PacBio RS II is the first commercialized third-generation DNA sequencer able to sequence a single molecule DNA in real-time without amplification. PacBio RS II’s sequencing technology is novel and unique, enabling the direct observation of DNA synthesis by DNA polymerase. PacBio RS II confers four major advantages compared to other sequencing technologies: long read lengths, high consensus accuracy, a low degree of bias, and simultaneous capability of epigenetic characterization. These advantages surmount the obstacle of sequencing genomic regions such as high/low G+C, tandem repeat, and interspersed repeat regions. Moreover, PacBio RS II is ideal for whole genome sequencing, targeted sequencing, complex population analysis, RNA sequencing, and epigenetics characterization. With PacBio RS II, we have sequenced and analyzed the genomes of many species, from viruses to humans. Herein, we summarize and review some of our key genome sequencing projects, including full-length viral sequencing, complete bacterial genome and almost-complete plant genome assemblies, and long amplicon sequencing of a disease-associated gene region. We believe that PacBio RS II is not only an effective tool for use in the basic biological sciences but also in the medical/clinical setting. 相似文献

Effects of atrial natriuretic peptide (ANP) on renin release in isolated rat glomeruli were investigated. ANP suppressed renin release by 25% at 5 x 10(-8) M when glomeruli were incubated in a medium containing 1.26 mM calcium (p = 0.0019). When glomeruli were incubated in a calcium free medium containing 2 mM EGTA, ANP suppressed stimulated renin release significantly at 5 x 10(-8) and 5 x 10(-9) M by 25% (p = 0.0204, and p = 0.0101, respectively). These results indicate that ANP suppresses renin release in a dose dependent manner, probably through a calcium independent process. 相似文献

A new species Dendrocalamus menglongensis Hsueh & K. L. Wang ex N. H. Xia, R. S. Lin &Y. B. Guo is described and illustrated from Xishuangbanna, Yunnan, China. It differs from D. giganteus by e.g. shorter internodes, 4–5 florets, a perfect terminal floret and persistent culm sheaths. A key to the new species and the other 7 species of Dendrocalamus known from Xishuangbanna is provided. 相似文献

Quality control operates at different steps in translation to limit errors to approximately one mistranslated codon per 10,000 codons during mRNA-directed protein synthesis. Recent studies have suggested that error rates may actually vary considerably during translation under different growth conditions. Here we examined the misincorporation of Phe at Tyr codons during synthesis of a recombinant antibody produced in tyrosine-limited Chinese hamster ovary (CHO) cells. Tyr to Phe replacements were previously found to occur throughout the antibody at a rate of up to 0.7% irrespective of the identity or context of the Tyr codon translated. Despite this comparatively high mistranslation rate, no significant change in cellular viability was observed. Monitoring of Phe and Tyr levels revealed that changes in error rates correlated with changes in amino acid pools, suggesting that mischarging of tRNATyr with noncognate Phe by tyrosyl-tRNA synthetase was responsible for mistranslation. Steady-state kinetic analyses of CHO cytoplasmic tyrosyl-tRNA synthetase revealed a 25-fold lower specificity for Tyr over Phe as compared with previously characterized bacterial enzymes, consistent with the observed increase in translation error rates during tyrosine limitation. Functional comparisons of mammalian and bacterial tyrosyl-tRNA synthetase revealed key differences at residues responsible for amino acid recognition, highlighting differences in evolutionary constraints for translation quality control. 相似文献
