Click one of the following to view a real-time
video clip of vesicle motility in the subapical cytoplasm of A. macrogynus. The focal plane
in this clip is just beneath the plasma membrane and the hyphal tip is toward the top. Note that
the vesicles commonly travel alongside mitochondria. (From McDaniel & Roberson, Fungal Genetics
and Biology, in review)

of a mitochondrion moving into the mass of mitochondria subtending the Spitzenkorper.
This clip (67 KB) of a
rotating hyphal cell was constructed from data aquired through laser scanning confocal microscopy.
The green structures are microtubules which were labeled with an antibody to alpha-tubulin .
The yellow spots are areas of colocalization of both alpha and gamma tubulin (a protein found
in microtubule organizing centers), and the blue objects are nuclei.

and vesicles being transported along them.
