Meiotic chromosome movements in plants, a puppet show?
Meiosis is a special type of cell division by which sexually reproducing organisms maintain their chromosome number across generations. This process produces haploid gametes by two successive rounds of cell division preceded by a unique DNA replication event. During the first meiotic prophase, the homologous chromosomes form stable bivalents, a process which implies their recognition, with a su...
متن کاملMeiotic Chromosome Organization and Segregation in Plants.
During meiosis, homologous chromosomes are brought together to be recombined and segregated into separate haploid gametes. This requires two cell divisions, an elaborate prophase with five substages, and specialized mechanisms that regulate the association of sister chromatids. This review focuses on plant chromosomes and chromosome-associated structures, such as recombination nodules and kinet...
متن کاملPuppet Show: Intuitive Puppet Interfaces for Expressive Character Control
We argue that evolving game art like virtual performances and Machinima depend on better character control. That is why Puppet Show does not focus on new or optimized gameplay but aims to extend the expressive range of characters in an existing game world. Puppet Show is an interface plug-in for Epic’s Unreal Tournament 2004. Puppet Show uses an external Java program to feed visual input from a...
متن کاملChromosome dynamics in meiotic prophase I in plants.
Early stages of meiotic prophase are characterized by complex and dramatic chromosome dynamics. Chromosome behavior during this period is associated with several critical meiotic processes that take place at the molecular level, such as recombination and homologous chromosome recognition and pairing. Studies to characterize specific patterns of chromosome dynamics and to identify their exact ro...
متن کاملSustained and rapid chromosome movements are critical for chromosome pairing and meiotic progression in budding yeast.
Telomere-led chromosome movements are a conserved feature of meiosis I (MI) prophase. Several roles have been proposed for such chromosome motion, including promoting homolog pairing and removing inappropriate chromosomal interactions. Here, we provide evidence in budding yeast that rapid chromosome movements affect homolog pairing and recombination. We found that csm4Δ strains, which are defec...
