Strigolactones and an ethylene precursor reduce Physcomitrella spore germination rate. (a) Ppccd8 strigolactone biosynthesis mutants (Proust et al., 2011) germinate faster than their corresponding wild‐type (WT). (b) Ppccd8 mutant germination can be inhibited by exogenously applied synthetic strigolactone GR24, which also inhibits WT spore germination. Day 5 data shown; a Kruskal–Wallis test indicates significant differences between samples, P < 0.05 as indicated by the letters on the graph. (c) The ethylene precursor 1‐aminocyclopropane‐1‐carboxylic acid (ACC) inhibits WT spore germination rate. (d) The ethylene inhibitor aminoisobutyric acid (AIB) can rescue the effects of ACC on spore germination. Error bars ± SEM.
