چکیده تنش خشکی مانع از تظاهر کامل پتانسیل ژنتیکی گیاهان زراعی می شود و از این رو موجب کاهش تولیدات کشاورزی می گردد. کمبود آب می تواند باعث القای ژن ها و تغییر الگوی بیان ژن در گیاه گردد. روش آنالیز expressed sequence tag (est) راهی سریع و منطقی برای کاندید کردن ژن های جدید برای مقاومت به تنش ها می باشد. در این تحقیق تعداد 12 کتابخانه est شاهد و تنش خشکی گندم و خویشاوندان وحشی آن شامل 37138 توا...
Zea mays DataBase (ZmDB) seeks to provide a comprehensive view of maize (corn) genetics by linking genomic sequence data with gene expression analysis and phenotypes of mutant plants. ZmDB originated in 1999 as the Web portal for a large project of maize gene discovery, sequencing and phenotypic analysis using a transposon tagging strategy and expressed sequence tag (EST) sequencing. Recently, ...
The generation of large numbers of partial cDNA sequences, or expressed sequence tags (ESTs), has provided a method with which to sample a large number of genes from an organism. More than 25,000 Arabidopsis thaliana ESTs have been deposited in public databases, producing the largest collection of ESTs for any plant species. We describe here the application of a method of reducing redundancy an...
Support vector machines for separation of mixed plant-pathogen EST collections based on codon usage.
MOTIVATION Discovery of host and pathogen genes expressed at the plant-pathogen interface often requires the construction of mixed libraries that contain sequences from both genomes. Sequence identification requires high-throughput and reliable classification of genome origin. When using single-pass cDNA sequences difficulties arise from the short sequence length, the lack of sufficient taxonom...
BACKGROUND Neurocysticercosis is a disease caused by the oral ingestion of eggs from the human parasitic worm Taenia solium. Although drugs are available they are controversial because of the side effects and poor efficiency. An expressed sequence tag (EST) library is a method used to describe the gene expression profile and sequence of mRNA from a specific organism and stage. Such information ...
Whereas the verification of non-safety-related, embedded software typically focuses on demonstrating that the implementation fulfills its functional requirements, this is not sufficient for safety-relevant systems. In this case, the control software must also meet application-specific safety requirements. Safety requirements typically arise from the application of hazard and/or safety analysis ...
This paper describes the UIcluster software tool, which partitions expressed sequence tag (EST) sequences and other genetic sequences into “clusters” based on sequence similarity. Ideally, each cluster will contain sequences that all represent the same gene. UIcluster has been developed over the course of 4 years to solve this problem efficiently and accurately for large data sets consisting of...
In the absence of whole genome sequences for many organisms, the use of expressed sequence tags (EST) offers an affordable approach for researchers conducting phylogenetic analyses to gain insight about the evolutionary history of organisms. Reliable alignments for phylogenomic analyses are based on orthologous gene sequences from different taxa. So far, researchers have not sufficiently tackle...
White clover (Trifolium repens L.) is an allotetraploid species (2n = 4X = 32) that is widely distributed in temperate regions and cultivated as a forage legume. In this study, we developed expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers, constructed linkage maps, and performed comparative mapping with other legume species. A total of 7982 ESTs that could be assembled ...
