Fig. 6From: Identification of candidate genes and residues for improving nitrogen use efficiency in the N-sensitive medicinal plant Panax notoginsengResponse of nitrate signal-sensing and transduction pathway-related proteins to N levels. The pathway map was prepared by using KEGG PATHWAY Database. With each box, each column is different nitrogen treatment (from left to right: N0, N7.5 and N15) as shown in the middle upper part. Average proteins intensity is color key scale according the scale in the middle upper partBack to article page
