Coexpression Module Discovery Based on Gene Expression Data

摘要：

The expressed genes of plant are often co-occurred.It is posed to biologist how to find a set of coexpressed genes that are relevant to a biological process.In this paper,we proposed a novel method to construct coexpression network.Our scheme is divided into two stages.Firstly,the different expression genes are identified by using feature selection methods.Secondly,the coexpression network is constructed based on the genes identified by the first stage.Based on real gene expression data of Arabidopsis responding to abiotic stresses,experimental results show that our method can discover the coexpression modules associated with the special biological process.
