“…These endophytes either as single strain or multi-strain inoculum have previously exhibited mutualistic behavior when added to other plant species including grasses, corn, rice, Douglas-fir and a variety of crop plants (Xin et al, 2009;Knoth et al, 2013;Knoth et al, 2014;Khan et al, 2012;Khan et al, 2015;DaSilveria et al, 2016). Combined application of endophytes can result in larger effects than those possible with individual inoculations (Knoth et al, 2013;Knoth et al, 2014;Rogers et al, 2012). In this study, the bacterial and fungal strains of different endophytes (Bacillus sp.…”

Increasing human population places pressure on agriculture. To feed this population, two time increase in the current wheat production is needed. Today agriculture is becoming input intensive with more reliance on synthetic fertilizers and agrochemicals to fulfil the feed demand of the growing numbers. Use of synthetic fertilizer since last few years is impacting the soil quality. In this scenario, the use of beneficial endophytic microbes is an attractive strategy to overcome the use of synthetic products. To investigate the effect of consortium application of endophytic bacteria and fungus on plant growth, grain yield moisture status, a pot experiment was conducted in different wheat lines. It comprised four treatments like control, application of bacterial strain Bacillus sp. MN54, fungal strain Trichoderma sp. MN6, and their consortium (Bacillus sp. MN54 + Trichoderma sp. MN6). The effect of consortium application was more prominent and significantly different from the sole application of bacteria and fungus. The results showed that with a consortium application of endophytic bacteria and fungus, there was 28.6, 4.3, -6.3 and -3.7% increases in flag leaf area, chlorophyll content, relative membrane permeability and water content respectively. Consortia of endophytic microbes also resulted in the yield enhancement through the betterment of various yield attributes like number of spikelet's, grains per spike and grain yield per plant (32.2, 25.8 and 30.8%, respectively). So, consortia of endophytic microbes can greatly promote the progress of plants in dry land agriculture and increase the yield in an environmentally sustainable way.

“…In this preliminary study, we chose a consortia of diazotrophic endophytes, originally isolated from poplar and willow trees [20][21][22], because they had shown robust growth-promoting activity with agricultural crops, grasses and poplar plants grown under abiotic stress [22,[39][40][41]. Our objective was to determine if these endophytes enhance the growth of Douglas-fir seedlings under nutrient-poor conditions.…”

Douglas-fir (Pseudotsuga menziesii) seedlings are periodically challenged by biotic and abiotic stresses. The ability of endophytes to colonize the interior of plants could confer benefits to host plants that may play an important role in plant adaptation to environmental changes. In this greenhouse study, nursery-grown Douglas-fir seedlings were inoculated with diazotrophic endophytes previously isolated from poplar and willow trees and grown for fifteen months in nutrient-poor conditions. Inoculated seedlings had significant increases in biomass (48%), root length (13%) and shoot height (16%) compared to the control seedlings. Characterization of these endophytes for symbiotic traits in addition to nitrogen fixation revealed that they can also solubilize phosphate and produce siderophores. Colonization was observed through fluorescent microscopy in seedlings inoculated with gfp-and mkate-tagged strains. Inoculation with beneficial endophytes could prove to be valuable for increasing the production of planting stocks in forest nurseries.
