Influence of Soil Moisture on Root Colonization of Glyphosate-Treated Soybean by <i>Fusarium</i> Species
The widespread use of glyphosate-resistant (GR) cropping systems may impact rhizosphere microbial associations and crop productivity. It was previously reported that glyphosate accumulation in the rhizosphere may stimulate colonization of soybean [Glycine max (L.) Merr.] roots by soilborne Fusarium. Field studies often reveal inconsistent root colonization by Fusarium, especially during growing...
متن کاملInfluence of Elevated Atmospheric Carbon Dioxide on Transcriptional Responses of Bradyrhizobium japonicum in the Soybean Rhizoplane
Elevated atmospheric CO2 can influence the structure and function of rhizoplane and rhizosphere microorganisms by altering root growth and the quality and quantity of compounds released into the rhizoplane and rhizosphere via root exudation. In these studies we investigated the transcriptional responses of Bradyrhizobium japonicum cells growing in the rhizoplane of soybean plants exposed to ele...
متن کاملLow Light Availability Alters Root Exudation and Reduces Putative Beneficial Microorganisms in Seagrass Roots
Seagrass roots host a diverse microbiome that is critical for plant growth and health. Composition of microbial communities can be regulated in part by root exudates, but the specifics of these interactions in seagrass rhizospheres are still largely unknown. As light availability controls primary productivity, reduced light may impact root exudation and consequently the composition of the root ...
متن کاملUpdate on Root Exudation and Rhizosphere Biology Root Exudation and Rhizosphere Biology
Our understanding of the biology, biochemistry, and genetic development of roots has considerably improved during the last decade (Smith and Fedoroff, 1995; Flores et al., 1999; Benfey and Scheres, 2000). In contrast, the processes mediated by roots in the rhizosphere such as the secretion of root border cells and root exudates are not yet well understood (Hawes et al., 2000). In addition to th...
متن کاملRoot-induced changes in nutrient cycling in forests depend on exudation rates
(1) While it is well-known that trees release carbon (C) to soils as root exudates, the factors that control the magnitude and biogeochemical impacts of this flux are poorly understood. (2) We quantified root exudation and microbially-mediated nutrient fluxes in the rhizosphere for four ~80 year-old tree species in a deciduous hardwood forest, Indiana, USA. We hypothesized that trees that exude...
