Enhanced phenanthrene biodegradation in soil by slender oat root exudates and root debris.
To investigate the mechanisms by which slender oat (Avena barbata Pott ex Link) enhances phenanthrene biodegradation, we analyzed the impacts of root exudates and root debris on phenanthrene biodegradation and degrader community dynamics. Accelerated phenanthrene biodegradation rates occurred in soils amended with slender oat root exudates as well as combined root debris + root exudate as compa...
متن کاملArtificial root exudates and soil organic carbon mineralization in a degraded sandy grassland in northern China
Plant root exudates contain various organic and inorganic components that include glucose, citric and oxalic acid. These components affect rhizosphere microbial and microfaunal activities, but the mechanisms are not fully known. Studies concerned from degraded grassland ecosystems with low soil carbon (C) contents are rare, in spite of the global distribution of grasslands in need of restoratio...
متن کاملTobacco Rotated with Rapeseed for Soil-Borne Phytophthora Pathogen Biocontrol: Mediated by Rapeseed Root Exudates
Black shank, caused by Phytophthora parasitica var. nicotianae, is a widespread and destructive disease of tobacco. Crop rotation is essential in controlling black shank. Here, we confirmed that rotating black shank-infested fields with rapeseed (Brassica napus) suppressed the incidence this disease. Further study demonstrated that rapeseed roots have a strong ability to attract zoospores and s...

متن کاملSoil Ecological Safety Evaluation for Bivalent Transgenic Cotton Plants: Root Exudates versus Soil Enzyme Activities and Soil Microbial Diversity
Pot experiments were conducted to assess the possibly adverse effect of transgenic Btand CpTI-cotton (Bacillus thuringiensis and cowpea trypsin inhibitor cotton) on soil ecosystem. Soil enzymes activities and microbial molecular community and diversity based on 16sand 18s-PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) profiles were determined by adding root exudate...
