This study was conducted on soybean (Glycine max L. Merr.) nodules to determine if exogenous NH3 exerts a controlling influence over nitrogenase activity through changes in nodule gas permeability (P), and if decreasing carbohydrate availability, as a result of low-light treatment, increases the sensitivity of root nodules to NH3. Nodulated root systems of intact plants were exposed to one of s...

The arbuscular mycorrhizal (AM) symbiosis is the association between fungi of the order Glomales (Zygomycetes) and the roots of terrestrial plants (Harley and Smith, 1983). Conservative estimates suggest that this ancient symbiosis, dating back to the early Devonian age (398 million years ago), affects approximately 90% of the Earth’s land plant species (Remy et al., 1994). This symbiosis is in...

Phytoremediation, an emerging cleanup technology for contaminated soils, groundwater, and wastewater that is both low-tech and low-cost, is defined as the engineered use of green plants (including grasses, forbs, and woody species) to remove, contain, or render harmless such environmental contaminants as heavy metals, trace elements, organic compounds, and radioactive compounds in soil or water...

Plant roots, which are essential for providing anchorage to the soil, acquiring mineral nutrients and water, and for synthesizing a plethora of metabolites, provide an excellent model for studying physiological, developmental, and metabolic processes at a systems level. The challenge to understand such processes has been compared with deciphering the principle of a radio by a reductionist appro...

Almost immediately after it was mooted as a descriptor for our current geological age, the Anthropocene came under sustained criticism. It said label projected unearned heroism onto humanity master of natural world, while downplaying culpability Global North unlocking ruinous potential industrialism and technology (Bonneuil & Fressoz, 2016; Haraway, 2015; Malm, Moore, 2015).
