To date, many rhizosphere microbiome studies and growth chambers systems focus on the impact of plant developmental stage, genotype and soil type on microbial composition and function . On the other hand, predation as a driver in the rhizosphere microbiome remains understudied. For instance, protists are abundant in the soil and are active consumers of …

Mortality was determined using a generalized linear model with a binomial family
Interestingly, many chemicals used by humans, which are not intended for use on microbial communities, have been shown to affect microbes. For example, caffeine, a common mental stimulant, alters biofilm respiration, and an antihistamine, diphenhydramine, has been demonstrated to modify the microbial community and respiration of lake biofilms. Because of unexpected pharmaceutical effects, it is …

A previous large-scale proteomics study in Arabidopsis also found OPT3 at the plasma membrane
We present evidence suggesting that this Cd over-accumulation may be the result of an enhanced transport of Cd through the plant, making opt3-2 a suitable background for studying long-distance transport of non-essential heavy metals. We further show that OPT3 is targeted to the plasma membrane and is preferentially expressed in the phloem. The Fe/Zn/Mn uptake transporter …
Interand intraspecific variations in traits that could affect C dynamics are considered
Microscopic analysis showed that 75% TP-Effluent and 50% TP-Effluent cultures had the highest cell densities . The TP-Effluent and 25% TP-Effluent cultures more closely resembled the negative control TP cultures, with poor growth relative to the other cultures. Over longer growth periods, there could be a larger difference between the different acetate concentration, but for the …
Extending through both reservoirs was a tube system consisting of a water lift and an air-line
ITNI was originally utilized to assess nitrogen deposition in agriculturally influenced ecosystems . Agricultural plants and cultivated crop species such as corn, rye, and wheat among others, have traditionally been utilized as ITNI study species. Additionally, the ecosystems under investigation were heavily influenced by applied nitrogen fertilizer. The latest investigation into ITNI, as of 2014, …
All of the metabolites proposed for A. thaliana cells were detected in the cucumber seedlings
N4- acetylsulfamethoxazole was detected in A. thaliana cells and confirmed using its authentic standard. The glucose and glutathione conjugates were detected by comparing the exact mass and fragmentation patterns to proposed spectra libraries for each compound . However, observed difference in the fragmentation patterns indicated that conjugation location differed from in those observed for human …
Plants also respond to P starvation by utilising alternative metabolic pathways
For P acquisition, the PHT gene family controlling P transport provides several candidate genes. In Arabidopsis, the PHTgenes that encode phosphate transporters responsible for transport of P anions are well characterised and are grouped into four families . PHT proteins other than PHT1 are involved in the uptake, distribution and remobilisation of P within the …

Solutions Farm’s current co-manager is a graduate of the program
Considering the social factors that shape access to opportunities brings up notions of spatial justice and the idea that rights and opportunities are not evenly distributed. Spatial justice would require space to be reorganized and reconceptualized “to promote equal access to opportunities, foster participation in decision-making, and encourage different ways of being in space” . …

The average grain Zn concentration of potting mix-grown control plants was similar to that of field-grown wheat
In Fe- and Zn-withholding treatments, root mineral content and concentration decreased substantially in both lines. Roots of all lines and treatments continued to grow during grain fill, and were larger at grain maturity than at anthesis, making calculation of remobilization by subtraction impractical. Despite the lack of significant net Fe and Zn remobilization from the total …
Dry weight data were analyzed in R using ANOVA and linear mixed-effect modeling
The grid was placed into a tank just large enough to hold the grid, and 20 L of hydroponic solution was used per tank. Genotypes were randomly assigned to positions in each cone-tainer grid using the sample and matrix functions in R . Aeration was supplied to each tank with an aquarium pump and two …
