S-phase, G2, and nuclear division mutants of Aspergillus nidulans.
Twenty-two temperature-sensitive cell cycle mutants of the fungus Aspergillus nidulans, which block in interphase at restrictive temperature, were analyzed by the reciprocal shift method of Jarvik and Botstein (Proc. Nath Acad. Sci. U.S.A. 70:2046-2050, 1973) and Hereford and Hartwell (J. Mol. Biol. 84:445-461, 1974) to determine whether these mutations were blocked at the G1, S, or G2 phase of...
متن کاملAsynchronous nuclear division cycles in multinucleated cells
Synchronous mitosis is common in multinucleated cells. We analyzed a unique asynchronous nuclear division cycle in a multinucleated filamentous fungus, Ashbya gossypii. Nuclear pedigree analysis and observation of GFP-labeled spindle pole bodies demonstrated that neighboring nuclei in A. gossypii cells are in different cell cycle stages despite close physical proximity. Neighboring nuclei did n...
متن کاملInduction of symmetrical nucleus division and multi-nuclear structures in isolated microspores of sugarcane (Saccharum officinarum L.)
In this study, the effects of floret sterilization with sodium hypochlorite, cold stress, heat shock, 2,4-dichlorophenoxyacetic acid and colchicine treatment on microspore viability and induction of symmetrical nuclei divisions were assessed in six genotypes of sugarcane. The highest microspore viability was observed when florets were sterilized with 3.0% and 3.5% sodium hypochlorite in all gen...
متن کاملNuclear Division: Giving Daughters Their Fair Share
How do nuclear components, apart from chromosomes, partition equally to daughter nuclei during mitosis? In Schizosaccharomyces japonicus, the conserved LEM-domain nuclear envelope protein Man1 ensures the formation of identical daughter nuclei by coupling nuclear pore complexes to the segregating chromosomes.
متن کاملDistribution of PCNA in Drosophila embryo during nuclear division cycles.
An immunocytochemical method using a specific antibody was employed to detect the proliferating cell nuclear antigen (PCNA) in Drosophila embryos during the first 13 nuclear division cycles. Strong nuclear staining with the anti-PCNA antibody was observed at interphase throughout 13 cycles. Metaphase chromosomes were not stained throughout these cycles. The chromosomal (nuclear) staining reappe...
