infectious bronchitis virus (ibv) is an acute and contagious viral disease of poultry that affects different systems, including the respiratory tract in particular. ibv causes major economic losses in the poultry industry globally. due to antigenic variation of the causative agent, control of the disease is difficult. to control the disease, many vaccines that belong to different serotypes are ...

Libraries of the mammalian genome have generally been propagated in single cells and have been used for gene discovery through in vitro analyses. We have expanded upon this concept by the creation of panels of YAC transgenic mice propagating targeted megabase regions of the genome. Such a panel of mice can be called an 'in vivo library' and genes can be identified based on functional screens of...

Gene function is typically evaluated by sampling the continuum of gene expression at only a few discrete points corresponding to gene knockout or overexpression. We argue that this characterization is incomplete and present a library of engineered promoters of varying strengths obtained through mutagenesis of a constitutive promoter. A multifaceted characterization of the library, especially at...

A simple and highly efficient method was developed to produce a library of Escherichia coli clones that express a particular chromosomal gene at a wide range of expression levels. The basic strategy was to replace all or part of the upstream region of a coding sequence containing the elements involved in its expression (promoter, operator, gene coding for a regulator, ribosome binding site, and...

A bacterial artificial chromosome (BAC) library for the A-genome of cotton has been constructed from the leaves of G. arboreum L cv. Jianglinzhongmian. It is used as elite A-genome germplasm resources in the present cotton breeding program and has been used to build a genetic reference map of cotton. The BAC library consists of 123,648 clones stored in 322 384-well plates. Statistical analysis ...

Positional cloning in bread wheat is a tedious task due to its huge genome size and hexaploid character. BAC libraries represent an essential tool for positional cloning. However, wheat BAC libraries comprise more than million clones, which makes their screening very laborious. Here, we present a targeted approach based on chromosome-specific BAC libraries. Such libraries were constructed from ...

The Blue Gene/L supercomputer uses system-on-a-chip integration and a highly scalable 65,536 node cellular architecture to deliver 360 Teraflops of peak computing power. Efficient operation of the machine requires a fast, scalable and standards compliant MPI library. Researchers at IBM and Argonne National Labs are porting the MPICH2 library to Blue Gene/L . We present the current state of the ...

background: parasitic nematodes cause animal and human diseases of major socio-economic importance worldwide. the suppression of parasite development at particular developmental stages could provide an alternative approach for nema-tode control. in this study, ascaris suum was used as a model system in the study of the differentially expressed genes in the infective l3 stage. methods: the gene ...
