The Emergence of Endophytic Microbes and Their Biological Promise

Strobel, Gary A. (2018-05)

As is true with animal species, plants also have an associated microflora including endophytes as well as microbes associated with the phyllosphere and rhizosphere (plant surfaces) and this is considered the plant microbiome. ...

Antifungal Activities of Volatile Secondary Metabolites of Four Diaporthe Strains Isolated from Catharanthus roseus

Yan, Dong-Hui; Song, Xiaoyu; Li, Hongchang; Luo, Tushou; Dou, Guiming; Strobel, Gary (2018-05)

Four endophytic fungi were isolated from the medicinal plant, Catharanthus roseus, and were identified as Diaporthe spp. with partial translation elongation factor 1-alpha (TEF1), beta-tubulin (TUB), histone H3 (HIS), ...

A large-scale multiomics analysis of wheat stem solidness and the wheat stem sawfly feeding response, and syntenic associations in barley, Brachypodium, and rice

Biyiklioglu, Sezgi; Alptekin, Burcu; Akpinar, B. Ani; Varella, Andrea C.; Hofland, Megan L.; Weaver, David K.; Bothner, Brian; Budak, Hikmet (2018-02)

The wheat stem sawfly (WSS), Cephus cinctus Norton (Hymenoptera: Cephidae), is an important pest of wheat and other cereals, threatening the quality and quantity of grain production. WSS larvae feed and develop inside the ...

Domestication of Pea (Pisum sativum L.): The Case of the Abyssinian Pea

Weeden, Norman F. (2018-04)

Phylogenetic relationships of the Abyssinian pea (Pisum sativum ssp. abyssinicum) to other subspecies and species in the genus were investigated to test between different hypotheses regarding its origin and domestication. ...

Acute Toxicity of Permethrin, Deltamethrin, and Etofenprox to the Alfalfa Leafcutting Bee

Piccolomini, Alyssa M.; Whiten, Shavonn R.; Flenniken, Michelle L.; O'Neill, Kevin M.; Peterson, Robert K. D. (2018-05)

Current regulatory requirements for insecticide toxicity to nontarget insects focus on the honey bee, Apis mellifera (L.; Hymenoptera: Apidae), but this species cannot represent all insect pollinator species in terms of ...

Halophytes-associated endophytic and rhizospheric bacteria: diversity, antagonism and metabolite production

Bibi, Fehmida; Strobel, Gary A.; Naseer, Muhammad I.; Yasir, Muhammad; Khalaf Al-Ghamdi, Ahmed A.; Azhar, Esam I. (2018-02)

In Saudi Arabia, halophytes occupy tidal and intertidal forest ecosystems. They and their associated microflora have immense potential to yield novel and important useful natural products. Three halophytes (Avicennia marina, ...

Inocybe praetervisa group – A clade of four closely related species with partly different geographical distribution ranges in Europe

Larsson, Ellen; Vauras, Jukka; Cripps, Cathy L. (2018-07)

Sequence data from a broad geographical region and different habitats show that the Inocybe praetervisa clade is comprised of four closely related species. These species of section Marginatae are characterized by having ...

Scorched Earth: Suillus colonization of Pinus albicaulis seedlings planted in wildfire-impacted soil affects seedling biomass, foliar nutrient content, and isotope signatures

Jenkins, Martha L.; Cripps, Cathy L.; Gains-Germain, Leslie (2018-04)

Aims In western North America ectomycorrhizal fungi are critical to establishment of conifers in low nitrogen soils. Fire can affect both ectomycorrhizal fungi and soil properties, and inoculation with ectomycorrhizal ...

Sporocarp δ15N and use of inorganic and organic nitrogen in vitro differ among host-specific suilloid fungi associated with high elevation five-needle pines

Antibus, Robert K.; Hobbie, Erik A.; Cripps, Cathy L. (2018-07)

Widespread decline of whitebark and limber pines in the northern Rocky Mountains (USA) has created an imperative to understand functional diversity in their ectomycorrhizal associates. Because suilloid fungi are likely ...

Plant cover associated with aboveground net primary productivity (ANPP) mediates insect community composition in steppes of Northwest China

Zihua, Zhao; Reddy, Gadi V. P.; Wei, Shuhua; Zhu, Mengmeng; Zhang, Kaiyang; Yu, Hongqian; Wang, Zhanjun; Jiang, Qi; Zhang, Rong (2018-03)

Temperate steppe is one of the most important natural habitats for the conservation of arthropod and bird biodiversity across the Eurasian Tectonic Plate. Since 1950, fragmentation of the steppe habitat has caused a loss ...

Climate Change Perceptions and Observations of Agricultural Stakeholders in the Northern Great Plains

Grimberg, Bruna; Ahmed, Selena; Ellis, Colter; Miller, Zachariah; Menalled, Fabian (2018-05)

Communities reliant on subsistence and small-scale production are typically more vulnerable than others to disasters such as earthquakes. We study the earthquakes that struck Nepal in the spring of 2015 to investigate their ...

Competition between cheatgrass and bluebunch wheatgrass is altered by temperature, resource availability, and atmospheric CO2 concentration.

Larson, Christian D.; Lehnhoff, Erik A.; Noffsinger, Chance; Rew, Lisa J. (2017-12)
