Soil amendments from recycled waste differently affect CO₂ soil emissions in restored mining soils under semiarid conditions.

J Environ Manage 2021 Jun 10;294:112894. Epub 2021 Jun 10.

Department of Agronomy & Center for Intensive Mediterranean Agrosystems and Agri-food Biotechnology (CIAIMBITAL), University of Almeria, E-04120, Almería, Spain. Electronic address:

Drylands affected by serious disturbances such as mining activities lose their vegetation cover and organic soil horizons, becoming CO emissions sources. Applications of organic amendments could be a good restoration solution that favours vegetation establishment and soil carbon sequestration; however, they are also associated with CO₂ emissions. Experimental plots with different organic amendments (sewage sludge, garden and greenhouse vegetable composts, and mixtures of both) and unamended soils were installed in a quarry in southeast Spain.

Exogenous melatonin reduces water deficit-induced oxidative stress and improves growth performance of Althaea rosea grown on coal mine spoils.

Environ Sci Pollut Res Int 2021 Jun 5. Epub 2021 Jun 5.

College of Economics and Management, Northwest A&F University, Yangling, 712100, Shaanxi, China.

Coal mining activities are responsible for significant land degradation and often long-term irreversible effects on ecosystem functioning. To better understand how coal mined sites could be re-vegetated and ecosystem functioning restored, we address the role of the signalling hormone melatonin, which controls plant growth and development under adverse environmental conditions. We assessed the effects of exogenous melatonin on the plant species Althaea rosea by measuring morphological growth attributes, photosynthetic efficiency, reactive oxygen species (ROS)-induced oxidative damage and antioxidant defence developed by the seedlings when grown on coal-mined spoils under various water regimes.

Chemotropic Assay for Testing Fungal Response to Strigolactones and Strigolactone-Like Compounds.

Methods Mol Biol 2021 ;2309:105-111

Department of Agricultural Sciences, University of Naples Federico II, Naples, Italy.

Current knowledge on the mechanism of strigolactones (SLs) as signaling molecules during specific interactions in the rhizosphere is mainly related to the control of germination of parasitic weed seeds and hyphal branching of arbuscular mycorrhizal fungi. Thus, the role of plant secreted SLs in regulating the growth and development of root-colonizing fungi still remains controversial. Fusarium oxysporum can sense and respond to extracellular signals through oriented germ tube emergence and redirectioning of hyphal growth toward gradients of nutrients, sex pheromones, or plant root exudates.
