ABSTRACT Arbuscular mycorrhizal fungi (AMF) was considered as a biotechnological tool for plant stress tolerance improvement and degraded ecosystem restoration. However, the variations in the effects of AMF species and abundance on plant performance under stress condition have to be still investigated. The study was conducted to evaluate the mechanisms of five AMF species, single or mixture, on Leymus

ABSTRACT In this study, the impacts of exogenous melatonin on freezing stress mitigation in pistachio (Pistacia vera L.) seedlings (30-days old) were investigated. Our results showed that in pistachio seedlings under freezing stress antioxidant enzyme activity, malondialdehyde (MDA) hydrogen peroxide (H2O2), electrolyte leakage, chlorophyll degradation, proline and soluble sugar and γ-aminobutyric

ABSTRACT Plants can be severely affected by heat stress due to rapid environmental changes. Use of endophytic fungi is a new tool to protect crops from the environmental stresses. Here we claim a potent endophyte isolated from Sonchus asper L. The aim was to explore the stress adaptive mechanism of sunflower and soybean mediated by Aspergillus niger (SonchL-7) under high temperature. Inoculation with

ABSTRACT Plant-specific CDF genes encode a class of transcription factors which play crucial roles in plant flowering, especially in photoperiod-regulated flowering. But little is known about the potential functions of MdCDFs during flower induction in apple. In this study, 11 putative MdCDFs were identified and named systematically. Bioinformatic analysis revealed a functional and structural similarity

ABSTRACT Facilitation by nurse plants likely increases from outside the canopy to the center of the canopy as stresses decrease towards the center of the canopy. These stress gradients may be important in controlling plant distributions, with stress-tolerant species specializing outside the canopy or at the canopy edge, and stress intolerant species specializing at the center of the canopy. We tested

ABSTRACT Green bean is one of the widely cultivated crops in developing countries. However, its cultivation is constrained by low soil fertility. A field experiment was conducted to evaluate the effect of LBS and N rates on soil physico-chemical properties and yield of green bean at Hawassa, Ethiopia. Four levels of LBS (0, 20.6, 41.2 and 61.8 m3/ha) and four N levels (0, 20.5, 41 and 61.5 kg/ha) were

ABSTRACT Early ripening is an important desirable attribute for fruit crops. ‘Tiangong Moyu’, a bud mutant of the grape cultivar ‘Summer Black’ (Vitis vinifera L.× Vitis labrusca L.), ripens nearly 10 days earlier and shows earlier increase in fresh weight, sugar accumulation, and color change and faster decrease in titratable acid than ‘Summer Black’. To identify the genes controlling early fruit

ABSTRACT WDR proteins in plants regulate multiple aspects of plant growth and development, as well as plant responses to environmental stimuli. Here, we report the identification of AIW1 (ABA-induced WD40-repeat 1) and AIW2 as novel regulators of salt responses in Arabidopsis. RT-PCR results show that the expression of AIW1 and AIW2 were induced by ABA. Transfection assays in protoplasts show that

ABSTRACT In this study, two bread wheat (Triticum aestivum L.) cultivars, Pishgam (drought-tolerant) and Shahryar (drought-sensitive), were grown in the greenhouse under control and moisture stress conditions. Based on phenological and morpho-physiological results, Pishgam was confirmed as a moisture stress tolerant cultivar. In the fallowing, at the start of heading time, its treated and untreated

ABSTRACT Volatile organic compounds displayed biological activities on a wide range of organisms, including plants and microbes. Investigating their role in the plant-microbe interaction processes occurring in the soil is challenging. By simulating belowground communication conditions between plant and microbes, in this study, we aimed to investigate the effects of the volatiles emitted by Serratia

ABSTRACT This study aimed to investigate the interaction effects of iron oxide nanoparticle (nα-Fe2O3) and its bulk counterpart (bα-Fe2O3) with and/or without citrate interaction on germination and seedling growth of Oenothera biennis L. We prepared buffered suspensions of nα-Fe2O3 and bα-Fe2O3 at 4 levels (0, 0.2, 0.5 and 1 g.L−1). The nα-Fe2O3 increased 89.17% germination percentage, 53.36% germination

ABSTRACT Since the discovery of Berberis and Mahonia species. as aecial hosts of the wheat stripe rust pathogen, Puccinia striiformis Westend. f. sp. tritici Eriks. (Pst), their possible role in generating new races of Pst through sexual reproduction, has become a hot issue in the agricultural scientific community. To date, all the investigations about the role of alternate hosts in the occurrence

ABSTRACT Flooding is an important limiting factor for plant growth and development. Recent studies have shown that endophytic fungi symbiotic with extreme environmental plants can help hosts resisting various stresses. Previously, a styrene antioxidant NFA (Z-N-(4-hydroxystyryl) formamide) in riparian endophytic Aspergillus fumigatus was reported to effectively improve drought resistance in rice. To

ABSTRACT Relatively little is known about the physiological significance of betalain pigments. To investigate a possible protective role for betalains (betacyanin), from UV-B irradiation, two cultivars of A. tricolor, Red-Leaf (RL) and Green-Leaf (GL) were obtained and VIGS method was used to produce isogenic derivatives of RL. Short-term responses to UV-B in the leaves were compared with and without

ABSTRACT The effect of a soil thermophilic bacteria (STB), Ureibacillus sp. 18UE/10 on the status of wheat plants was evaluated. A greenhouse assay was performed, mimicking scenarios of soil impoverishment and aridity, which included Rhizophagus irregularis, a crop enhancer AMF, for effect comparison. Treatments with strain 18, R. irregularis or both had no significant effect on biomass production

ABSTRACT The aim of this study was to investigate the optimum time for γ-aminobutyric acid (GABA) application to improve the yield and quality in fragrant rice. Pot and field experiments were conducted during 2016–17 with two fragrant rice cultivars (for pot experiment), and five fragrant rice cultivars (for field experiment) which were applied with five GABA levels i.e. no GABA application (CK), application

ABSTRACT Most flowering plants are visited by various pollinator insects. To understand floral specialization for pollinators, the relative importance of different flower visitors to the focal plant species should be revealed. In the present study, we observed the insects that visited the orchid Platanthera hologlottis throughout the day and night using interval timer photography to reveal the relative

ABSTRACT Drought is a major cause of the present decrease in crop yield and agricultural productivity around the globe. The disastrous effects of drought on plants call for a renewed concern on effective strategies to improve plant growth and yield under drought stress. This study was designed to evaluate the effectiveness of Arthrobacter arilaitensis and Streptomyces pseudovenezuelae to improve maize

ABSTRACT A detailed assessment of a pasture’s functioning based on soil properties characterization, floristic composition, and ‘functional summary’ by evaluating competitor–stress tolerator–ruderal (CSR) strategies is provided for a doline in Central Italian Alps. A floristic survey was carried out at 35 sampling points, representative of the main topographic features, soil and vegetation types; the
