Objective To detect and locate the single nucleotide polymorphism(SNP) in the core promoter region of NR2B gene of rats.Methods Genomic DNA from hippocami of 16 healthy SD rats was extracted.Polymerase chain reaction was used to clone the core promoter region sequence and rs8169392 region reporte...
Nucleotide sequence analysis of the region surrounding the transposition site revealed a 1,065-bp open reading frame (ORF). A homology search of the GenBank/EMBL database revealed that the amino acid sequence of this ORF had 46.8% similarity and 21.2% identity with the alpha1,2 N-...
GenBank database (accession number: NC_007089.4) was used as an outgroup for these phylogenetic analyses. Overall, the identification ofAcanthamoebaspecies was based on the two following criteria: nucleotide similarity <100% in pairwise comparisons and bootstrap threeshold <90% in phylogenetic ...

including the pathways of synthesis of small molecules, macromolecules, and cell structure components. Most (85%) of the top 33 biosynthesis pathways belonged to amino acid biosynthesis, fatty acid and lipid biosynthesis, and nucleoside and nucleotide biosynthesis. Similar pathways were reported to be...
Single nucleotide polymorphisms (SNPs) are efficient molecular markers for exploring the genetic diversity, phylogenetic relationships, and population structure of tea accessions from different regions [4, 9, 10]. For example, genome re-sequencing of 190 Camellia accessions has revealed that C. ...

We used Fisher’s combined test to obtain a combined test statistic for each gene, summarizing individual comparisons from all datasets (Supplementary Data3). Based on the elbow of theP-value-rank plot, we selected from the top 500 genes with the lowestP-value those with absolute log2fold ch...
