Fig. 3From: Integrative effects of phytohormones in the phenolic acids production in Salvia verticillata L. under multi-walled carbon nanotubes and methyl jasmonate elicitationChanges in the PAL, TAT, and RAS relative expression levels of the S. verticillata leaves after elicitation with MWCNTs and MJ. PAL: phenylalanine ammonia-lyase, TAT: tyrosine aminotransferase, RAS: rosmarinic acid synthase. Bars not sharing the same superscript letter(s) are significantly different at P < 0.05 within each treatment group based on Duncan’s multiple range test. All data are means of three replicates, with error bars indicating SEBack to article page
