Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

open access: yesAdvanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Effects of Rhizobium tropici, R. etli, and R. leguminosarum bv. phaseoli on nod Gene-Inducing Flavonoids in Root Exudates of Phaseolus vulgaris

open access: yesMolecular Plant-Microbe Interactions, 1997
Flavonoids play an important role as signal molecules in the early stages of the legume-Rhizobium symbiosis. The flavonoid content in root exudates of individual seedlings of Phaseolus vulgaris cv. Rab39 was determined by a sensitive method that combines

Requirement of a Plasmid-Encoded Catalase for Survival of \u3cem\u3eRhizobium etli\u3c/em\u3e CFN42 in a Polyphenol-Rich Environment [PDF]

open access: yes, 2008
Nitrogen-fixing bacteria collectively called rhizobia are adapted to live in polyphenol-rich environments. The mechanisms that allow these bacteria to overcome toxic concentrations of plant polyphenols have not been clearly elucidated.

Arabidopsis ABCG14 is essential for the root-to-shoot translocation of cytokinin. [PDF]

open access: yes
Cytokinins are phytohormones that induce cytokinesis and are essential for diverse developmental and physiological processes in plants. Cytokinins of the trans-zeatin type are mainly synthesized in root vasculature and transported to the shoot, where ...

A practical and low cost microbiotest to assess the phytotoxic potential of growing media and soil [PDF]

open access: yes, 2008
For routine toxicity testing of composts and growing media, two different types of assays are usually applied. One approach is the use of growing trials in pots with various mixtures of the material.

Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

open access: yesAdvanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.

Characterization of black oat root exudates in the presence of interspecific weed species and intraspecific neighbors, and their effects on root traits

open access: yesFrontiers in Plant Science
IntroductionCover crops, like black oat, suppress weeds in multiple ways, e.g. by resource competition and/or root exudates, but very little is known about their root exudate composition.MethodsRoot exudates from black oat interacting with intra- (black ...

Agricultural management and plant selection interactively affect rhizosphere microbial community structure and nitrogen cycling. [PDF]

open access: yes, 2019
BACKGROUND:Rhizosphere microbial communities are key regulators of plant performance, yet few studies have assessed the impact of different management approaches on the rhizosphere microbiomes of major crops.

Influence of different iron availability on phosphoenolpiruvate carboxilase and malate dehydrogenase in roots of maize (Zea Mays L.) plants grown under iron deficiency [PDF]

open access: yes, 2010
The effect of the different nitrate availability on some enzymatic activities has been evaluated in iron deficient and iron sufficient maize plants (Zea mays L.).

Wearable Battery‐Free Electrotherapy of Smartsensors for Wound Healthcare

open access: yesAdvanced Science, EarlyView.
Herein, we propose a simple strategy for integrating battery‐free electrotherapy wound dressings with wound sensors. Solid‐state supercapacitors constructed by PMAB with cross‐linked interpenetrating network provide energy for electrotherapy. Meanwhile, excellent mechanical sensing performance of wound dressing was used for wound assessment.
