Turning Meiosis into Mitosis
Apomixis, or asexual clonal reproduction through seeds, is of immense interest due to its potential application in agriculture. One key element of apomixis is apomeiosis, a deregulation of meiosis that results in a mitotic-like division. We isolated and characterised a novel gene that is directly involved in controlling entry into the second meiotic division. By combining a mutation in this gen...
متن کاملMitosis and Meiosis
Introduction As we discussed in class, biological growth is a multi-dimensional phenomena. In essence, the basic unit of life, the cell, must duplicate itself. One "mother" cell must become two "daughter" cells, through the process of Cell Division, mostly MITOSIS. This is a completely asexual event and involves replication of the nucleus and its constituents and dividing up of the cytoplasm, t...

متن کاملThe evolution of meiosis from mitosis.
THE origins of meiosis in early eukaryotic history have never been satisfactorily explained. Since the reduction-division process in meiosis is essential for sexual life cycles, discussion of the origins of meiosis has been closely tied to debates about the evolutionary value of sex itself and the selective pressures for its maintenance. Yet the cytological events involved in the origins of mei...
متن کاملChromosome cohesion in mitosis and meiosis.
During mitosis and meiosis sister chromatids are held together by protein complexes. This cohesion is important not only for pairwise alignment of chromosomes on the mitotic spindle but also for the generation of tension across centromeres – it counteracts the pulling force of spindle microtubules, which ensures the bipolar attachment of chromosomes. Chromosome cohesion thus enables accurate ch...
