Temperature-Dependent Growth Defect and Lignin Accumulation in the lig Seedlings.

(A) Wild-type (Ler) and lig mutant seedlings were cultured at various temperatures for 7 d. Bar = 10 mm.

(B) Shoots and primary root tips of 5-d-old seedlings stained with phloroglucinol-HCl to detect lignin. Bars = 100 µm.
