Tracking the Ancestry of Known and ‘Ghost’ Homeologous Subgenomes in Model Grass Brachypodium Polyploids

bioRxiv, 2021
Unraveling the evolution of plant polyploids is a challenge when their diploid progenitor species are extinct or unknown or when their progenitor genome sequences are unavailable.

Population Genetics of Odontarrhena (Brassicaceae) from Albania: The Effects of Anthropic Habitat Disturbance, Soil, and Altitude on a Ni-Hyperaccumulator Plant Group from a Major Serpentine Hotspot

Plants, 2020
Albanian taxa and populations of the genus Odontarrhena are most promising candidates for research on metal tolerance and Ni-agromining, but their genetic structure remains unknown.

The Effect of Trifluralin on Post-in vitro Morphogenesis of Five Genotypes of Head Cabbage (Brassica oleraceae var. capitata)

Journal of Horticultural Research, 2021
Six genotypes of head cabbage (‘Flexima’, ‘Mutsuma’, ‘Septima’, ‘Zeus’, DC6, ‘Ancoma’) have been studied to find an effective method of obtaining polyploids using trifluralin.

Continuous Mapping Identifies Loci Associated With Weevil Resistance [Cosmopolites sordidus (Germar)] in a Triploid Banana Population

Frontiers in Plant Science, 2021
The first step toward marker-assisted selection is linking the phenotypes to molecular markers through quantitative trait loci (QTL) analysis. While the process is straightforward in self-pollinating diploid (2x) species, QTL analysis in polyploids ...

DNA repair- and nucleotide metabolism-related genes exhibit differential CHG methylation patterns in natural and synthetic polyploids (Brassica napus L.)

Horticulture Research, 2021
Polyploidization plays a crucial role in the evolution of angiosperm species. Almost all newly formed polyploids encounter genetic or epigenetic instabilities.

Paleo-Polyploidization in Lycophytes

Genomics, Proteomics & Bioinformatics, 2020
Abstract Lycophytes and seed plants constitute the typical vascular plants. Lycophytes have been thought to have no paleo-polyploidization although the event is known to be critical for the fast expansion of seed plants. Here, genomic analyses including the homologous gene dot plot analysis detected multiple paleo-polyploidization events,

In Vitro Polyploidization of Brassolaeliocattleya Hybrid Orchid

Plants, 2023
The Cattleya (Orchidaceae–Laeliinae subtribe) intergeneric hybrids, such as Brassolaeliocattleya (Blc.), have great ornamental value, due to their compact-size, with large and high color diversity of flowers.

Genomics of Evolutionary Novelty in Hybrids and Polyploids

Frontiers in Genetics, 2020
It has long been recognized that hybridization and polyploidy are prominent processes in plant evolution. Although classically recognized as significant in speciation and adaptation, recognition of the importance of interspecific gene flow has ...

Angiosperm polyploids and their road to evolutionary success [PDF]

, 2010
application/pdfThe abundance of polyploidy among flowering plants has long been recognized, and recent studies have uncovered multiple ancient polyploidization events in the evolutionary history of several angiosperm lineages.
