Soil microbial community responses to multiple experimental climate change drivers.
Researchers agree that climate change factors such as rising atmospheric [CO2] and warming will likely interact to modify ecosystem properties and processes. However, the response of the microbial communities that regulate ecosystem processes is less predictable. We measured the direct and interactive effects of climatic change on soil fungal and bacterial communities (abundance and composition...
متن کاملResponses of soil microbial processes and community structure to tillage events and implications for soil quality
The short-term responses of soil microbial processes and community structure to perturbation constitute one aspect of soil quality. Such responses are often associated with an increase in the emissions of greenhouse gases (i.e., CO2, NO, or N2O) and the accumulation and potential loss of nitrate by leaching. Here we describe our recent work on responses of soil carbon and nitrogen dynamics, mic...
متن کاملMycorrhizal trifoliate orange has greater root adaptation of morphology and phytohormones in response to drought stress
Plant roots are the first parts of plants to face drought stress (DS), and thus root modification is important for plants to adapt to drought. We hypothesized that the roots of arbuscular mycorrhizal (AM) plants exhibit better adaptation in terms of morphology and phytohormones under DS. Trifoliate orange seedlings inoculated with Diversispora versiformis were subjected to well-watered (WW) and...
متن کاملSoil fungal community responses to global changes
The seasonal dynamics of soil fungal and bacterial communities are important for understanding the future ecosystem responses to global change due to their role in nutrient cycling and organic matter decomposition. After fourth year of increased temperature, extended drought and elevated CO2, soil samples were collected during one year to gain insight into how these treatments affected seasonal...
متن کاملPhysiological responses of two wheat cultivars to soil drought.
Young plants of the two wheat cultivars Katya and Prelom, differing in their reaction to drought in the field, were grown in soil in pots, and their water status was assessed as well as the intensity of gas exchange, chlorophyll fluorescence, and accumulation of compatible solutes and hydrogen peroxide after 7 days of dehydration. It was established that cv. Katya displayed markedly better tole...
