Welcome to WheatCENet!

WheatCENet (Comparing Co-expression Networks of allohexaploid Wheat and its progenitors) database integrated 425 transcriptomic datasets (112 for Triticum aestivum (AABBDD), 153 for Triticum dicoccoides (AABB), 76 for Triticum urartu (AA), 42 for Aegilops tauschii (DD) from public databases to construct four global (T. aestivum, T. dicoccoides, T. urartu, and Ae. tauschii) and two T. aestivum conditional (tissue-specific and stress-treatment) co-expression network based on the PCC and MR algorithms.
We also collected comprehensive functional annotations (for example, Gene family, Ontology, miRNA, Metabolic pathway and so on) to predict gene functions. Besides, we provided analysis tools like GSEA, GO, module and motif analysis to analyze the possible function of gene sets and some basic tools like ID conversion, BLAST, sequence/FPKM extract. We hope that our database might help plant research communities to identify wheat functional genes or modules that regulate important agronomic traits.
