Fig. 1From: Metagenomics insights into responses of rhizobacteria and their alleviation role in licorice allelopathyLicorice seedling phenotypes and the expression profiles of major secondary metabolite synthesis genes in root under exogenous glycyrrhizin addition. a Licorice seedling performance; b violin plots of licorice seedling chlorophyll contents, shoot and root fresh weights; c bar plots of expression levels of major secondary metabolite synthesis genes in licorice root among different sampling stages and treatments. I, initial sampling stage; M, middle sampling stage; F, final sampling stage; A, allelochemical treatment; W, water treatment; N, no treatment in initial samples. Different letters indicate significant differences (P < 0.05; one-way ANOVA, Tukey’s HSD test)Back to article page
