Although sold commercially as myco-insecticides, naturally occurring soil borne entomopathogenic fungi (EPF) pose a unique opportunity for regulating soil-dwelling insect herbivore populations via conservation biological control. Plant identity has a significant effect on soil borne fungi, which may includee EPF. We asked whether the choice of covercrops could affect the diversity and infectivity of

This study aimed to evaluate the influence of arbuscular mycorrhizal fungi on the growth and production of capitula and essential oil of chamomile plants, under different growth conditions. The symbiosis between fungi of the phylum Glomeromycota and plant roots may cause changes in secondary metabolism, including the synthesis of essential oils. Increasing biomass production associated with gains in

The viability of the Golden Pothos (Epipremnum aureum) plants in different formulations of engineered growth media were evaluated for application in plant-based air filtration systems. To enhance filtration capability, the growth media was engineered to improve toxin capture ability with the aim of maintaining a plant-friendly environment. The growth media used in this study was a hydroponic media

The coarse mint (Plectranthus amboinicus Lour.) is a medicinal plant that produces essential oil; however, it is still little studied the effects of effects of arbuscular mycorrhizal fungi species on growth and essential oil content and its composition in P. amboinicus. Therefore, this study aimed to evaluate Rhizophagus clarus and Claroideoglomus etunicatum under low and high phosphorus conditions

Iron biofortification of crops, like wheat, is an attractive strategy to cope with iron deficiency causing hidden hunger. Several recent studies dissected the genetics controlling iron concentrations in wheat grain, and expanded our understanding of iron accumulation in wheat grains. However, successful breeding of iron-rich wheat cultivar is limited based on plant genetics. Along with the wide appreciation

White root rot disease caused by Rigidoporus microporus results in major economic loss to rubber plantation in all rubber growing countries including Malaysia. This glasshouse trial was conducted to explore the potential of single and co-inoculation of Enterobacter sp. UPMSSB7 and arbuscular mycorrhizal fungi (Glomus mosseae) with silicon for white root rot disease suppression and plant growth promotion

Flavonoids produced by roots are secondary metabolites involved in the induction of nod genes in rhizobial cells and nodule organogenesis. We describe the development and quality control of a new formulation for soybean (Glycine max (L.) Merr.) based on Bradyrhizobium elkanii cells grown in a culture medium containing isoflavones. As opposed to B. japonicum, the performance of B. elkanii pre-incubated

Cyanobacteria, a group of N2 fixing bacteria, and some species of them are free-living or associated with other bacteria, such as Azospirillum. Their association promotes the growth and productive performance of maize (Zea mays), showing variable responses according to the maize hybrid used. Thus, the aim of this study was to evaluate the effects of inoculation and co-inoculation of the Anabaena cylindrica

The utilization of appropriate preparations of plant growth-promoting fungi (PGPF) is one of the most promising trends for inducing plant resistance against a pathogen. However, not much is known about their mechanisms. Herein, the goal of this study was to present more information on this matter. The isolated rhizosphere fungi Aspergillus falvus, Aspergillus niger, Penicillium citrinum, Penicillium

The root knot nematode (Meloidogyne spp.) is a widely distributed phytoparasite and causes production losses in soybeans. Therefore, the aim of the present study was to evaluate the isolates of Purpureocillium lilacinum (Simbiose®), Claroideoglomus etunicatum and Rhizophagus clarus as possible biocontrol agents for Meloidogyne incognita. The greenhouse treatments consisted of six distinct formulations

Plants from phosphorus (P) limited environments have developed various strategies for acquiring P from the soil, and for maintaining P homeostasis within the plant. We analyzed the mechanisms of phosphorus acquisition used by the grass Sporobolus airoides-rhizosphere microbiota during two years with contrasting annual rainfall in an extreme P-oligotrophic ecosystem. We determined arbuscular mycorrhizal

Endophytic plant growth promoting bacteria are of great interest since the ability to colonize the internal tissues of plants gives it an adaptive advantage. To confer any beneficial effect on the plant, bacteria must present a successful colonization and thus be competent in the rhizosphere and finally infect internal tissues. In this sense, bacterial motility is an essential property involved in

Phytonematodes cause great losses to agricultural production. The magnitude of their economic impact is directly related to management practices, with the hypothesis that high nematode populations can also be found inside and outside symptomatic patches, and that they correlate with soil properties. This study examined the relationship of soil chemical properties and texture with phytonematode populations

Salinity stress adversely affects root nodulation symbiotic relationships, and ultimately the nitrogen fixation capacity and the growth and yield of leguminous plants. Improving growth and biological nitrogen fixation of leguminous plants grown on salt–affected soils are considered to be a striking challenge. Most of the findings reveal that co–inoculation of legumes with salt–tolerant non–rhizobial

The efficacy of a liquid formulation of “PGPR mix-I″ amended with 15 mM treahoalose, and a talc based formulation of the same were tested for plant growth promotion in amaranthus crop in sterilized soil under glass house conditions. The seven treatments included 100% NPK as per Kerala Agricultural University recommendation as chemical fertilizer alone, talc based or liquid formulation of PGPR mix–I

Arbuscular mycorrhizal fungi (AMF) play a pivotal role in ecological restoration. To date, indigenous AMF remain unexplored but could be a potential resource for successful restoration programs. In this study, we evaluated the infectivity of AMF of five degraded oasis soils in Morocco (Marrakesh, Tafilalet, Draa, Tata-Guelmim and Figuig). Our data showed that mycorrhizal parameters; AMF spore number

In tree-based intercropping systems, roots of trees and crops are interacting and could influence ecosystem services provided by soil microorganisms. Here, the analysis of diversity of arbuscular mycorrhiza fungi (AMF) associated with roots of walnut and maize reveals differences. Of interest, Funneliformis genus is mainly associated with maize roots, and one OTU related to an uncultured Glomus, might

Rhizobia can colonize the roots of grasses in the Brazilian semiarid region; however, studies to isolate these bacteria for growth promotion of maize via unconventional isolation approaches have not been conducted. This study aimed to isolate, characterize (biochemically and molecularly) and assess the potential of cowpea nodulating/maize associated rhizobia for plant growth promotion. Extracts of

Bacteria of the Pseudomonas genus have been widely studied due to their antagonistic potential against a diverse group of fungal and bacterial phytopathogens, and their competence to colonize different plant tissues. We have isolated a rhizospheric pseudomonad that produced a black pigment, which is not a widespread trait within this genus. We confirmed that the isolate belonged to the P. putida complex

Our objectives were to (1) monitor the proliferation of the biocontrol agent (BCA) Fusarium oxysporum f. sp. strigae strain "Foxy-2", an effective soil-borne BCA against the parasitic weed Striga hermonthica, in the rhizosphere of maize under different agro-ecologies, and (2) investigate its impact on indigenous rhizosphere fungal community abundance and composition. Field experiments were conducted
