The bige1 Mutant Has Increased Seminal Root Number in Seedlings.

(A) Primary roots (blue arrow) and seminal adventitious roots (green arrow) of 5-d-old wild-type (left) and bige1-umu1 (right) seedlings (right). An emerging adventitious root initial is visible at the first node (white arrows) of the mutant seedling (right) but not in the wild-type seedling (left).

(B) Histogram showing the distribution of seminal root numbers observed in 5-d-old seedlings of the wild type and mutant (n = 21).
