The purpose of the present research was to study the diversity of bacterial endophytes inhabiting the halophytic plant black saxaul (Haloxylon aphyllum Minkw.). A total of 20 bacterial isolates were isolated from tissues of black saxaul and identified based on their 16S rRNA genes analysis and comparison with the closest relatives registered in GenBank nucleotide data bank from the National Centre for Biotechnology Information. The endophytes were checked for plant growth-promoting activity toward cucumber plants and the strains Bacillus amyloliquefaciens HAPH2, Priestia endophytica HAPH5, Bacillus subtilis HAPH7, Bacillus toyonensis HAPH8, Halomonas sulfidaeris HAPH11, Isoptericola halotolerans HAPH12, Planomicrobium soli HAPH15, and Pseudomonas kilonensis HAPH16 demonstrated high plant growth-promoting activity of cucumber in four soil salinity levels (0, 25, 50, and 100 mM) after seeds' inoculation. These bacterial endophytes were able to fix nitrogen, solubilize phosphates, and produce indole-3-acetic acid, 1-aminocyclopropane-1-carboxylate deaminase, and siderophores which are considered as the main plant growth-promoting traits. After field experiments, the best plant growth-promoters can be used as bioinoculants for plants' growth improvement in salinity conditions.

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 (Vigna unguiculata [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.

“…An alternative N resource to mitigate such drawbacks is biological nitrogen fixation by legumes, which plays a major role in sustaining or improving soil productivity (Santi et al, 2013; Egamberdieva et al, 2018). Legumes are grown in many countries of the world and are considered an important food source for human and animal nutrition (Lüscher et al, 2014; Egamberdieva et al, 2015). However, abiotic stresses such as drought and salinity threaten the growth and yield of legumes and other crops (Bodner et al, 2015; Egamberdieva et al, 2016a, 2017b; Abd Allah et al, 2017).…”

Chickpea (Cicer arietinum L.) is an important legume originating in the Mediterranean and the Middle East and is now cultivated in several varieties throughout the world due to its high protein and fiber content as well as its potential health benefits. However, production is drastically affected by prevalent water stress in most soybean-growing regions. This study investigates the potential of biochar to affect chickpea-Rhizobium symbiotic performance and soil biological activity in a pot experiment. Two different biochar types were produced from maize using different pyrolysis techniques, i.e., by heating at 600°C (MBC) and by batch-wise hydrothermal carbonization at 210°C (HTC), and used as soil amendments. The plant biomass, plant nutrient concentration, nodule numbers, leghemoglobin (Lb) content, soil enzyme activities, and nutrient contents of the grown chickpeas were examined. Our results indicated that plant root and shoot biomass, the acquisition of N, P, K, and Mg, soil nutrient contents, soil alkaline and acid phosphomonoesterases, and proteases were significantly increased by HTC char application in comparison to MBC char under both well-watered and drought conditions. Furthermore, the application of both biochar types caused an increase in nodule number by 52% in well-watered and drought conditions by improving the symbiotic performance of chickpea with Mesorhizobium ciceri. Rhizobial inoculation combined with HTC char showed a positive effect on soil FDA activity, proteases and alkaline phosphomonoesterases under well-watered and drought conditions compared to the control or MBC char-amended soils. This concept, whereby the type of producing biochar plays a central role in the effect of the biochar, conforms to the fact that there is a link between biochar chemical and physical properties and enhanced plant nutrient acquisition, symbiotic performance and stress tolerance.
