Fig. 1From: Genome and transcriptome analysis to understand the role diversification of cytochrome P450 gene under excess nitrogen treatmentPhylogeny of the PgCYP gene superfamily. The unrooted phylogenetic tree of 187 PnCYP genes was constructed by MEGA5.0 with the Neighbor-Joining (NJ) method. Details of the CYP450 genes from Panax notoginseng are listed in Table S1Back to article page
