The interplay between the energetic cost of a cellular structure and its evolutionary fate is a subject that will become increasingly important as evolutionary cell biology matures as a science.
10 cze 2019 · All cellular structures are assembled from molecular building blocks, and molecular building blocks incur energetic costs to the cell. In an energy-limited environment, the energetic cost of a...
10 cze 2019 · All cellular structures are assembled from molecular building blocks, and molecular building blocks incur energetic costs to the cell. In an energy-limited environment, the energetic cost of a cellular structure imposes a fitness cost and impacts a cell’s evolutionary trajectory.
12 gru 2015 · Contrary to this latter view, analysis of cellular energetics and genomics data from a wide variety of species indicates that, relative to the lifetime ATP requirements of a cell, the costs of a gene at the DNA, RNA, and protein levels decline with cell volume in both bacteria and eukaryotes.
Evolutionary cell biology requires information on the bioenergetic costs of various cell structures and functions to clarify when the evolutionary benefits of cell features outweigh the baseline costs of investment.
26 lip 2022 · Paths of flagellar evolution depend on the deviations between fitness gains and energy costs. Using structural data available for all three major flagellar types (bacterial, archaeal, and eukaryotic), flagellar construction costs were determined for Escherichia coli, Pyrococcus furiosus, and Chlamydomonas reinhardtii.
1 lut 2024 · I propose that the early evolution of new genes with weak functions imposes higher energetic costs by overexpression before their functions are evolutionarily refined. In the long term, the accumulation of new genes deviates resources away from growth and reproduction.
