Hyphal cells of Neurospora crassa (Ascomycota) growing on semi-solid agar. Bar: 0.7 mm.

Hyphal tip organization. Phase contrast light microscopy illustrating Spitzenkörper (Spk) (A, black arrow, N. crassa) and apical vesicle crescent (AVC) (B, black arrow, Rhizopus oryzae, Mucoromycota). Phase-bright core (asterisk), mitochondria (white arr

The hyphal apex. (A-F) Transmission electron microscopy (TEM) of N. crassa hyphae prepared using cryo-fixation and freeze substitution. (A) Section through hyphal apex illustrating the core of the Spk (asterisk) surrounded by macrovesicles (arrows). Ribos

The hyphal apex. (A) Wide-field epifluorescence microscopy of FM4-64 stained hyphae of Coemansia reversa (Mucoromycota). Labelled secretory vesicles making up the AVC (arrow). Other small organelles are label in subapical region of hypha. Scale bar 2 µm.

Cytoplasmic behavior in the hyphal apex. (A) Growth of N. crassa hypha viewed with phase contrast light microscopy illustrates bulk flow (i.e., moving at the same rate as the growing tip). Multiple mitochondria (M) subtend the Spk. Individual mitochondria

The microtubular cytoskeleton. (A) Confocal microscopy of immuno-labelled Mt cytoskeleton in hypha of N. crassa. Mts exhibit a helical-like organization (arrows). Regions of cytoplasm where Mts are less abundant (asterisks) represent areas occupied by nuc

The actin cytoskeleton. (A) Wide-field epifluorescence microcopy of actin after staining with rhodamine-phalloidin a hypha of R. oryzae. Actin plaques (arrows) are part ofthe cortical endocytic collar. Nuclei (asterisks) stained with DAPI. Scale bar 3 µm

Research Interests

Robby Roberson studies cell behavior and cytoplasmic order/dynamics during growth and differentiation using basic and advanced bioimaging tools. His primary interests involve cellular mechanisms that sustain and regulate polarized cell growth in fungal hyphae.
