The hierarchy of root branching order determines bacterial composition microbial carrying capacity and microbial filtering

摘要

Root orders are colored as follows: red is R1/2 (absorptive fine roots), green is R3 (transitionary fine roots), and blue is R4/5 (transportive fine roots). For an enhanced image of R1/2 for each tree species, please see Supplementary Fig. 1. Scale bar is 50 mm.
