How a "Smart regulatory" platform can improve the property fee adjustment dilemma.

In the current process of social and economic development, the cost of living and property management is continuously increasing. In order to maintain the normal operation of property management and provide high-quality services, it is necessary to adjust the property fees reasonably. If the property fees cannot be adjusted for a long time, it will have a detrimental impact on the development of the community.

Decades of Genetic Research on Resistance in Soybean.

This review summarizes the history and current state of the known genetic basis for soybean resistance to (SMV), and examines how the integration of molecular markers has been utilized in breeding for crop improvement. SVM causes yield loss and seed quality reduction in soybean based on the SMV strain and the host genotype. Understanding the molecular underpinnings of SMV-soybean interactions and the genes conferring resistance to SMV has been a focus of intense research interest for decades.

Whole genome-wide transcript profiling to identify differentially expressed genes associated with seed field emergence in two soybean low phytate mutants.

Background: Seed germination is important to soybean (Glycine max) growth and development, ultimately affecting soybean yield. A lower seed field emergence has been the main hindrance for breeding soybeans low in phytate. Although this reduction could be overcome by additional breeding and selection, the mechanisms of seed germination in different low phytate mutants remain unknown.

Salt-Responsive Transcriptome Profiling of Suaeda glauca via RNA Sequencing.

Background: Suaeda glauca, a succulent halophyte of the Chenopodiaceae family, is widely distributed in coastal areas of China. Suaeda glauca is highly resistant to salt and alkali stresses. In the present study, the salt-responsive transcriptome of Suaeda glauca was analyzed to identify genes involved in salt tolerance and study halophilic mechanisms in this halophyte.

[Drug susceptibility and UL97 gene mutation analysis of cytomegalovirus in recipients of hematopoietic stem cell transplantation].

Objective: To monitor human cytomegalovirus (HCMV) drug resistance in recipients of hematopoietic stem cell transplantation by phenotypic and genotypic methods.

Methods: HCMV clinical isolates was isolated from the urine of hematopoietic stem cell transplantation recipients treated with GCV. Tissue cell infection median dose (TCID50) of the isolates was calculated using Reed-Muench method, and their drug susceptibility was determined by plaque reduction assay.

Natural variation underlies alterations in Nramp aluminum transporter (NRAT1) expression and function that play a key role in rice aluminum tolerance.

Aluminum (Al) toxicity is a major constraint for crop production on acid soils which compose ∼ 40% of arable land in the tropics and subtropics. Rice is the most Al-tolerant cereal crop and offers a good model for identifying Al tolerance genes and mechanisms. Here we investigated natural variation in the rice Nramp aluminum transporter (NRAT1) gene encoding a root plasma membrane Al uptake transporter previously hypothesized to underlie a unique Al tolerance mechanism.

Identification and characterization of the soybean IPK1 ortholog of a low phytic acid mutant reveals an exon-excluding splice-site mutation.

Phytic acid (myo-inositol 1, 2, 3, 4, 5, 6 hexakisphosphate) is an important constituent of soybean meal. Since phytic acid and its mineral salts (phytates) are almost indigestible for monogastrics, their abundance in grain food/feed causes nutritional and environmental problems; interest in breeding low phytic acid has therefore increased considerably. Based on gene mapping and the characteristics of inositol polyphosphates profile in the seeds of a soybean mutant line Gm-lpa-ZC-2, the soybean ortholog of inositol 1,3,4,5,6 pentakisphosphate (InsP(5)) 2-kinase (IPK1), which transforms InsP(5) into phytic acid, was first hypothesized as the candidate gene responsible for the low phytic acid alteration in Gm-lpa-ZC-2.

The reduction of reactive oxygen species formation by mitochondrial alternative respiration in tomato basal defense against TMV infection.

The role of mitochondrial alternative oxidase (AOX) and the relationship between systemic AOX induction, ROS formation, and systemic plant basal defense to Tobacco mosaic virus (TMV) were investigated in tomato plants. The results showed that TMV inoculation significantly increased the level of AOX gene transcripts, ubiquinone reduction levels, pyruvate content, and cyanide-resistant respiration (CN-resistant R) in upper, un-inoculated leaves. Pretreatment with potassium cyanide (KCN, a cytochrome pathway inhibitor) greatly increased CN-resistant R and reduced reactive oxygen species (ROS) formation, while application of salicylhydroxamic acid (SHAM, an AOX inhibitor) blocked the AOX activity and enhanced the production of ROS in the plants.

Multiplex single nucleotide polymorphism (SNP) assay for detection of soybean mosaic virus resistance genes in soybean.

Soybean mosaic virus (SMV) is one of the most destructive viral diseases in soybean (Glycine max). Three independent loci for SMV resistance have been identified in soybean germplasm. The use of genetic resistance is the most effective method of controlling this disease.

Systemic induction and role of mitochondrial alternative oxidase and nitric oxide in a compatible tomato-Tobacco mosaic virus interaction.

The role of mitochondrial alternative oxidase (AOX) and the relationship between AOX and nitric oxide (NO) in virus-induced systemic defense to Tobacco mosaic virus (TMV) were investigated in susceptible tomato (Solanum lycopersicum) plants. TMV inoculation to the lower leaves induced a rapid NO synthesis and AOX activation in upper uninoculated leaves as early as 0.5 day postinoculation.

Decreased energy synthesis is partially compensated by a switch to sucrose synthase pathway of sucrose degradation in restricted root of tomato plants.

Tomato (Solanum lycopersium L.) plants were grown hydroponically to investigate the changes of energy metabolism and adaptive mechanism in response to root restriction. Root restriction resulted in a significant increase in root lipid peroxidation and reduction in leaf net CO(2) assimilation rate, which was accompanied by increase of alcohol dehydrogenase (ADH; EC 1.

Putrescine enhancement of tolerance to root-zone hypoxia in Cucumis sativus: a role for increased nitrate reduction.

Cucumber (Cucumis sativus L.) plants were subjected to hypoxic stress with or without a pretreatment of putrescine (Put) to investigate whether nitrate reduction is involved in the enhancement effects of Put on tolerance to root-zone hypoxia. Both hypoxic stress and exogenous Put application significantly increased the contents of endogenous Put, spermidine and spermine.
