Oligomycin treatment inhibited pollen tube growth in a manner distinct from the pgkc-1 mutant phenotype.
(A) WT pollen tubes subjected to mock treatment. (B) WT pollen tubes treated with 40 nM oligomycin. Scale bar = 50μm. (C) Average length of 50 pollen tubes. (D) Average width of 50 pollen tubes. Bars represent mean ± SEM. Asterisks indicate significant differences versus mock treatment group as determined using Student’s t-test (* = p < 0.05).
