Abstract Gene duplication is a major mechanism to create new genes. After gene duplication, some duplicated genes undergo functionalization, whereas others largely maintain redundant functions. Duplicated comprise various degrees of functional diversification in plants. However, the evolutionary fate high and low diversified duplicates unclear at genomic scale. To infer Arabidopsis thaliana genome, we generated prediction method for predicting whether pair duplicate was subjected or based on...
Seasonal changes in spring induce flowering by expressing the florigen, FLOWERING LOCUS T (FT),
Heme, an organometallic tetrapyrrole, is widely engaged in oxygen transport, electron delivery, enzymatic reactions, and signal transduction. In plants, it also involved photomorphogenesis photosynthesis. HEME OXYGENASE 1 (HO1) initiates the first committed step heme catabolism, has generally been thought that this reaction takes place chloroplasts. Here, we show HO1 both Arabidopsis (Arabidopsis thaliana) rice (Oryza sativa) 2 transcription start sites (TSSs), producing long (HO1L) short...
Among human T cell leukemia virus type 1 (HTLV-1)-infected individuals, there is an association between HTLV-1 tax subgroups (subgroup-A or subgroup-B) and the risk of HAM/TSP in Japanese population. To investigate role viral pathogenesis, we studied functional difference subgroup-specific transcriptional regulators Tax HBZ using microarray analysis, reporter gene assays, evaluation viral-host protein-protein interaction.(1) Transcriptional changes Jurkat Tet-On T-cells that express each...
DNA methylation is an important factor regulating gene expression in organisms. However, whether plays a key role adaptive evolution unknown. Here, we show evidence of naturally selected Arabidopsis thaliana In comparison with single nucleotide polymorphisms, three types methylation-methylated CGs (mCGs), mCHGs, and mCHHs-contributed highly to variable levels among Athaliana population. Such variably expressed genes largely affect large variation specialized metabolic quantities. Among the...
Lineage-specific gene duplications contribute to a large variation in specialized metabolites among different plant species. There is also considerable variability the within single However, it unclear whether copy number variations (CNVs) derived from duplication events diversity of We identified metabolome quantitative trait genes (mQTGs) associated with metabolite and examined relationship between mQTGs CNVs. obtained 1,335 signals 53 worldwide A. thaliana accessions using liquid...
There is considerable diversity in the specialized metabolites within a single plant species (intra-species) and among different (inter-species). The functional divergence associated with gene duplications largely contributes to inter-species metabolites, whereas intra-species due dosage changes via [i.e., copy number variants (CNVs)] at level of evolution. This because CNVs are thought undergo less However, caused by may induce metabolite levels We herein discuss metabolic quantitative...
Radish (Raphanus sativus L. var. sativus), a widely cultivated root vegetable crop, possesses large sink organ (the root), implying that photosynthetic activity in radish can be enhanced by altering both the source and capacity of plant. However, since is self-incompatible plant, improved mutation-breeding strategies are needed for this crop. TILLING (Targeting Induced Local Lesions IN Genomes) powerful method used reverse genetics. In study, we developed new strategy involving two-step...
Natural genetic variation has facilitated the identification of genes underlying complex traits such as stress tolerances. We here evaluated long-term (L-) heat tolerance (37°C for 5 days) 174 Arabidopsis thaliana accessions and short-term (S-) (42°C, 50 min) 88 found extensive variation, respectively. Interestingly, L-heat-tolerant are not necessarily S-heat tolerant, suggesting that mechanisms different. To elucidate we performed a chromosomal mapping using F2 progeny cross between Ms-0 (a...
Excess soluble iron in acidic soil is an unfavorable environment that can reduce rice production. To better understand the tolerance mechanism and identify genetic loci associated with toxicity (FT) a highly diverse indica Thai population, genome-wide association study (GWAS) was performed using genotyping by sequencing six phenotypic data (leaf bronzing score (LBS), chlorophyll content, shoot height, root length, biomass, dry weight) under both normal FT conditions. LBS showed high negative...
Influenza A virus rapidly acquires antigenic changes and antiviral drug resistance, which limit the effectiveness of vaccines treatments, primarily owing to its high rate evolution. Virus populations formed by quasispecies can contain resistance mutations even before a selective pressure is applied. To study effects viral mutation spectrum quasispecies, high- low-fidelity variants have been isolated for several RNA viruses. Here, we report discovery RdRp variant influenza that contains...
On the standpoint of dual-wavelength spectrophotometry, each component in 156 groups two-components mixture consisting 11 kinds food colors and 2 similar was directly analyzed with ordinary spectrophotometer without chromatography. Measurement for calibration equations made 0.02N ammonium acetate solution ranging concentration these dyes from 0 to 10μg/ml.The reference wavelength (λ1) measurement (λ2) chosen were shown Table 2, difference absorptivity between λ1 λ2 also 3.

Abstract Heme, an organometallic molecule, is widely engaged in oxygen transport, electron delivery, enzymatic reactions, and signal transduction. Additionally, heme serves as a precursor to phytochromobilin, the chromophore of plant phytochrome. Heme oxygenase (HO) initiates first committed step metabolism. Our transcription start site-sequencing (TSS-seq) revealed that HO1 Arabidopsis thaliana Oryza sativa (rice) has two TSSs, producing long ( HO1L ) short HO1S transcripts, with or without...
