Fig 1. Effects of bacterial strains on Arabidopsis root architecture.
a-c) supervised model based clustering performed on the variables a) length b) diameter and c) area of the roots. d) Arabidopsis plantlet phenotypes (after two weeks of growing) grouped in different clusters obtained from “model based cluster” analysis in comparison with non-inoculated (control) and 50nM IAA-treated seedlings. Scale bars: 1 cm.
