Figure 2From: Arbuscular mycorrhizal symbiosis elicits shoot proteome changes that are modified during cadmium stress alleviation in Medicago truncatulaImpact of cadmium (Cd) and/or G. irregulare inoculation (Gi) on shoot biomass allocation patterns of 3-wk old M. truncatula plants relative to those non-treated (C), as measured by the ratio of shoot biomass (g fresh weight) to that of whole plant (A), shoot branch number per plant (B), and total leaf area (cm2) per plant (C). For two independent biological experiments (Exp), histograms represent means of three replicates (means ± SD, n = 3). Means marked with different letters indicate significant difference at p < 0.05.Back to article page
