Many Expressed Sequence Tags (EST) sequencing projects produce thousands of sequences that must be cleaned and annotated. Here it is presented Full-Lengther, an algorithm that can find out full-length cDNA sequences from EST data. To accomplish this task, Full-Lenther is based on a BLAST report using a protein database such as UniProt. Blast alignments will guide to locate protein coding region...

For comprehensive analysis of genes expressed in the model dicotyledonous plant, Arabidopsis thaliana, expressed sequence tags (ESTs) were accumulated. Normalized and size-selected cDNA libraries were constructed from aboveground organs, flower buds, roots, green siliques and liquid-cultured seedlings, respectively, and a total of 14,026 5'-end ESTs and 39,207 3'-end ESTs were obtained. The 3'-...

BACKGROUND With the emergence of a completed genome sequence of the freshwater crustacean Daphnia pulex, construction of genomic-scale sequence databases for additional crustacean sequences are important for comparative genomics and annotation. Porcelain crabs, genus Petrolisthes, have been powerful crustacean models for environmental and evolutionary physiology with respect to thermal adaptati...

Expressed sequence tags (ESTs) are a valuable source of molecular markers. To enhance the resolution of an existing linkage map and to identify putative functional polymorphic gene loci in hexaploid wheat (Triticum aestivum L.), over 260,000 ESTs from 5 different grass species were analyzed and 5418 SSR-containing sequences were identified. Using sequence similarity analysis, 156 cross-species ...

We describe FrameD, a program that predicts coding regions in prokaryotic and matured eukaryotic sequences. Initially targeted at gene prediction in bacterial GC rich genomes, the gene model used in FrameD also allows to predict genes in the presence of frameshifts and partially undetermined sequences which makes it also very suitable for gene prediction and frameshift correction in unfinished ...

Aligning cDNA sequences to genomic sequences is a very common way to study expressed sequences, find their genes, and study alternative splicing. Several computer programs address this problem, using heuristics to define exon regions. Usually, standard alignment algorithms are not used to align ESTs to genomic DNA, due to the existence of large regions of introns. This paper compares the EST-to...

MOTIVATION High accuracy of data always governs the large-scale gene discovery projects. The data should not only be trustworthy but should be correctly annotated for various features it contains. Sequence errors are inherent in single-pass sequences such as ESTs obtained from automated sequencing. These errors further complicate the automated identification of EST-related sequencing. A tool is...

Fusarium culmorum is one of the most common and globally important causal agent of root and crown rot diseases of cereals. These diseases cause grain yield loss and reduced grain quality in barley. In this study, we have analyzed an expressed sequence tag (EST) database derived from F. culmorum infected barley root tissues available at the National Center for Biotechnology Information (NCBI). T...

detection of mycoplasma synoviae (ms) by culture and polymerase chain reaction (pcr) has been reported from commercial chicken farms in different provinces of iran. in some reports the phylogenetic analysis of ms isolates based on 16s rrna and variable lipoprotein hemagglutinin (vlha) genes have been carried out. the pcr product containing partial 16s rrna genes of iranain isolates was sequence...
