Phenotypes of field-grown wild-type and ltn1 mutant plants. A and B, Growth performance of whole plants (A) and leaf tip necrosis of ltn1 mutant and wild-type (WT) plants (B) grown in the field for 3 months. Bars = 20 cm in A and 1 cm in B. C to F, Agronomic traits (plant height, tiller number, 1,000-seed weight, and fertility) of wild-type (black bars) and ltn1 mutant (gray bars) plants. Error bars indicate sd (n = 15). Asterisks indicate the significance of differences between wild-type and ltn1 mutant plants as determined by Student’s t test analysis: * 0.01 ≤ P < 0.05, ** P < 0.01.
