cDNA containing the 3' part sequences of seven Lily symptomless virus (LSV) isolates were obtained by RT-PCR and sequenced. The sequenced region is corresponding to partial CP gene and the entire sequences of 16kDa gene located at the 3' end of LSV genome. The sequence homologies of partial CP and 16 kDa protein genes, compared with other reported isolates, were 87.4% to 100% and 97.9% to 100% respectively...
Pear is a commercially important fruit tree widely distributed in China that displays GSI (gametophytic self-incompatibility). It is necessary to determine S-alleles and S-genotypes for clarifying the compatibility between cultivars prior to pear planting and breeding. The S-genotype analysis using conventional method of artificial pollination is time consuming and requires much labor. In addition,...
We present a global clustering approach to identify putative intergenic non-coding RNAs based on the RNA polymerase II and Histone 3 lysine 4 trimethylation signatures. Both of these signatures are processed from the digital sequencing tags produced by chromatin immunoprecipitation, a high-throughput massively parallel sequencing (ChIP-Seq) technology. Our method compares favorably to the comparison...
Computational ribonucleomics of heavy metal stress tolerant Bacillus sp. strain SJ-101 16SrRNA gene has led to the identification of a novel small non-coding RNA (sRNA) and promoter-like sequences within 3' region of the gene. Using RNAz web server, a 123 bp long functional sRNA with significant thermodynamic stability (Energy contribution: -25.2) and evolutionary conservation (structure conservation...
The pattern of genome transcription in prokaryotes is determined by selective distribution of RNA polymerase within the genome. The gene selectivity of RNA polymerase is modulated after interaction with DNA-binding transcription factors (TFs). Escherichia coli contains a total of about 300 TFs, but the regulatory function has not yet been identified for about one third. For quick and systematic search...
With the advancement of biological techniques, researches in the fields of marine evolution, ecology, and aquaculture have an explosive increasing rate both in volume and diversity. More than tens of thousands of genomic sequences were available for important marine species. However, most of the structures and corresponding functions remain unresolved and unknown. To discover the biological characteristics...
