چکیده

EGENES is a knowledge-based database for efficient analysis of plant ESTs that was recently added to the KEGG suite of databases. It links plant genomic information with higher order functional information in a single database. It also provides gene indices for each genome. The genomic information in EGENES is a collection of EST-contigs constructed from assembly of expressed sequence tags (ESTs). Due to the extremely large genomes of plant species, the bulk collection of data such as ESTs is a quick way to capture a complete repertoire of genes expressed in an organism. Using ESTs for reconstructing metabolic pathways is a new expansion in KEGG and provides researchers with a new resource for species in which only EST sequences are available. Functional annotation in EGENES is a process of linking a set of genes/transcripts in each genome with a network of interacting molecules in the cell. EGENES is a multispecies, integrated resource consisting of genomic, chemical, and network information containing a complete set of building blocks (genes and molecules) and wiring diagrams (biological pathways) to represent cellular functions. Using EGENES, genome-based pathway annotation and EST-based annotation can now be compared and mutually validated. The ultimate goals of EGENES will be to bring new plant species into KEGG by clustering and annotating ESTs; to abstract knowledge and principles from large-scale plant EST data; and to improve computational prediction of systems of higher complexity. EGENES will be updated at least once a year. EGENES is publicly available and is accessible by following link or by KEGG's navigation system

Transcriptome and Metabolite analysis reveal candidate genes of the cardiac glycoside biosynthetic pathway from Calotropis procera

Calotropis procera is a medicinal plant of immense importance due to its pharmaceutical active components, especially cardiac glycosides (CG). As genomic resources for this plant are limited, the genes involved in CG biosynthetic pathway remain largely unknown till date. Our study on stage and tissue specific metabolite accumulation showed that CG's were maximally accumulated in stems of 3 mont...

AtIPD: a curated database of Arabidopsis isoprenoid pathway models and genes for isoprenoid network analysis.

Isoprenoid biosynthesis is one of the essential metabolic pathways in plants and other organisms. Despite the importance of isoprenoids for plant functions, not much is known about the regulation of isoprenoid synthesis. Quantitative technologies and systems approaches are now increasingly used to investigate the regulation of metabolic pathways and networks. A prerequisite for systems approach...

Transcriptome analysis of the freshwater pearl mussel, Hyriopsis cumingii (Lea) using illumina paired-end sequencing to identify genes and markers

The transcriptome of triangle sail mussel Hyriopsis cumingii (Lea) using Illumina paired-end sequencing technology was conducted and analyzed. Equal quantities of total RNA isolated from six tissues, including gonad, hepatopancreas, foot, mantel, gill and adductor muscle, were pooled to construct a cDNA library. A total of 58.09 million clean reads with 98.48 % Q20 bases were generated. Cluster...

Bioinformatics in the post-genomics era: Towards Biology of the Systems

A grand challenge in genome science of the 21 century is to computationally predict systemic functional behaviors of the cell, organism, and the ecosystem from genomics and molecular information, especially for the purpose of medical, industrial, and other practical applications. This will require new bioinformatics, not simply for screening the large-scale data, but rather for reconstructing t...
