Polyploidy induction in Phlox paniculata L. under in vitro conditions

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
The objective of this work was to find an effective method of polyploidy induction using chemomutagens, colchicine and oryzalin, in diploid cultivar of Phlox paniculata ‘Fujiyama’ (syn. Mt. Fuji, Fuji).

Characterization and Stress Response of the JmjC Domain-Containing Histone Demethylase Gene Family in the Allotetraploid Cotton Species Gossypium hirsutum

Plants, 2020
Histone modification is an important epigenetic modification that controls gene transcriptional regulation in eukaryotes. Histone methylation is accomplished by histone methyltransferase and can occur on two amino acid residues, arginine and lysine ...

MicroRNA-122 Regulates Polyploidization in the Murine Liver

, 2017
A defining feature of the mammalian liver is polyploidy, a numerical change in the entire complement of chromosomes. The first step of polyploidization involves cell division with failed cytokinesis. Although polyploidy is common, affecting similar to 90%

Generation and Characterization of a Sexual Tetraploid Genotype of Seashore Paspalum (Paspalum vaginatum) for Novel Breeding Strategies

Plants
Breeding Paspalum vaginatum has been limited to the diploid germplasm; however there is a rich diversity in closely related species that may be utilized. The species is diploid and outcrossing due to self-incompatibility.

Production of compact petunias through polyploidization [PDF]

, 2017
Petunia, a commercially important ornamental plant worldwide, has been subjected to breeding programs that have yielded a high number of varieties. One of the key factors in the commercial value of these varieties is plant compactness. Currently, compact

Deciphering the Mechanisms Underlying Enhanced Drought Tolerance in Autotetraploid Apple ‘Redchief’: Physiological, Biochemical, Molecular, and Anatomical Insights

Agronomy
It is generally believed that plant polyploids exhibit greater tolerance to abiotic stress conditions than their diploid counterparts. The aim of the present research was to investigate the mechanisms underlying enhanced drought tolerance in the ...

Phylogenomics of the olive tree (Olea europaea) reveals the relative contribution of ancient allo- and autopolyploidization events

BMC Biology, 2018
Background Polyploidization is one of the major evolutionary processes that shape eukaryotic genomes, being particularly common in plants. Polyploids can arise through direct genome doubling within a species (autopolyploidization) or through the merging ...

Factors regulating megakaryocyte progenitor commitment to polyploidization.

, 1995
peer reviewedRecognizable megakaryocytes are polyploid cells generated by a clonogenic, diploid progenitor, termed CFU-MKC (colony forming unit, megakaryocyte).

Genetic significance of mode of polyploidization: somatic doubling or 2n gametes?

, 1991
Computer simulation was undertaken to compare the genetic consequences of asexual (somatic doubling) and sexual (2n gametes) polyploidization. The coefficient of inbreeding at a locus, the number and frequency of genotypes at a locus, and the proportion

Data from: Phylogenetic evidence for cladogenetic polyploidization in land plants

, 2016
Premise of the study: Polyploidization is a common and recurring phenomenon in plants and is often thought to be a mechanism of "instant speciation." Whether polyploidization is associated with the formation of new species ("cladogenesis") or simply ...
