Morphological and Genome-Wide Evidence of Homoploid Hybridisation in Urospermum (Asteraceae)
Plants, 2022 The genus Urospermum is distributed in the Mediterranean region and Macaronesia, and has been introduced to other extra-Mediterranean regions. Although the two species constituting the genus, U. dalechampii and U. picroides, are frequently found together,

Evolution of genome size in the angiosperms [PDF]
American Journal of Botany, 2003 Genome size varies extensively across the flowering plants, which has stimulated speculation regarding the ancestral genome size of these plants and trends in genome evolution. We investigated the evolution of C‐values across the angiosperms using a molecular phylogenetic framework and C‐values not previously available for crucial basal angiosperms ...

Anales del Jardín Botánico de Madrid, 2017 Festuca subgen. Schedonorus is a group of broad-leaved fescues, which can be divided into two clades: European and Maghrebian. We employed fluorescent in situ hybridization —FISH— with probes specific for 5S and 35S ribosomal DNA and genome size ...

Genome size of Mycoplasma genitalium [PDF]
Journal of Bacteriology, 1990 The genome size of Mycoplasma genitalium was determined by using restriction enzymes that infrequently cut its DNA. The calculated value of 577 to 590 kilobases is one-fourth smaller than the genome of Mycoplasma pneumoniae, which is considered among the smallest genomes of self-replicating organisms.

Genome size determination of Scirpus mariqueter and its related species
Guangxi Zhiwu, 2023 Genome size is an important feature of a species’ genome and is usually measured by the DNA C-value, which can be used for quickly testing genome ploidy and provide an important basis for taxonomy and evolutionary biology. Scirpus mariqueter is a species

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Genome size variation in Tardigrada [PDF]
Zoological Journal of the Linnean Society, 1996 Abstract The genome size of tardigrades has been documented to date in seven species of eutardigrades, and it is among the lowest in invertebrates. In this paper the evaluation of genome size is extended to eight other species of eutardigrades and to one species of heterotardigrades, in order to obtain a more comprehensive picture of minimum DNA ...

Retrotransposon Proliferation Coincident with the Evolution of Dioecy in Asparagus
G3: Genes, Genomes, Genetics, 2016 Current phylogenetic sampling reveals that dioecy and an XY sex chromosome pair evolved once, or possibly twice, in the genus Asparagus. Although there appear to be some lineage-specific polyploidization events, the base chromosome number of 2n = 2× = 20

The C-value enigma and timing of the Cambrian explosion
, 2008 The Cambrian explosion is a grand challenge to science today and involves multidisciplinary study. This event is generally believed as a result of genetic innovations, environmental factors and ecological interactions, even though there are many ...
