Comparative root architecture of Arabidopsis and Brachypodium. (a) Typical dicotyledon allorhiz root system architecture in 10-day-old Arabidopsis plants. Arabidopsis forms only one primary root during its development, which branches out through lateral roots. (b) Typical monocotyledon homorhiz root system architecture in a 30-day-old Brachypodium plant, composed of a primary root, crown roots and lateral roots. PR, primary root; LR, lateral root; CR, crown root. Scale bars = 1 cm.
