FIGURE 3.

Percent of WT (empty bars) and E151 (solid bars) roots colonized by R. irregularis, as determined by assessing percentages of intraradicular hyphae (A,B), arbuscules (C,D), and vesicles (E,F) observed at 15 (A,C,E) and 20 (B,D,F) DAI. These data (mean ± SE; n = 5 or 6) are the result of one replicate and are the best representative of three replicates; they were subjected to Student’s t-test to determine significant differences between pea lines. An asterisk indicates significance at a 95% confidence level.
