Hydrogen sulfide alleviates aluminum toxicity in barley seedlings
Aluminum (Al) toxicity is one of the major factors that limit plant growth. Low concentration of hydrogen sulfide (H2S) has been proven to function in physiological responses to various stresses. The objective of...

Identifying the species of copper that are toxic to plant roots in alkaline nutrient solutions
The pH of the growth medium influences Cu speciation in solution, the negativity of plasma membrane (PM) surface potential, and hence the rhizotoxicity of Cu.

Plant species effects on soil carbon and nitrogen dynamics in a temperate steppe of northern China
We evaluated plant species effects on soil carbon (C) and nitrogen (N) dynamics in a steppe ecosystem of northern China. In two subsequent years, we measured soil properties in the top 10 cm of the soil under ...

Evaluating mechanisms for plant-ion (Ca2+, Cu2+, Cd2+ or Ni2+) interactions and their effectiveness on rhizotoxicity
Electrical properties of plant cell membranes (CMs) provide a new avenue for exploring the mechanisms of plant-ion interactions and the biotic effects of ions. The modulating effect of Ca2+ on rhizotoxicity of me...

Establishment of Elymus natans improves soil quality of a heavily degraded alpine meadow in Qinghai-Tibetan Plateau, China
Elymus natans is a dominant native species widely planted to restore the heavily degraded alpine meadows in Qinghai-Tibetan plateau. The objective of this study was to determine how E. natans establishment affect...

Quantification of N2O fluxes from soil–plant systems may be biased by the applied gas chromatograph methodology
With regard to measuring nitrous oxide (N2O) emissions from biological sources, there are three most widely adopted methods that use gas chromatograph with an electron capture detector (GC–ECD). They use: (a) nit...

Genetic variability for root hair traits as related to phosphorus status in soybean
Plant root hairs are believed to be very important for phosphorus (P) uptake from the soil by expanding the absorptive surface area of the root and increasing the soil volume explored by the roots, but genetic...
