2HA and WT (A17) plants in the presence of AVG (ethylene inhibitor) or ACC (ethylene precursor) were compared for nodulation (a and b), (c) number of short lateral roots (<5 mm) per plant and (d) number of long lateral roots (>5 mm) per plant. Bars marked with different letters differ significantly at p < 0.05 (Kruskal-Wallis test). Results are mean ± SE (n = 25).
