no-choice preference of cerotoma trifurcata (coleoptera: chrysomelidae) to potential host plants of bean pod mottle virus (comoviridae) in better understand the naturally occurring host range of bean pod mottle virus (family comoviridae, genus comovirus, bpmv) and its principal vector cerotoma trifurcata (förster) (coleoptera: chrysomelidae), 18 field-collected perennial plant species were tested for the presence of bpmv. by using no-choice assays, we determined the preference of these plants by bean leaf beetle, by measuring their level of herbivory relative to soybean, glycine max (l.). new food hosts for adult bean leaf beetl ...200717598542
plant community richness and microbial interactions structure bacterial communities in soil.plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. we hypothesized that plant species and plant community diversity affect soil bacterial communities by setting the context in which bacterial interactions occur. specifically, we examined soil bacterial community composition and diversity in relation t ...201526236898
diffuse symbioses: roles of plant-plant, plant-microbe and microbe-microbe interactions in structuring the soil microbiome.a conceptual model emphasizing direct host-microbe interactions has dominated work on host-associated microbiomes. to understand plant-microbiome associations, however, broader influences on microbiome composition and functioning must be incorporated, such as those arising from plant-plant and microbe-microbe interactions. we sampled soil microbiomes associated with target plant species (andropogon gerardii, schizachyrium scoparium, lespedeza capitata, lupinus perennis) grown in communities vary ...201424148029
effects of plant host species and plant community richness on streptomycete community structure.we investigated soil streptomycete communities associated with four host plant species (two warm season c4 grasses: andropogon gerardii, schizachyrium scoparium and two legumes: lespedeza capitata, lupinus perennis), grown in plant communities varying in species richness. we used actinobacteria-selective pcr coupled with pyrosequencing to characterize streptomycete community composition and structure. the greatest pairwise distances between communities were observed in contrasts between monocult ...201323013423
[flavonoids as medicines].although flavonoids have been used for a long time, many medical practitioners and pharmacists know very little about them. this article gives a few particulars of some flavonoids and plant extracts: rutin, water soluble derivatives of rutin, citroflavonoids, anthrocyanins, procyanidins, silymarin, ginkgo biloba, chrysanthellum indicum and lespedeza capitata.20062698952
rhizosphere bacterial communities associated with long-lived perennial prairie plants vary in diversity, composition, and structure.the goal of this research was to investigate the variation in rhizosphere microbial community composition, diversity, and structure among individual andropogon gerardii vitman (big bluestem) and lespedeza capitata michx. (bush clover). bacterial communities from the rhizosphere of 10 plants of each species (n = 20 plants total) were explored using a culture-independent pipeline. microbial communities associated with both host plants had high bacterial diversity within individual plant rhizospher ...201323826959
plant community richness mediates inhibitory interactions and resource competition between streptomyces and fusarium populations in the rhizosphere.plant community characteristics impact rhizosphere streptomyces nutrient competition and antagonistic capacities. however, the effects of streptomyces on, and their responses to, coexisting microorganisms as a function of plant host or plant species richness have received little attention. in this work, we characterized antagonistic activities and nutrient use among streptomyces and fusarium from the rhizosphere of andropogon gerardii (ag) and lespedeza capitata (lc) plants growing in communitie ...201728058470
growth responses, biomass partitioning, and nitrogen isotopes of prairie legumes in response to elevated temperature and varying nitrogen source in a growth chamber experiment.because legumes can add nitrogen (n) to ecosystems through symbiotic fixation, they play important roles in many plant communities, such as prairies and grasslands. however, very little research has examined the effect of projected climate change on legume growth and function. our goal was to study the effects of temperature on growth, nodulation, and n chemistry of prairie legumes and determine whether these effects are mediated by source of n.201222539505
stoichiometric response of nitrogen-fixing and non-fixing dicots to manipulations of co2, nitrogen, and diversity.human activities have resulted in increased nitrogen deposition and atmospheric co(2) concentrations in the biosphere, potentially causing significant changes in many ecological processes. in addition to these ongoing perturbations of the abiotic environment, human-induced losses of biodiversity are also of major concern and may interact in important ways with biogeochemical perturbations to affect ecosystem structure and function. we have evaluated the effects of these perturbations on plant bi ...200717106721
selection of rhizobia for prairie legumes used in restoration and reconstruction programs in minnesota.the inoculation of indigenous legumes used in revegetation and wetland reconstruction activities in minnesota presents problems not found in more traditional seedings. few studies have sought inoculant-quality rhizobia for the legumes involved or examined their interaction in an environment that involves a number of different legumes seeded simultaneously under initially adverse climatic conditions. in this note, we identify effective strains for astragalus canadensis, chamaecrista fasciculata, ...200415644916
therapeutic potential of temperate forage legumes: a review.the discovery of bioactive molecules from botanical sources is an expanding field, preferentially oriented to plants having a tradition of use in medicine and providing high yields and availability. temperate forage legumes are fabaceae species that include worldwide-important crops. these plants possess therapeutic virtues that have not only been used in veterinary and folk medicine, but have also attracted the interest of official medicine. we have examined here medicago sativa (alfalfa), trif ...201626507574
