Plants interact closely with microbes, which are partly responsible for plant growth, health, and adaptation to stressful environments. Engineering the plant-associated microbiome could improve survival performance in environments such as contaminated soils. Here, willow cuttings were planted into highly petroleum-contaminated soils that had been gamma-irradiated subjected one of four treatments: inoculation rhizosphere soil from a grew well (LA) or sub-optimally (SM) bulk died (DE) no (CO)....
The interaction between plants and microorganisms, which is the driving force behind decontamination of petroleum hydrocarbon (PHC) contamination in phytoremediation technology, poorly understood. Here, we aimed at characterizing variations plant compartments microbiome two willow cultivars growing contaminated soils. A field experiment was set-up a former petrochemical Canada after seasons, bulk soil, rhizosphere roots, stems samples (Salix purpurea cv. FishCreek, Salix miyabeana SX67)...
Arsenic (As) is a ubiquitous toxic element adversely affecting human health. Microbe-mediated cycling of As largely mediated by detoxification and energy metabolism in microorganisms. We here report the development novel high-throughput qPCR (HT-qPCR) chip (AsChip) for comprehensive profiling genes involved microbial (here collectively termed "As genes"). AsChip contained 81 primer sets targeting 19 16S rRNA gene as reference gene. Gene amplicon sequencing showed high identity (>96%) newly...
Deep-rooted plants can obtain water and nutrients from the subsoil, making them resilient to climatic changes. Plant growth health may depend on interactions with root-associated bacteria but composition assembly dynamics of deep-root-associated bacterial communities are unknown, as is their ability supply nitrogen (N). Here, we investigated three deep-rooted perennial crops—lucerne ( Medicago sativa), intermediate wheatgrass Thinopyrum intermedium), rosinweed Silphium integrifolium)—grown...
Abstract Deep-rooted plants can obtain water and nutrients from the subsurface, making them more resilient to climatic changes such as drought. In addition, deeper root network also allow recruit bacteria a larger reservoir in soil. These might contribute nutrient acquisition provide other plant beneficial traits plant. However, deep rhizosphere communities’ compositions their assembly dynamics are unknown. Here, we show, using three perennial crops, Kernza, lucerne rosinweed, grown 4 m...
