Brefeldin A, wortmannin, and jasplakinolide affect
motility and morphology of endosomes
To test if endosomal movements were influenced by
inhibitors of membrane trafficking through endomembrane compartments, we applied brefeldin A(BFA) and
wortmannin to root hairs ofM. truncatula. The effect of
BFAwas traceable after 10 min (Fig. 8a) in the form of
an enlargement of FYVE-labeled endosomes which
concomitantly slowed down their motility. After
60 min of exposure to 100mM BFA, we scored
significant inhibition of endosomal motility and the size
of endosomes enlarged dramatically (Fig. 8b). Two
hours of BFAtreatment resulted in large agglomerates
of aggregated endosomes (Fig. 8c, arrows), known as
the ‘BFAcompartments’ in plant cells, with a greatly
reduced motility. Exposure of hairs to 10mM wortmannin produced similar, although less prominent, effects
on FYVE-labeled endosomes (Fig. 8d–f; Movies 18–21
for BFAand Movie 22 and 23 for wortmannin).
