Article: Draft Genome Sequence of Bacillus pumilus BA06, a Producer of Alkaline Serine Protease with Leather-Dehairing Function.
[show abstract] [hide abstract]
ABSTRACT: Bacillus pumilus BA06 was isolated from the proteinaceous soil and produced an extracellular alkaline protease with leather-dehairing function. The genome of BA06 was sequenced. The comparative genome analysis indicated that strain BA06 is different in genome from the other B. pumilus strains, with limited insertions, deletions, and rearrangements.Journal of bacteriology 12/2012; 194(23):6668-9. · 3.94 Impact Factor -
Article: [Construction of a yeast two-hybrid cDNA library from the human testis].
[show abstract] [hide abstract]
ABSTRACT: To construct a human testis cDNA library for yeast two-hybrid screening. Human normal testis mRNA was purified from total RNA, and ds cDNA was synthesized and amplified using primers SMART III and CDS III oligo (dT) as the base of recombination. The purified PCR products and linearized plasmid pGADT7-Rec were co-transformed into the competent yeast Y187 and recombined by yeast homologous recombinase in the yeast cells to form an active cyclic plasmid. All the clones growing on the SD/-Leu plates were harvested to constitute a human testis cDNA library. We constructed a human testis cDNA library with high multiplication and adequate capacity, from which 2.0 x 10(6) recombinants were obtained. The amplified PCR fragments were between 0.3 kb and 4.0 kb in length. The yeast two-hybrid cDNA library of human testis was successfully constructed by the Clontech SMART method, which has prepared a ground for further studies on the molecular mechanism of spermatogenesis.Zhonghua nan ke xue = National journal of andrology 04/2012; 18(4):310-3. -
Article: Digital gene expression analysis based on integrated de novo transcriptome assembly of sweet potato [Ipomoea batatas (L.) Lam].
[show abstract] [hide abstract]
ABSTRACT: Sweet potato (Ipomoea batatas L. [Lam.]) ranks among the top six most important food crops in the world. It is widely grown throughout the world with high and stable yield, strong adaptability, rich nutrient content, and multiple uses. However, little is known about the molecular biology of this important non-model organism due to lack of genomic resources. Hence, studies based on high-throughput sequencing technologies are needed to get a comprehensive and integrated genomic resource and better understanding of gene expression patterns in different tissues and at various developmental stages. Illumina paired-end (PE) RNA-Sequencing was performed, and generated 48.7 million of 75 bp PE reads. These reads were de novo assembled into 128,052 transcripts (≥ 100 bp), which correspond to 41.1 million base pairs, by using a combined assembly strategy. Transcripts were annotated by Blast2GO and 51,763 transcripts got BLASTX hits, in which 39,677 transcripts have GO terms and 14,117 have ECs that are associated with 147 KEGG pathways. Furthermore, transcriptome differences of seven tissues were analyzed by using Illumina digital gene expression (DGE) tag profiling and numerous differentially and specifically expressed transcripts were identified. Moreover, the expression characteristics of genes involved in viral genomes, starch metabolism and potential stress tolerance and insect resistance were also identified. The combined de novo transcriptome assembly strategy can be applied to other organisms whose reference genomes are not available. The data provided here represent the most comprehensive and integrated genomic resources for cloning and identifying genes of interest in sweet potato. Characterization of sweet potato transcriptome provides an effective tool for better understanding the molecular mechanisms of cellular processes including development of leaves and storage roots, tissue-specific gene expression, potential biotic and abiotic stress response in sweet potato.PLoS ONE 01/2012; 7(4):e36234. · 4.09 Impact Factor
