Abstract: | Reforestation in the humid tropics and arid zones, where trees are often subject to stresses, is an effective approach for
mitigating global warming. Forestation with Populus species that are tolerant to the stresses in such regions has been conducted. The selection of poplar trees with higher stress
tolerance leads to more efficient reforestation. The genome-wide bioinformatics approaches of gene function have been used
for revealing the mechanisms of biological processes, including such stress tolerance. The decoding of the poplar genome has
been followed by the genome-wide identification of genes and then the inference of gene function for systematic understanding
of biological processes. To predict gene function in poplar, we analyzed poplar gene expression data using DNA microarray
datasets obtained from the Gene Expression Omnibus database and developed a database for poplar gene co-expression analysis.
Using the database, we illustrate the steps to retrieve two groups of co-expressed genes that are specifically expressed in
experiments of hypoxic stress response in gray poplar, a flooding-tolerant tree species. Our database allows users to extract
genes involved in biological processes, such as stress reaction, and then is useful for understanding such mechanisms in tree
species. |
