Illegitimate Recombination Between Homeologous Genes in Wheat Genome

Frontiers in Plant Science, 2020
Polyploidies produce a large number of duplicated regions and genes in genomes, which have a long-term impact and stimulate genetic innovation. The high similarity between homeologous chromosomes, forming different subgenomes, or homologous regions after

Naturally Occurring Triploidy in Cannabis

Plants, 2023
Polyploidy is a significant evolutionary process in plants that involves the duplication of genomic content and has been recognized as a key mechanism driving plant diversification and adaptation.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Regulation and function of developmentally controlled polyploidization [PDF]

, 2021
The development of a multicellular organism requires intricate regulation of cellular behaviour, especially on the cell division cycle. While we have a lot of knowledge on how cells make the decision to divide, insight on how cell cycle alterations are ...

Cultivar‐Specific Production of Unreduced Pollen in the Ornamental Bigleaf Hydrangea (Hydrangea macrophylla ssp. macrophylla)

Plant Breeding, EarlyView.
ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Polyploidization using colchicine in horticultural plants: A review

, 2019
Polyploidization of plants occurs in nature but it is a slow and gradual process that has driven evolution and speciation throughout the ages. As time is important, polyploidization can be induced in a shorter period by using colchicine that interferes ...

Transcriptional characterization of human megakaryocyte polyploidization and lineage commitment. [PDF]

, 2021
BACKGROUND: Megakaryocytes (MKs) originate from cells immuno-phenotypically indistinguishable from hematopoietic stem cells (HSCs), bypassing intermediate progenitors.
