Genomewide Expression and Functional Interactions of Genes under Drought Stress in Maize

Figure 6

Specific coexpression network of the selected 174 drought-specific DEGs from HKI1532. Every gene fell into one of the eleven clusters, each module representing one specific biological function category. Maximum coexpression in the network was shown by clusters 1, 2, and 3, of which cluster 3 showed the highest degree of coexpression with other genes of the network. Coexpression of genes from different pathways as seen in this network led to drought tolerance in HKI1532.
