Evolutionary Advantage of Cell Size Control. [PDF]

Phys Rev Lett
We analyze the advantage of cell size control strategies in growing populations under mortality constraints. We demonstrate a general advantage of the adder control strategy in the presence of growth-dependent mortality, and for different size-dependent mortality landscapes.

Rapamycin supplementation of Drosophila melanogaster larvae results in less viable adults with smaller cells

Royal Society Open Science, 2023
The intrinsic sources of mortality relate to the ability to meet the metabolic demands of tissue maintenance and repair, ultimately shaping ageing patterns.

Genome Size and Labellum Epidermal Cell Size Are Evolutionarily Correlated With Floral Longevity in Paphiopedilum Species

Frontiers in Plant Science, 2021
Genome size is known to influence phenotypic traits in leaves and seeds. Although genome size is closely related to cellular and developmental traits across biological kingdoms, floral longevity is a floral trait with important fitness consequence, but ...

Control of Cell Size by c-di-GMP Requires a Two-Component Signaling System in the Cyanobacterium Anabaena sp. Strain PCC 7120

Microbiology Spectrum, 2023
Each bacterial species possesses a specific cell size and morphology, which constitute important and recognizable physical traits. How bacteria maintain their particular cell size and morphology remains an essential question in microbiology ...

Conserved cellular patterning in the mesophyll of rice leaves

Plant Direct, 2023
The mesophyll cells of grass leaves, such as rice, are traditionally viewed as displaying a relatively uniform pattern, in contrast to the clear distinctions of palisade and spongy layers in typical eudicot leaves. This quantitative analysis of mesophyll

Cell-Size Control [PDF]

Cold Spring Harbor Perspectives in Biology, 2015
Cells of a given type maintain a characteristic cell size to function efficiently in their ecological or organismal context. They achieve this through the regulation of growth rates or by actively sensing size and coupling this signal to cell division.

The cell cycle inhibitor RB is diluted in G1 and contributes to controlling cell size in the mouse liver

Frontiers in Cell and Developmental Biology, 2022
Every type of cell in an animal maintains a specific size, which likely contributes to its ability to perform its physiological functions. While some cell size control mechanisms are beginning to be elucidated through studies of cultured cells, it is ...

MYB3R-SCL28-SMR module with a role in cell size control negatively regulates G2 progression in Arabidopsis

Plant Signaling & Behavior, 2023
Cell size control is one of the prerequisites for plant growth and development. Recently, a GRAS family transcription factor, SCARECROW-LIKE28 (SCL28), was identified as a critical regulator for both mitotic and postmitotic cell-size control.

A Competitive Advantage of Middle-Sized Diatoms From Increasing Seawater CO2

Frontiers in Microbiology, 2022
Diatoms, one of the most important phytoplankton groups, fulfill their carbon demand from seawater mainly by obtaining passively diffused carbon dioxide (CO2) and/or actively consuming intracellular energy to acquire bicarbonate (HCO3–).

Dynamics of cell mass and size control in multicellular systems and the human body

Journal of Biological Research - Thessaloniki, 2022
Cellular processes, in particular homeostasis and growth, require an intricate and complex exchange of matter between a cell and its surroundings. Yet experimental difficulties have prevented a detailed description of the dynamics of a cell’s mass and ...
