They showed that when these cells experience warmer temperatures and get more nutrients they can double or triple their cell division rates, allowing them to potentially bloom into a large population fairly quickly at sea.

However, Dr Pullen and his team present evidence that plant growth is actually «sink - limited,» meaning that genetic regulation and cell division rates have a much bigger role in controlling plant growth than previously thought: «We are proposing that plant growth is not physically limited by Net Primary Productivity (NPP) or the environment, but instead is limited genetically in response to these signals to ensure they do not become limiting.»

Our results show that trangenerational epigenetic effects play a role in adaptive evolution, and suggest that the relationship between changes in methylation patterns and differences in evolutionary outcomes, at least for quantitative traits such as cell division rates, is complex.

The time from initiation to division is given by the individual cells growth rate, which is variable and is the major cause of the variation in cell sizes.

Variability in single - cell organisms is characterized by differences in generation time — the time from birth to division — and differences in cell biomass growth rate.

Cancer is an extremely complex biological phenomenon showing enormous variability (e.g., age of patient, cell of origin, general health status, genetic background, location in an organ, nutritional status, presence or absence of continued development of neoplasia (i.e., carcinogenesis), presence or absence of enhancers, rate of growth and division, type and dosage of therapy administered, etc.).
