Genome size is a strong predictor of cell size and stomatal density in angiosperms.
Across eukaryotes phenotypic correlations with genome size are thought to scale from genome size effects on cell size. However, for plants the genome/cell size link has only been thoroughly documented within ploidy series and small subsets of herbaceous species. Here, the first large-scale comparative analysis is made of the relationship between genome size and cell size across 101 species of a...
متن کاملTotal Knee Replacement Sizing: Shoe Size Is a Better Predictor for Implant Size than Body Height
Background: Various sizes of implants need to be available during surgery. The purpose of this paper is to comparebody height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see whichbiomarker is a better predictor for preoperative planning to determine implant size.Methods: A total of 100 knees, belonging to 50 females and 50 males, were observed. P...
متن کاملStomatal vs. genome size in angiosperms: the somatic tail wagging the genomic dog?
BACKGROUND AND AIMS Genome size is a function, and the product, of cell volume. As such it is contingent on ecological circumstance. The nature of 'this ecological circumstance' is, however, hotly debated. Here, we investigate for angiosperms whether stomatal size may be this 'missing link': the primary determinant of genome size. Stomata are crucial for photosynthesis and their size affects fu...
متن کاملEvaluating the role of genome downsizing and size thresholds from genome size distributions in angiosperms.
PREMISE OF THE STUDY Whole-genome duplications (WGDs) can rapidly increase genome size in angiosperms. Yet their mean genome size is not correlated with ploidy. We compared three hypotheses to explain the constancy of genome size means across ploidies. The genome downsizing hypothesis suggests that genome size will decrease by a given percentage after a WGD. The genome size threshold hypothesis...
متن کاملGenome Size Is a Strong Predictor of Root Meristem Growth Rate
Variation in genome size (GS) has been linked to several facets of the plant phenotype. Recently it was shown that GS is significantly correlated with cell size and the duration of the cell cycle. Here we test the hypothesis that GS might also be a predictor of apical root meristem growth rate (RMGR). We studied eight species of eudicots with varying GS using time-lapse microscopic image analys...
