From: A chemical screen identifies two novel small compounds that alter Arabidopsis thaliana pollen tube growth

Fig. 1

Dose-response effect of the compounds on Arabidopsis thaliana pollen tubes. a Structure of the compounds selected during the chemical screen and further investigated in the present study: Disruptol-A, Disruptol-B, Galvestine-1 and the negative control of galvestine-1: G0. b Dose-response effect of the compounds on pollen tube phenotype. c Effect of the selected concentration of the compounds after 6 h of culture on pollen germination, phenotype rates and pollen tube length. Data represent the mean of (665 ≤ n ≤ 1249) pollen for pollen germination and phenotype or (34 ≤ n ≤ 76 pollen tubes) for pollen tube length from two biological replicates ± SEM (Standard Error of the Mean). Asterisks indicate significant differences (*** P < 0.001, ** P < 0.01 and * P < 0.05) from the control DMSO 0.3% according to pairwise comparison using Dunnett’s test analysis with R software. Red framed Images indicate the selected concentrations. Green arrows indicate bulging pollen tubes. Blue arrows indicate misshaped pollen tubes. Orange arrows indicate shorter pollen tubes. Scale bar = 40 μm
