Antisense oligonucleotide-mediated knock-down of tobacco EXO70C2 leads to faster pollen tube growth. Tobacco pollen tubes were incubated with 50 μM of two different antisense (AS1,AS2) and corresponding sense (S1,S2) oligodeoxynucleotides specific for EXO70C2. Non-treated wild type pollen was used as control. Microscopic images and boxplot show data from a representative experiment that was repeated twice with identical trend. At least 140 cells were measured per treatment. Different letters indicate significant differences between samples (P < 0.001). Bar, 200 μm.
