Does Cell Size Impact Chloroplast Genome Size?
There is a strong positive relationship between nuclear genome size and cell size across the eukaryotic domain, but the cause and effect of this relationship is unclear. A positive coupling of cell size and DNA content has also been recorded for various bacteria, suggesting that, with some exceptions, this association might be universal throughout the tree of life. However, the link between cel...
متن کاملEmbryogenesis: Coordinating Cell Division with Gastrulation
Embryogenesis requires the production of sufficient cells, the correct placement of these cells within the embryo and the assignment to them of appropriate identities. Complications arise because cell division and cell migration seem incompatible. Mitosis requires the assembly and disassembly of a complex microtubule network to ensure faithful DNA segregation, and cytokinesis requires remodelin...
متن کاملCoordinating cell polarity with cell division in space and time.
Decisions of when and where to divide are crucial for cell survival and fate, and for tissue organization and homeostasis. The temporal coordination of mitotic events during cell division is essential to ensure that each daughter cell receives one copy of the genome. The spatial coordination of these events is also crucial because the cytokinetic furrow must be aligned with the axis of chromoso...
متن کاملEffects of whole genome duplication on cell size and gene expression in mouse embryonic stem cells
Alterations in ploidy tend to influence cell physiology, which in the long-term, contribute to species adaptation and evolution. Polyploid cells are observed under physiological conditions in the nerve and liver tissues, and in tumorigenic processes. Although tetraploid cells have been studied in mammalian cells, the basic characteristics and alterations caused by whole genome duplication are s...
متن کاملGenome size
Materials and Methods Genome Size The haploid genome size (C-value, in pg) of 1461 ray-finned fish species (Actinopterygii) was downloaded from the Animal Genome Size Database (www.genomesize.com). Unless otherwise stated, comparisons of genome sizes are performed on the C-values, which can be converted to number of base pairs by the following: number of base pairs = C-value × 0.978 × 109. Seve...
