(A) Clonal UCB-1 trees, transitioned out of tissue culture eight weeks prior to inoculation with Rhodococcus isolates 1 and 2. Four treatments were performed with 16 plants per treatment for each trial. The control plants were mock-inoculated with buffer. Three inoculated treatments included bacterial suspensions of Rhodococcus isolate 1, Rhodococcus isolate 2, and both Rhodococcus isolate 1 and isolate 2. Growth curves showing height of UCB-1 plants at multiple time points after inoculation. Error bars are standard error (n = 16). (B) Seedling UCB-1 trees inoculated with Rhodococcus.
