，可以减轻水分亏缺胁迫对玉米植物的有害影响。这项研究的结果还表明，通过提供指示根和芽中发生生化过程的读数，芽和根离子组可能是有用的表型，用于了解苔藓和玉米植物之间复杂的相互作用。
