One segment of the assembly line used for phagosome membrane growth in P. caudatum. Cytopharyngeal ribbons bring discoidal vesicles to the left lip of the cytopharynx where the vesicles bind and then ...

Accumulations of acidosome-like vesicles are sometimes found (in this case in a predividing cell) and in this micrograph provide further evidence for invaginations of the outer membranes. It appears t...

The collapsed cytopharyngeal membrane extends from the open cytopharynx into the cytosol. This membrane is associated with many docked acidosomes, vesicles that contain V-type proton translocating ATP...

Phagocyte and budded yeast. Amoebae (D. discoideum) were plated with yeast (S. cerevisiae) in a glass bottom chamber and viewed by confocal microscopy. Fluorescence is superimposed on grey scale brigh...

The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

Localization on the cell surface of Alexa Fluor-488-α factor (left, green in merge) and Sla1-RFP (center; red in merge). Within each white box, α-factor spots first appear and are subsequently joine...

The left edge of the cytopharynx is bordered by a complex architecture designed to transport a pool of flattened vesicles to this edge where they will fuse with the cytopharyngeal membrane to expand t...

Localization of Alexa Fluor-594-α-factor-labeled endosomes (center; red in merge) and Abp140-3GFP (left; green in merge) in bni1-12 bnr1Δ cell. Abp140p binds F-actin and localizes to actin patches ...
