Divergent evolutionary paces among eudicot plants revealed by simultaneously duplicated genes produced billions of years ago

Frontiers in Plant Science
Polyploidization often occurs more than once along an evolutionary lineage to form extant plants. Major core eudicot plants share a whole-genome triplication (ceWGT), through which thousands of simultaneously duplicated genes are retained in extant ...

Polyploid Gene Expression and Regulation in Polysomic Polyploids

American Journal of Plant Sciences, 2019
Polyploidization is one of the most crucial pathways in introducing speciation and broadening biodiversity, especially in the Plant Kingdom. Although the majority of studies have focused only on allopolyploid or disomic polyploids, polysomic polyploid species have occurred frequently in higher plants.

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 ...

In Vitro Synthetic Polyploidization in Medicinal and Aromatic Plants for Enhanced Phytochemical Efficacy—A Mini-Review

Agronomy
Medicinal and aromatic plants (MAPs) are well known for their valuable secondary metabolites and diverse phytochemicals responsible for a plethora of medicinal properties such as antimicrobial, antioxidant, anti-inflammatory, anticancerous, and analgesic

Nitrous Oxide Treatment after Pollination Induces Ploidy Changes in Statice (Limonium sp.)

Horticulturae
The production of statice (Limonium sp.) plants with higher ploidy through induction of whole-genome duplication (WGD) via the spindle disrupter nitrous oxide (N2O) was examined as a strategy to increase the germplasm diversity of the species ...

Alignment of Common Wheat and Other Grass Genomes Establishes a Comparative Genomics Research Platform

Frontiers in Plant Science, 2017
Grass genomes are complicated structures as they share a common tetraploidization, and particular genomes have been further affected by extra polyploidizations.

Polyploid Speciation

, 2016
Genome duplication represents a dramatic, yet relatively common, genomic change, having occurred in the evolutionary history of angiosperms, vertebrates, and yeast, among many other groups. The result of such duplications ('polyploidy,' the existence of multiple sets of chromosomes within the genome) has long been recognized and was implicated as a ...

Polyploidy-mediated resilience in hepatic aging: molecular mechanisms and functional implication

Egyptian Liver Journal
Background Polyploidization, a process where cells acquire additional chromosome sets, is a unique characteristic of hepatocytes. This process has been increasingly recognized as an adaptive mechanism for maintaining liver function during aging, a period

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

Acta 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 ...
