Figure 2. SA Suppresses Pollen Tube Growth Independent of Canonical SA Receptors.

Figure 2.

(A) The length of pollen tubes growing on pollen germination media with different pH.

(B) The length of wild-type or LAT52::NahG pollen tubes treated with 0 µM or 20 µM SA for 3 h. SA-induced inhibition of pollen tube growth is suppressed by SA hydroxylase NahG.

(C) Pollen tube length of different SA receptor and signaling mutants treated with 0 µM or 20 µM SA. The results show that npr1–2, npr3–1, npr4–3, and npr3–1 npr4–3 responded to SA in the same manner as wild-type.

Tukey’s test was used in (A) and two-way ANOVA with Tukey’s test in (B and C). A, C represent comparison from different genotypes with 0 µM SA treatment, and a, c comparison from different genotypes with 20 µM SA treatment. Error bars show ±SEM; n > 100. **p < 0.01. ND, no significant difference.
