Rice miR1432 Fine-Tunes the Balance of Yield and Blast Disease Resistance via Different Modules.

microRNAs act as fine-tuners in the regulation of plant growth and resistance against biotic and abiotic stress. Here we demonstrate that rice miR1432 fine-tunes yield and blast disease resistance via different modules. Overexpression of miR1432 leads to compromised resistance and decreased yield, whereas blocking miR1432 using a target mimic of miR1432 results in enhanced resistance and yield.

Osa-miR162a fine-tunes rice resistance to Magnaporthe oryzae and Yield.

MicroRNAs (miRNAs) play essential roles in rice immunity against Magnaporthe oryzae, the causative agent of rice blast disease. Here we demonstrate that Osa-miR162a fine-tunes rice immunity against M. oryzae and yield traits.

Expressing a Target Mimic of miR156fhl-3p Enhances Rice Blast Disease Resistance Without Yield Penalty by Improving Expression.

MicroRNAs (miRNAs) play essential roles in the regulation of plant growth and defense responses. More and more, miRNA-3ps are reported to act in plant development and immunity. miR156 is a conserved miRNA, and most previous studies focus on its roles in plant growth, development, and yield determinacy.

Osa-miR1873 fine-tunes rice immunity against Magnaporthe oryzae and yield traits.

MicroRNAs (miRNAs) are known to fine-tune growth, development, and stress-induced responses. Osa-miR1873 is a rice-specific miRNA targeting LOC_Os05g01790. Here, we show that Osa-miR1873 fine-tunes rice immunity against Magnaporthe oryzae and yield traits via LOC_Os05g01790.

Osa-miR398b boosts H O production and rice blast disease-resistance via multiple superoxide dismutases.

miRNAs contribute to plant resistance against pathogens. Previously, we found that the function of miR398b in immunity in rice differs from that in Arabidopsis. However, the underlying mechanisms are unclear.

[Wetting agent dosage screening for traditional Chinese medicine pellet based on torque rheological property].

With lubricant and bonding effect simultaneously, wetting agent has direct effect on properties of wet mass and extrudate, thus affecting the forming quality of pellets in extrusion-spheronization process. In this research, 25 representative kinds of traditional Chinese medicine(TCM) were selected as model drugs and 20%, 30% and 40% drug loading were set with MCC as their balling agent. The torque rheological curves were measured to get parameters such as maximum torque (Tmax) and corresponding water addition (WTmax) for these 75 raw materials by a mixer torque rheometer (MTR).

[Differences in nitrogen utilization characteristics of different peanut genotypes in high fertility soils].

A total of twenty genotypes of peanut (Arachis hypogaea) were used to investigate the differences in nitrogen (N) utilization characteristics in a pot experiment with N isotope tracing analysis. Results showed the main N sources for peanut in high fertility soils following as soil N source > N fixed by root nodule source > fertilizer N source. The N uptake and accumulation in peanut from total N and the three N supplied sources (fertilizer N, soil N and N fixation) varied among the different genotypes.

An annular photobioreactor with ion-exchange-membrane for non-touch microalgae cultivation with wastewater.

To eliminate the negative impacts of pollutants in wastewater (such as suspended solids, excess N, P, heavy metals) on microalgae growth, an annular ion-exchange-membrane photobioreactor (IEM-PBR) was proposed in this study. The IEM-PBR could avoid direct mixing of algae cells with wastewater by separating them into two chambers. In the IEM-PBR, the nutrients (mainly N and P) in wastewater continuously permeated into microalgae cultures through the ion-exchange-membrane for microalgae growth, while the pollutants hardly permeated into microalgae cultures.

Direct synthesis of solvent-free multiwall carbon nanotubes/silica nonionic nanofluid hybrid material.

The solvent-free nonionic nanofluid hybrid material consisting of multiwall carbon nanotubes (MWNTs) and silica nanoparticles is prepared by a facile route. The content of MWNTs/silica nanoparticles is up to 31 wt %. The hybrid material exhibits liquid-like behavior in the absence of solvent at 45 degrees C, which is a wax solid at room temperature.

[Effects of omapatrilat on endothelin-1-induced proliferation and synthesis of cardiac fibroblasts].

Aim: To investigate the effects of omapatrilat (OMA) on endothelin-1-induced proliferation of cardiac fibroblasts (CFs).

Methods: Isolated and cultured CFs from neonatal Sprague-Dawley rats (SD) were randomly divided into 7 groups: (1) Control, (2) ET-1, (3) OMA, (4) ET-1 + OMA 10(-9) mol/L, (5) ET-1 + OMA 10(-8) mol/L, (6) ET-1 + OMA 10(-7) mol/L and (7) ET-1 + OMA 10(-6) mol/L. CFs were counted by MTT assay.

[Study on relationship between bent angles of dental fiber reinforced composites posts and their flexural properties].

Objective: To develop a new type of fiber reinforced composites (FRC) posts with optimal bent angles.

Methods: Three kinds of experimental bent posts were made with bent angle of 5 degrees, 10 degrees, and 15 degrees respectively. The flexural strength of all FRC posts was tested with a 3-point bending test.
