Despite its economic importance and recent genome release, the need for molecular tools for Hevea brasiliensis is high. In the frame of a disease resistance study, EST sequences were retrieved from public database or generated by sequencing SSH libraries. Sequences were trimmed and microsatellite motifs searched using an ad hoc bioinformatic pipeline, and pairs of primers for the amplification ...

As part of an ongoing investigation into the organization and regulation of the flavonoid biosynthetic pathway, two Arabidopsis thaliana expressed sequence tag (EST) clones (153O10T7 and YAY780) with high homology to leucoanthocyanidin dioxygenase (LDOX) or flavonol synthase (FLS) were identified. EST YAY780 was sequenced and found to encode a protein 49 to 78% identical to all LDOX sequences i...

The repetitive structure of genomic DNA holds many secrets to be discovered. A systematic study of repetitive DNA on a genomic or inter-genomic scale requires extensive algorithmic support. The REPuter program described herein was designed to serve as a fundamental tool in such studies. Efficient and complete detection of various types of repeats is provided together with an evaluation of signi...

We present a computer program, termed V-SAGE (Virtual-SAGE), designed to facilitate the analysis of gene expression profiles by combining elements of SAGE (Serial Analysis of Gene Expression) with high-throughput EST analysis. The program re-iteratively correlates sequence tags adjacent to poly(A) tail sequence strings with a second or several tags located within the cDNA adjacent to the recogn...

The pacific white shrimp, Litopenaeus vannamei, is a popular species in aquaculture. Abdominal muscle accounts for 90% of shrimp flesh. Its growth and related genes, particularly the regulatory genes, is not well known. A cDNA library of shrimp juvenile abdominal muscle was established by PCR-based SMART™ cDNA technology. Library size was 5.0 × 106 pfu (plaque-forming unit) independent clones p...

The genomes of living organisms contain many elements, including genes coding for proteins. The portions of the genes expressed as mature mRNA, collectively known as the transcriptome, represent only a small part of the genome. The expressed sequence tag (EST) databases contain an increasingly large part of the transcriptome of many species. For this reason, these databases are probably the mos...

Denphal-type Dendrobium is the most popular orchid for cut flower and potted plant trade. To improve commercial traits, many novel cultivars have been produced through hybridization by breeders. However, genetic relationship of unclear, thus hindering progress breeding programs. Therefore, development molecular markers encouraged to identify different cultivars. In this study, based on transcri...

Millions of transcript sequences have become available for characterizing the transcriptome of human and mouse. Transcript databases have been extensively mined for extracting alternative splicing information within the same species; but they also represent a potentially valuable resource for the discovery of alternative splice variants in another species. In this study, we have performed analy...

Lack of genomic sequence data and the relatively high cost of tandem mass spectrometry have hampered proteomic investigations into helminths, such as resolving the mechanism underpinning globally reported anthelmintic resistance. Whilst detailed mechanisms of resistance remain unknown for the majority of drug-parasite interactions, gene mutations and changes in gene and protein expression are p...

Mosquito-borne diseases, including dengue, malaria, and lymphatic filariasis, exact a devastating toll on global health and economics, killing or debilitating millions every year (54). Mosquito innate immune responses are at the forefront of concerted research efforts aimed at defining potential target genes that could be manipulated to engineer pathogen resistance in vector populations. We aim...
