Abstract Seed storability largely determines the vigor of seeds during storage and is significant in agriculture ecology. However, underlying genetic basis remains unclear. In present study, we report cloning characterization rice (Oryza sativa) indole-3-acetic acid (IAA)-amido synthetase gene GRETCHEN HAGEN3-2 (OsGH3-2) associated with seed storability. OsGH3-2 was identified by performing a genome-wide association study germplasms linkage mapping chromosome substitution segment lines,...
Seed deterioration during storage poses a significant challenge to rice production, leading drastic decline in both edible quality and viability, thereby impacting overall crop yield. This study aimed address this issue by further investigating candidate genes associated with two previously identified QTLs for seed storability through genome association analysis. Among the screened genes, superoxide dismutase (SOD) OsCSD2 (Copper/zinc Superoxide Dismutase 2) OsCSD3, were selected study. The...
Metabolomic analysis coupled with advanced genetic populations represents a powerful tool which to investigate the plant metabolome. However, analyses of rice (Oryza sativa) metabolome have been conducted mainly using natural accessions or single biparental population. Here, flag leaves from three interconnected chromosome segment substitution line common recurrent background were used dissect metabolic diversity. We effectively multiple populations, constructed by introducing genomic...
Abstract Dendranthema indicum var. aromaticum plant has been widely used as herbal medicine in China, however, the material basis responsible for therapeutic benefits remains largely unclear. This study aimed to provide an optimized method extracting and characterizing phenolic compounds D . flower. Firstly, ultrasound-assisted combined with central composite circumscribed (CCC) design was applied optimize compound extraction. Ethanol-acetic acid (70%:2%, v/v) selected solvent, optimal...
Rice is one of the staple crops in world. Grain size an important determinant rice grain yield, but genetic basis remains unclear. Here, we report a set chromosome segment substitution lines (CSSL) developed background genome-sequenced indica cultivar Zhenshan 97. Genotyping CSSLs by single nucleotide polymorphism array shows that most carry only or two segments introduced from japonica Nipponbare. Using this population and high-density markers, total 43 quantitative trait loci were...
Seed storability, defined as the ability to remain alive during storage, is an important agronomic and physiological characteristic, but underlying genetic mechanism remains largely unclear. Here, we report quantitative trait loci (QTLs) analyses for seed storability using a high-density single nucleotide polymorphism linkage map in backcross recombinant inbred lines that was derived from cross of japonica cultivar, Nipponbare, indica 9311. Seven putative QTLs were identified under natural...
Seed dormancy, a quality characteristic that plays role in seed germination, seedling establishment and grain yield, is affected by multiple genes environmental factors. The genetic molecular mechanisms underlying dormancy rice remain largely unknown.Quantitative trait loci (QTLs) for were identified two different mapping populations, chromosome segment substitution line (CSSL) backcross inbred (BIL) population, both derived from the same parents Nipponbare, japonica cultivar with 9311, an...
The effect of cyadox on growth and apparent digestibility nutrients in weanling pigs was investigated. Cyadox (2-formylquinoxaline-N1,N4-dioxide cyanocetylhydrazone) is a derivative quinoxaline-1, 4-dioxide, promoting antimicrobial agent that used pig production. Seventy-five crossbred barrows were randomly assigned to three treatments with five replicates per treatment. dietary consisted an unmedicated diet (control), containing 100 mg/kg mg /kg olaquindox. body weight feed consumption the...
Two experiments were conducted to determine the additivity of apparent or true digestibility phosphorus (P) in soybean meal (SBM), peas, faba beans, corn, oats, broken rice meal, rough buckwheat, and sorghum for growing pigs.Chromic oxide (0.3%) was used as a digestion marker both experiments.Each experiment lasted 12 d, which consisted 7-d dietary adaptation period followed by 5-d fecal collection period.Experiment 1 involved 6 diets: SBM-based control diet; 4 diets with substituted SBM; an...
Grain quality is a key determinant of commercial value in rice. Efficiently improving grain quality, without compromising yield, challenge rice breeding programs. Here we report on the identification and application gene, Chalk7, which causes slender shape decreases chalkiness Three allele-specific markers for two other genes (GS3 Chalk5) were developed, used to stack desirable alleles at these loci. The effects individual or combined loci evaluated using set near-isogenic lines, each...
Transmission ratio distortion (TRD) refers to a widespread phenomenon in which one allele is transmitted by heterozygotes more frequently the progeny than opposite allele. TRD considered as mark suggesting presence of reproductive barrier. However, genetic and molecular mechanisms underlying rice remain largely unknown. In present study, population backcross inbred lines (BILs) derived from cross japonica cultivar Nipponbare (NIP) an indica variety 9311 was utilized study base TRD. A total...
Abstract Observation of UV radiation is major importance to human health and the calculation photochemical reaction rates. However, sensitivity radiometers decays because equipment aging. A correction method therefore proposed by using a decrement formula that approximately quadratic function time obtained fitting clear-sky observation data from an aged UVS-AB-T radiometer with simulated Tropospheric Ultraviolet Visible (TUV) radiative transfer model. The corrected older are verified another...
Transmission ratio distortion (TRD) denotes the observed allelic or genotypic frequency deviation from expected Mendelian segregation ratios in offspring of a heterozygote. TRD can severely hamper gene flow between and within rice species. Here, we report fine mapping characterization two loci (TRD4.1 TRD4.2) for using large F2 segregating populations, which are derived chromosome segment substitution lines, each containing particular genomic introduced japonica cultivar Nipponbare (NIP)...
In this paper, the researches on estimation of cultivgated soil organic carbon storage and its variation trend were conducted in Shayang County, a typical agricultural county Jianghan Plain China. The results showed that order density (SOCD) was paddy > moisture yellow brown soil, mean values 4.46, 3.12 2.55 kg/m2, respectively. No matter which type, content decreased gradually from surface to deep form exponential function. By analyzing processing data 2001 2018, average SOCD topsoil...
Abstract Background: Relapse and graft-versus-host disease (GVHD) are the important complications influencing mortality for patients with high-risk acute myeloid leukemia (AML) myelodysplastic syndrome (MDS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). GVHD prophylaxis based on post-transplant cyclophosphamide (PTCy) or antithymocyte globulin (ATG) is widely used in haploidentical HSCT (haplo-HSCT). We developed a modified increased-intensity conditioning regimen...
