Origination, expansion, evolutionary trajectory, and expression bias of AP2/ERF superfamily in Brassica napus

Frontiers in Plant Science, 2016
The AP2/ERF superfamily, one of the most important transcription factor families, plays crucial roles in response to biotic and abiotic stresses. So far, a comprehensive evolutionary inference of its origination and expansion has not been available. Here,

Genome-wide characterization and analysis of Golden 2-Like transcription factors related to leaf chlorophyll synthesis in diploid and triploid Eucalyptus urophylla

Frontiers in Plant Science, 2022
Golden 2-Like (GLK) transcription factors play a crucial role in chloroplast development and chlorophyll synthesis in many plant taxa. To date, no systematic analysis of GLK transcription factors in tree species has been conducted.

Postglacial colonization and parallel evolution of metal tolerance in the polyploid Cerastium alpinum [PDF]

, 2005
The Fennoscandian flora is characterized by a high frequency of polyploids, probably because they were more successful than diploid plants in colonizing after the last Ice Age.

The Polyploid State Restricts Hepatocyte Proliferation and Liver Regeneration in Mice

Hepatology, 2019
The liver contains a mixture of hepatocytes with diploid or polyploid (tetraploid, octaploid, etc.) nuclear content. Polyploid hepatocytes are commonly found in adult mammals, representing ~90% of the entire hepatic pool in rodents.

Genome-wide DNA Methylation Profiling by Modified Reduced Representation Bisulfite Sequencing in Brassica rapa Suggests that Epigenetic Modifications Play a Key Role in Polyploid Genome Evolution

Frontiers in Plant Science, 2015
Brassica rapa includes some of the most important vegetables worldwide as well as oilseed crops. The complete annotated genome sequence confirmed its paleohexaploid origins and provides opportunities for exploring the detailed process of polyploid genome

Polyploid races, genetic structure and morphological features of earthworm Aporrectodea rosea (Savigny, 1826) (Oligohaeta: Lumbricidae) in Ukraine [PDF]

, 2011
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm A. rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking.

Polyploid plants have faster rates of multivariate niche differentiation than their diploid relatives.

Ecology Letters, 2019
Polyploid speciation entails substantial and rapid postzygotic reproductive isolation of nascent species that are initially sympatric with one or both parents.

Polyploid superficial cells that maintain the urothelial barrier are produced via incomplete cytokinesis and endoreplication [PDF]

, 2018
Summary: The urothelium is an epithelia barrier lined by a luminal layer of binucleated, octoploid, superficial cells. Superficial cells are critical for production and transport of uroplakins, a family of proteins that assemble into a waterproof ...

Polyploid Gene Expression and Regulation in Polysomic Polyploids

American Journal of Plant Sciences, 2019
Polyploidization is one of the most crucial pathways in introducing speciation and broadening biodiversity, especially in the Plant Kingdom. Although the majority of studies have focused only on allopolyploid or disomic polyploids, polysomic polyploid species have occurred frequently in higher plants.
