Arbuscular mycorrhizal fungi alleviate salt stress in lupine (<italic>Lupinus termis</italic> Forsik) through modulation of antioxidant defense systems and physiological traits

The present study was carried with the aim to demonstrate and examine the impact of arbuscular mycorrhizal fungi (AMF) on the growth, anti-oxidants metabolism and some key physio-biochemical attributes including the osmotic constituents in <italic>Lupinus termis</italic> exposed to salt stress. Salt stress (250 mM NaCl) reduced growth, AMF colonisation, relative water content and chlorophyll pigment content. However, AMF ameliorated the negative effect of salinity on these growth parameters. Salt stress increased the activities of key antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and peroxidase (POD). Inoculation of AMF enhanced the activities of these enzymes and caused an increase in the accumulation of osmotic components resulting in the maintainence of tissue water content. Proline, glycine betaine and sugars increased with salinity stress and AMF inoculation. Plants subjected to salt stress showed considerable variations in the endogenous levels of growth hormones. Reduced lipid peroxidation and increased membrane stability in AMF inoculated plants and enhanced activity of anti-oxidants enzymes confers the role of AMF in assuaging the salt stress induced deleterious effects.

The aim of present study was to examine the effect of arbuscular mycorrhizal fungi (AMF) on the growth, lipid peroxidation, antioxidant enzyme activity and some key physio-biochemical attributes in cowpea (<italic>Vigna unguiculata</italic> [L.] Walp.) subjected to salt stress. Salt stress (200 mM NaCl) reduced growth, biomass, relative water content and chlorophyll pigment content in cowpea leaves. AMF ameliorated the negative impact of salinity on the growth parameters studied. The activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), peroxidase (POD) and glutathione reductase (GR) enhanced under salt stress and AMF inoculation further enhanced their activity, thus strengthening the plant’s defense system. Proline content increased in salt stressed plants as well as AMF-inoculated plants providing efficient protection against salt stress. Besides this AMF also increased uptake of mineral elements which have direct impact on the osmoregulation of the plants. The present study shows that AMF possesses the potential to enhance salt tolerance of cowpea.

Root Collar

Data on tomato fitness improvement by arbuscular mycorrhizal fungi (AMF) remain patchy. The present study was initiated to evaluate the effect of the period of AMF inoculation as well as the level of mineral manure on tomato growth. The experiment took place from June to October 2016, in the West African Science Service Center on Climate Change and Adapted Land Use greenhouse. AMF inocula were applied to seeds and/or transplants, each receiving three different levels of chemical fertilizer. The impact of the inoculation period and the level of fertilization, were assessed on plant growth parameters, including height, number of functional leaves, root-collar diameter, and root length. Observation of hyphae, arbuscules and vesicles was carried out by roots staining method and anabled the determination of mycorrhization parameters. Plants Mycorrhizal dependence was assessed with their fresh and dry mass. An analysis of variance and post ANOVA analysis was performed using the Newman-Keuls test (P= .05) for the comparison of means. The findings pointed that, when transplanting, the difference between mycorrhized plants and non-mycorrhized ones was very highly significant in terms of the height of the stem (P= .00), the length of the taproot, and the root collar diameter. The lower the level of manure was, the higher the frequency of infection has been (73.33% for MS1 and MSR1; 76.67% for MR1).Transplants growing without a supply of mineral manure expressed greater mycorrhizal dependence (66% for MSR1). Arbuscular mycorrhization of the tomato is profitable for its optimal development. The endomycorrhization of tomato can be done during sowing or transplanting with the same benefits but, with a low level of fertilizer. So, it’s necessary to controll the intake of mineral manure because it influences the natural mycorrhization of plants.

The Impact

Eclipta prostrata (L.) is an important and well-known medicinal plant due to its valuable bioactive compounds. Microorganisms, including arbuscular mycorrhizal fungi (AMF), and salinity could directly impact plant metabolome, thus influencing their secondary metabolites and the efficacy of herbal medicine. In this study, the role of different single AMF species (Funneliformis mosseae, Septoglomus deserticola, Acaulospora lacunosa) and a mixture of six AMF species in plant growth and physio-biochemical characteristics of E. prostrata under non-saline conditions was investigated. Next, the most suitable AM treatment was chosen to examine the impact of AMF on physio-biochemical features and polyphenol profiles of E. prostrata under saline conditions (100 and 200 mM NaCl). The findings indicated that AMF mixture application resulted in more effective promotion on the aboveground part of non-saline plants than single AMF species. AM mixture application improved growth and salt tolerance of E. prostrata through increasing the activity of catalase, peroxidase (at 4 weeks), proline, and total phenolic content (at 8 weeks). Such benefits were not observed under high salinity, except for a higher total phenolic concentration in mycorrhizal plants at 8 weeks. Through high-performance liquid chromatography, 14 individual phenolic compounds were analyzed, with wedelolactone and/or 4,5-dicaffeoylquinic acid abundant in all treatments. Salinity and mycorrhizal inoculation sharply altered the polyphenol profiles of E. prostrata. Moderate salinity boosted phenolic compound production in non-AM plants at 4 weeks, while at 8 weeks, the decline in the content of phenolic compounds occurred in uncolonized plants subjected to both saline conditions. Mycorrhization augmented polyphenol concentration and yield under non-saline and saline conditions, depending on the growth stages and salt stress severity. Plant age influenced polyphenol profiles with usually a higher content of phenolic compounds in older plants and changed the production of individual polyphenols of both non-AM and AM plants under non-stress and salt stress conditions. A better understanding of factors (involving mycorrhiza and salinity) affecting the phenolic compounds of E. prostrata facilitates the optimization of individual polyphenol production in this medicinal plant.

The Impact

The impact of indigenous arbuscular mycorrhizal fungi (AMF) on agronomic characteristics of sunflower (Helianthus annuus L.) was evaluated in a pot experiment. The indigenous AMF, including Glomus intraradices, Glomus mosseae, and Glomus viscosum, were isolated from an agricultural field in which cotton and sunflower plants were grown. The most abundant species (G. viscosum) was multiplied in a monospecific culture. Sunflower plants were inoculated with the mixture of three selected AMF species or solely with G. viscosum. The number of leaves, shoot length, head diameter, above ground biomass, and seeds mass were significantly higher in the plant inoculated with AMF mixture followed by individual inoculation with G. viscosum followed by the control. AMF mixture outperformed the G. viscosumby increasing mycorrhizal dependency and mycorrhizal inoculation effect of sunflower. The results indicate that AMF mixture could be considered as a good inoculum for improving growth and yield of sunflower in sustainable agriculture.
