Genome-wide characterization and analysis of Golden 2-Like transcription factors related to leaf chlorophyll synthesis in diploid and triploid Eucalyptus urophylla

open access: yesFrontiers in Plant Science, 2022
Golden 2-Like (GLK) transcription factors play a crucial role in chloroplast development and chlorophyll synthesis in many plant taxa. To date, no systematic analysis of GLK transcription factors in tree species has been conducted.

Polyploid Speciation

open access: yes, 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 ...

Polyploidization in Liver Tissue

open access: yesThe American Journal of Pathology, 2014
Polyploidy (alias whole genome amplification) refers to organisms containing more than two basic sets of chromosomes. Polyploidy was first observed in plants more than a century ago, and it is known that such processes occur in many eukaryotes under a variety of circumstances.

Pregnancy Outcomes and Postnatal Health From Transferred Mosaic Embryos Following Preimplantation Genetic Testing for Aneuploidy

open access: yesiNew Medicine, EarlyView.
This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

Application of Flow Cytometry to Determine Cell DNA Content in the Genetic Breeding of Fish

open access: yesFishes
In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling ...

The Formation of a Novel Intergeneric Hybrid Fish Derived from Megalobrama amblycephala (♀) × Culter dabryi (♂)

open access: yesAnimals
Distant hybridization in fish serves to integrate the genetic material from two distinct, distantly related species. In this study, we successfully produced a new hybrid fish (BG) through the intergeneric hybridization of blunt snout bream (Megalobrama ...

Polyploid spermatozoa in Pityogenes chalcographus and Ips typographus (Coleoptera: Scolytidae)

open access: yesEuropean Journal of Entomology, 2004
Abnormal spermatogenesis in Pityogenes chalcographus (L.) and Ips typographus (L.) results in oversized spermatozoa in all the populations investigated. They can be identified by light microscopy and classified as 2n up to 16n polyploid.

A Tracing Model for the Evolutionary Equilibrium of Octoploids

open access: yesFrontiers in Genetics, 2022
Testing Hardy-Weinberg equilibrium (HWE) is a fundamental approach for inferring population diversity and evolution, but its application to octoploids containing eight chromosome sets has not well been justified.
