Membranous aggregations associated with nuclei inAspergillus flavus hyphae

Protoplasma Aims and scope Submit manuscript

Summary

Different growth regions of young vegetative hyphae ofAspergillus flavus manifested structural modification of certain organelles, especially nuclei. In the apical and subapical zones the interphase nuclei had a normal, non-modified structure. In the region which was a few millimeters distant from the hyphal tip, besides normal nuclei there were some with altered morphology.

Such an altered nucleus had electron lucent nuclear content and a membranous aggregate stacked against the nuclear membrane. The aggregate was made of flat, parallel membranes of smooth endoplasmic reticulum (ER). The membranous aggregate was also found in-between two nuclei and the stacking of membranes was highly orderly.
