Báo, Sônia Nair; Kitajima, Elliot Watanabe; Callaini, Giuliano; Dallai, RomanoEspermatozoides de insetos têm atraído a atenção intensiva dos citologistas, especialmente aqueles que tentam relacionar a grande diversidade de sua estrutura e do processo evolutivo. Este estudo mostra a diferenciação de células germinativas masculinas e estrutura em moscas-brancas.
A requirement for the abnormal spindle protein to organise microtubules of the ...
Riparbelli, Maria Giovanna; Callaini, Giuliano; Glover, David M.; Avides, Maria do CarmoDrosophila abnormal spindle (asp) mutants exhibit a mitotic metaphase checkpoint arrest with abnormal spindle poles, which reflects a requirement for Asp for the integrity of microtubule organising centres. In male meiosis, the absence of a strong spindle integrity checkpoint enables asp mutant cells to proceed through telophase. However, the central spindle region is not correctly organised and cells frequentl...
