Abstract: | 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. |
