Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

open access: yes, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Wider geographic distribution and higher diversity of hexaploids than tetraploids in Carassius species complex reveal recurrent polyploidy effects on adaptive evolution

open access: yesScientific Reports, 2017
Polyploidy roles on adaptive evolution and ecological novelty have been extensively studied in plants but remained unclear in vertebrates owing to the rare polyploidy incidences.

Oryzalin-induced polyploidy in Vanda limbata (Blume): Phenotypic assessment

open access: yesActa Biochimica Indonesiana
Background: Vanda limbata is a natural orchid species found on Java Island, commonly known as V. limbata 'Jawa.' Enhancing plant vigor is essential to increase its potential as an ornamental plant, with one promising approach being induced polyploidy ...

Polyploidy Index and Its Implications for the Evolution of Polyploids

open access: yesFrontiers in Genetics, 2019
Polyploidy has contributed to the divergence and domestication of plants; however, estimation of the relative roles that different types of polyploidy have played during evolution has been difficult.

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.

Comparative DNA-methylome and transcriptome analysis reveals heterosis- and polyploidy-associated epigenetic changes in rice

open access: yesCrop Journal, 2023
Heterosis and polyploidy have an overwhelming influence on plant evolution. Recently, polyploid rice hybrids have been used to breed new rice varieties because they combine the advantages of both heterosis and polyploidy.

Features of the Genetic Structure of the Earthworms Aporrectodea (Superspecies) Caliginosa (Oligochaeta: Lumbricidae) Complex in Ukraine [PDF]

open access: yes, 2008
An investigation of the genetic structure of the Aporrectodea caliginosa – A. trapezoids diploidpolyploid complex of earthworms found in the Ukraine is performed by means of biochemical genetic marking with respect to six loci (Aat, Es-1, -2, -3, and -4,
