Figure 8

Low-K+ tolerance of the cbl2 cbl3 double mutant. (A) Seedlings were grown on vertical MS plates with complete nutrients for 5 days and then transferred onto K+-deficient media (modified MS with 50, 100 or 200 μM K+) or MS medium for 10 more days before taking the photographs. (B) Measurements of seedling fresh weight under various K+-deficient conditions. (C) Total chlorophyll content of wild-type (Col-0) and cbl2 cbl3 double mutant under various K+-deficient conditions. The total chlorophyll content was expressed as mg/g shoot fresh weight. (D) Measurements of primary root length under various K+-deficient conditions. Three independent experiments were performed and data represent mean ± SE (n=3). Asterisks indicate statistically significant difference between wild-type (Col-0) and the cbl2 cbl3 mutant (Student's t-test, *P < 0.05).
