We begin this review by defining replicated evolution and the theoretical, genetic, and ecological concepts that help explain it. We then focus our attention on empirical cases of replicated evolution at the phenotypic and genotypic levels.
The subject of this chapter is chromosomal DNA replication in higher plants. The discussion purposely is limited to results obtained with plants. References to viruses, plasmids, organelles, yeast, and other types of cells are few.
24 paź 2017 · Repetitive DNA sequences, which represent a conspicuous fraction of every eukaryotic genome, particularly in plants, are found to be tightly linked with plant chromosome evolution. Different classes of repetitive sequences have distinct distribution patterns on the chromosomes.
29 paź 2015 · Replication precisely duplicates the chromosomal DNA molecules, and checkpoint control ensures partition of the duplicated chromosomes to daughter cells only after all DNA damage is repaired, leading to constant properties of chromosomal DNA among tissues during development from embryo to adult.
16 mar 2017 · The system is formed by the sequential recruitment of proteins to DNA replication origins, establishing the pre-replication complex (pre-RC). It represents the key process in controlling chromosome replication.
28 wrz 2015 · Polyploidy is a common event in plants that involves the acquisition of more than two complete sets of chromosomes. Allopolyploidy originates from interspecies hybrids while autopolyploidy originates from intraspecies whole genome duplication (WGD) events.
1 kwi 2020 · Endoreplication, also called endoreduplication or endopolyploidization, is a cell cycle variant in which the genome is re-replicated in the absence of mitosis causing cellular polyploidization.
