Co-expression network analysis for identification of candidate genes regulating phosphorus use efficiency in wheat (Triticum aestivum L.)

Phosphorus (P) is a crucial nutrient for plants, but its deficiency can significantly reduce crop yields, especially in wheat. To understand the genetic basis of Phosphorus Use Efficiency (PUE) in wheat, we analyzed the gene expression patterns of plants under phosphorus stress. We identified and analyzed 1194 differentially expressed genes, constructing a network of these genes through cytoscape. We have extracted 26 hub genes from this network, which are key players in PUE. These hub genes are involved in various biological processes related to phosphorus uptake, transport and utilization, as revealed by KEGG pathway analysis. Our findings provide valuable insights into the genetic mechanisms underlying PUE in wheat and may contribute to the development of strategies for improving crop yields in phosphorus-deficient environments.
