GEDG: gene expression database of grape.

BACKGROUND

Grapes are one of the oldest cultivated fruit species in the world, known for their high nutritional value. Grapes and grape products, including wine, are significant to many economies worldwide. Both abiotic and biotic stresses significantly impact the growth and reproduction of grapevines. RNA-Seq is a key tool for studying gene expression patterns under various conditions, such as stress responses, growth and developmental stages. In order to optimise the utilisation of these data for comprehensive research and analysis, and to enhance accessibility for users, we have developed a comprehensive database that provides gene expression profiles and traits in grapes.

DESCRIPTION

We have developed the gene expression database for grapes (GEDG), an online resource that encompasses data on 9 types of abiotic (including heat, cold, hormones, light, climate, nitrogen, frozen) and biotic (disease and pests) stresses and different developmental stages. A total of 32 datasets were related to stress, 20 to growth and development, and one to chromosomal ploidy. The primary objective of GEDG is to expand and utilize transcriptome data to better understand stress responses in grapes. GEDG is the comprehensive database to integrate transcriptome and traits on grape.

CONCLUSION

The Gene Expression Database of Grape (GEDG) was created to serve as a free resource platform for researchers, offering a comprehensive collection of genetic expression profiles for grape varieties based on RNA-seq data. The database is available at https://www.gedg-vitis.cn/index.html .
