Phylogenetic conservation of chromosome numbers in Actinopterygiian fishes. [PDF]

open access: yes, 2006
The genomes of ray-finned fishes (Actinopterygii) are well known for their evolutionary dynamism as reflected by drastic alterations in DNA content often via regional and whole-genome duplications, differential patterns of gene silencing or loss, shifts ...

Autotetraploid plant production in endemic Onobrychis elata with colchicine treatments

open access: yesJournal of Applied Botany and Food Quality, 2019
This study aimed to induce autotetraploidy in endemic Onobrychis elata plants by colchicine treatment of seeds or seedlings. Colchicine was applied to O. elata directly on germinated seeds, pre-germinated seeds (root length of 3-8 mm), and apical regions

Origin and evolution of the octoploid strawberry genome. [PDF]

open access: yes, 2019
Cultivated strawberry emerged from the hybridization of two wild octoploid species, both descendants from the merger of four diploid progenitor species into a single nucleus more than 1 million years ago.

Tetraploidy-associated centrosome overduplication in mouse early embryos

open access: yesCommunicative & Integrative Biology, 2018
Recently, we observed that tetraploidization of certain types of human cancer cells resulted in upregulation of centrosome duplication cycles and chronic generation of the extra centrosome. Here, we investigated whether tetraploidy-linked upregulation of

Notch Activation Is Associated with Tetraploidy and Enhanced Chromosomal Instability in Meningiomas

open access: yesNeoplasia: An International Journal for Oncology Research, 2008
The Notch signaling cascade is deregulated in diverse cancer types. Specific Notch function in cancer is dependent on the cellular context, the particular homologs expressed, and cross-talk with other signaling pathways.

Characterization of Expression of the KCNE Gene Family in Zebrafish, Danio rerio [PDF]

open access: yes, 2011
The KCNE gene family codes for five transmembrane accessory proteins, minK related peptides or Mirps, involved in the modification of voltage-gated potassium (Kv) channels, K+ selective pores vital in the regulation of membrane potential and ...

Hyla versicolor-chrysoscelis Species Complex of Gray Treefrogs in Arkansas: Histological and Ultrastructural evidence [PDF]

open access: yes, 1987
We investigated the Hyla versicolor-chrysoscelis species complex (tetraploid and diploid species, respectively) of cryptic gray treefrogs from Arkansas using light and scanning electron microscopy.
