The Silkworm Knowledgebase (SilkDB) is a webbased repository for the curation, integration and study of silkworm genetic and genomic data. With the recent accomplishment of a 6X draft genome sequence of the domestic silkworm (Bombyx mori), SilkDB provides an integrated representation of the large-scale, genome-wide sequence assembly, cDNAs, clusters of expressed sequence tags (ESTs), transposable elements (TEs), mutants, single nucleotide polymorphisms (SNPs) and functional annotations of genes with assignments to InterPro domains and Gene Ontology (GO) terms. SilkDB also hosts a set of ESTs from Bombyx mandarina, a wild progenitor of B.mori, and a collection of genes from other Lepidoptera.Comparative analysis results between the domestic and wild silkworm, between B.mori and other Lepidoptera, and between B.mori and the two sequenced insects, fruitfly and mosquito, are displayed by using B.mori genome sequence as a reference framework. Designed as a basic platform, SilkDB strives to provide a comprehensive knowledgebase about the silkworm and present the silkworm genome and related information in systematic and graphical ways for the convenience of in-depth comparative studies. SilkDB is publicly accessible at http://silkworm.genomics.org.cn.

Rice is a major food staple for the world's population and serves as a model species in cereal genome research. The Beijing Genomics Institute (BGI) has long been devoting itself to sequencing, information analysis and biological research of the rice and other crop genomes. In order to facilitate the application of the rice genomic information and to provide a foundation for functional and evolutionary studies of other important cereal crops, we implemented our Rice Information System (BGIRIS), the most up-to-date integrated information resource as well as a workbench for comparative genomic analysis. In addition to comprehensive data from Oryza sativa L. ssp. indica sequenced by BGI, BGI-RIS also hosts carefully curated genome information from Oryza sativa L. ssp. japonica and EST sequences available from other cereal crops. In this resource, sequence contigs of indica (93-11) have been further assembled into Mbp-sized scaffolds and anchored onto the rice chromosomes referenced to physical/genetic markers, cDNAs and BAC-end sequences. We have annotated the rice genomes for gene content, repetitive elements, gene duplications (tandem and segmental) and single nucleotide polymorphisms between rice subspecies. Designed as a basic platform, BGI-RIS presents the sequenced genomes and related information in systematic and graphical ways for the convenience of in-depth comparative studies (http://rise.genomics.org.cn/).

【期刊论文】The Steady-state Sinusoidal Dynamic Behaviour of Peach and Pear
王俊, J. Wang; Q.J. Lu
Biosystems Engineering (2004) 87(4), 463-469,-0001,():

Foods are frequently subjected to dynamic loading during harvesting, handling, transportation, and processing. Accurate prediction of dynamic responses of foods under these loading conditions requires better understanding of their dynamic visco-elastic properties. In this article, dynamic equilibrium was determined according to sinusoidal stress-strain. When a visco-elastic specimen is subjected to a sinusoidal varying stress, the resulting strain will be a sinusoidal response of the same frequency as the stress, out of phase by a lag angle. Experiments were conducted to measure the complex modulus of intact Daguanshan peaches and Luyu pears, the phase angle by which the strain lags the stress, and their relationship with initial pre-loading and vibration input power over a range of frequencies. Both the complex modulus and the phase angle increased as the frequency increased from 20 to 200Hz. Initial pre-loading had a significant effect on the complex modulus, but not on the phase angle. Vibration input power had no significant effect on the complex modulus and phase angle. The phase angle depends not only on internal friction but also on the inertia of intact fruit.

【期刊论文】Finishing the euchromatic sequence of the human genome
王俊

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers, 99% of the euchromatic genome and is accurate to an error rate of, 1event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead.
