The aim of this study is to compare complete genomes to identify preserved large DNA fragments in order to analyse evolution process. For this purpose, we propose an efficient method to identify conserved regions between multiple genomes. We first transform each complete genome into a permutation of Maximal Unique Matches (MUMs). Secondly, we compute the longest common sequence of MUMs in the s...

Recent development of deep sequencing technologies has facilitated de novo genome sequencing projects, now conducted even by individual laboratories. However, this will yield more and more genome sequences that are not well assembled, and will hinder thorough annotation when no closely related reference genome is available. One of the challenging issues is the identification of protein-coding s...

Bluetongue virus (BTV), the type species of the genus Orbivirus within the family Reoviridae, has a genome consisting of 10 linear double-stranded RNA genome segments. Current reverse genetics approaches for engineering the BTV genome rely upon in vitro synthesis of capped RNA transcripts from cloned cDNA corresponding to viral genome segments. In an effort to expand the utility of BTV reverse ...

MOTIVATION Array comparative genomic hybridization (CGH) allows detection and mapping of copy number of DNA segments. A challenge is to make inferences about the copy number structure of the genome. Several statistical methods have been proposed to determine genomic segments with different copy number levels. However, to date, no comprehensive comparison of various characteristics of these meth...

In this study, an efficient Agrobacterium-mediated transformation method was developed forpomegranate (Punica granatum L.), a difficult-to-transform plant. In vitro shoot segments wereinoculated with Agrobacterium tumefaciens strain LBA4404 harboring the binary vectorpBI121 carrying the neomycin phosphotransferase (nptII) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter....

A novel bluetongue virus (BTV) termed Toggenburg orbivirus (TOV) was detected in goats from Switzerland by using real-time reverse transcription-PCR. cDNA corresponding to the complete sequence of 7 of 10 double-stranded RNA segments of the viral genome was amplified by PCR and cloned into a plasmid vector. Five clones for each genome segment were sequenced to determine a consensus sequence. BL...

Amphibian genomes differ greatly in DNA content and chromosome size, morphology, and number. Investigations of this diversity are needed to identify mechanisms that have shaped the evolution of vertebrate genomes. We used comparative mapping to investigate the organization of genes in the Mexican axolotl (Ambystoma mexicanum), a species that presents relatively few chromosomes (n = 14) and a gi...
