The surface of the bubbles, as shown earlier, is proposed to contain adsorbed hydroxide ions arranged in rhomboid unit cells, and by vector addition it is clear that the least repulsion to oxygen molecule to diffuse through the hydroxide ions would be at the centre of each rhombus, which would be limited to a greatly …

Metal localization in A.murale roots was investigated with microtomography
Metal localization and elemental associations in plants were investigated with X-ray and electron microscopies and X-ray microtomography.Particular emphasis was placed on the phenomenon of ‘simultaneous hyper accumulation’and its relationship to metal co-tolerance.Metal localization and elemental associations in A.murale were investigated with SXRF, CMT, SEM-EDS and XAS.Two-dimensional SXRF images of A.murale leaves revealed a distinctive localization pattern for …

Prospective biology targets are those that are most mission-relevant and expensive
OsPRR95 corresponds to Arabidopsis PRR, AtPRR5 or AtPRR9.A report has revealed that triple mutant prr 9–11 prr 7–10 prr 5–10 Arabidopsis exhibit better salt, drought and cold tolerance than wild type, and thus suggested that PRR5, PRR7 and PRR9 are involved in the diurnal cold stress-initiating stress response by mediating the cyclic expression of stress …
Tungsten oxidenano particles were purchased from US Research Nanomaterials
These toxic elements can be bio-available to terrestrial and aquatic organisms, including crop plants, and could be further bio-accumulated via the food chain causing damage to humans.Since these metals cannot be degraded, current remediation approaches include excavation or capping, with a very high cost and damage to ecosystems.In many cases, these options are not economically …

Seed lectin genes of both pea and soybean are expressed at low levels in roots
Taken together, these data indicate that MsLEC1 and MsLEC2 genes, as well as the orthologous gene MaLEC, are expressed in the youngest cells of indeterminate nodules of both alfalfa and white sweetclover. Moreover, the genes that encode these soluble lectins are also expressed in root tips. MsENOD40 gene expression. We hypothesized that expressing the lectin transgenes would not …

The micro-scale of the channels limits the applications of these devices to young seedlings
Microfluidic platforms have also been successfully employed to study the interactions between the root, microbiome and nematodes in real time . In the systems, additional vertical side channels are connected perpendicularly to the main micro-channel to enable introduction of microorganisms and solutes to the roots in a spatially and temporally defined manner . A recent …
Several new incentive programs warrant future research to optimize their impact
Since 1984, farming and grazing lands have been converted to urban development at an average rate of 40,000 acres per year . At this rate, and considering the higher rate of emissions from urban versus agricultural land, slowing agricultural land conversion represents one of the largest opportunities for agriculture to contribute to California’s climate plan. …

The potential health and environmental impact of ENPs need to be understood
The first group includes four genes annotated as defense genes, a function that is likely not closely related with the observed phenotypes. This group includes TraesCS1B02G017500 and TraesCS1B02G0017600 , which encode proteins with NB-ARC and LRR domains characteristic of plant disease-resistance proteins involved in pathogen recognition and activation of immune responses. It also includes TraesCS1B02G017700and …

Extensive lesions were also observed when manipulating plant intrinsic catalase activity
Similar to what has been observed in other plant species, supplying rice leaves with G/GO resulted in the sustained production of H2O2within the apoplast , whereas a mixture of xanthine and xanthine oxidase was found to generate both superoxide and H2O2, the latter by dismutation. Treatment with either compoundor with the enzymes alone had no …
The absorbance was measured at 450 nm with a Spectramax 34C microplate reader
The average mass of CMG2-Fc per kg leaf fresh weight was 717 and 874 mg/kg leaf FW for the Kifunensine and Kifunensine samples, respectively . The control group expression level was consistent with previous results. These data suggest that the addition of kifunensine in the agro-infiltration process was not detrimental to transient protein production, and in this case, …
