Fig 1. pgkc-1 mutant exhibits enhanced pollen germination and growth depolarization.

Fig 1

(A) WT pollen tube morphology. (B) pgkc-1 (SALK_066422C) pollen tube morphology. (C) Complemented pgkc-1 pollen tube morphology. Scale bar = 50 μm. (D) Pollen germination rate at 3 h and 9 h, respectively. pgkc-1 germinated at higher rates than WT and complemented pollen, especially at the early time point. (E) Pollen tube length of WT, pgkc-1 mutant, and genetically complemented pgkc-1 plants at 9 h after germination. (F) Pollen tube width of WT, pgkc-1 mutant, and genetically complemented pgkc-1 plants at 9 h after germination. Bars represent mean ± SEM. Asterisks indicate significant differences (** = p < 0.001) versus WT as determined by Student’s t-test.
