Fig. 5From: Transcriptional regulation mechanism of wheat varieties with different nitrogen use efficiencies in response to nitrogen deficiency stressNitrogen metabolism pathway analysis of the tested cultivars. A Nitrogen metabolism pathway in ZM366; B Nitrogen metabolism pathway in JD8; C Nitrogen metabolism pathway in hybrid cultivar. The green pattern indicating all the DEGs mapped to the step were down-regulated. The red pattern indicating all the DEGs mapped to the step were up-regulated. The blue indicating the DEGs mapped to this step were either up-regulated or down-regulated DEGsBack to article page
