GEPSdb: The Gene Expression Database of Poplar under Stress

Abstract

As a model tree species, poplar (Populus L.) has important economic and ecological value. Here, we constructed the GEPSdb (Gene Expression Database of Poplar under Stress; http://gepsdb.ahau-edu.cn/), which is an integrated database of poplar gene expression profiles derived from RNA‐seq and microarray library data. This database provides a comprehensive collection of gene expression data from poplar exposed to 14 types of environmental stress from 11 high‐quality RNA‐seq experiments and 51 microarray libraries. The GEPSdb includes 56 genes from previous literature that have been examined in poplar and functionally verified. By incorporating data from numerous expression analyses, GEPSdb provides a user‐friendly web interface for querying, browsing, and visualizing the expression profiles of related genes. Consequently, GEPSdb can be used to link transcription data with phenotypes and can enhance our understanding of important biological processes and mechanisms underlying complex agronomic traits in poplar.

Genome-Wide Identification and Characterization of Auxin Response Factor (ARF) Gene Family Involved in Wood Formation and Response to Exogenous Hormone Treatment in Populus trichocarpa

“…This kind of problem has been also demonstrated by the research on the R2R3-MYB gene family [36]. In addition, as exponentially increasing amounts of RNA-Seq data for the poplar are available [37], it is greatly helpful to update and enrich the knowledge of the PtrARF gene family at the whole-genome level.…”
