Telomerase RNA gene paralogs in plants – the usual pathway to unusual telomeres

New Phytologist, Volume 239, Issue 6, Page 2353-2366, September 2023., 2023
Summary Telomerase, telomeric DNA and associated proteins together represent a complex, finely tuned and functionally conserved mechanism that ensures genome integrity by protecting and maintaining chromosome ends. Changes in its components can threaten an organism's viability.

Nanopore sequencing technology and its applications

MedComm, Volume 4, Issue 4, August 2023., 2023
Nanopore sequencing has been instrumental in managing the COVID‐19 pandemic. This review aims to increase public understanding of its role in identifying SARS‐CoV‐2 variants and tracking changes in regional epidemiology. Additionally, the review explores the use of nanopore sequencing in detecting other microbial outbreaks, as well as its applications ...

Genome size variation within Crithmum maritimum: Clues on the colonization of insular environments

Ecology and Evolution, Volume 13, Issue 4, April 2023., 2023
Angiosperms present an astonishing diversity of genome sizes that can vary intra‐ or interspecifically. Patterns of cytogenomic diversity were assessed among geographic samples (ca. 114) of Crithmum maritimum (Apiaceae), collected across Azores and Madeira archipelagos, as well as in adjacent continental areas.

Mega‐sized pericentromeric blocks of simple telomeric repeats and their variants reveal patterns of chromosome evolution in ancient Cycadales genomes

The Plant Journal, Volume 112, Issue 3, Page 646-663, November 2022., 2022
Significance Statement Telomeric sequences, typically found at chromosome ends, play an essential role in genome integrity. We studied their abundance across land plants and observe large blocks of telomeric repeats at centromere positions, particularly on telocentric chromosomes of cycads.

Reference standards for flow cytometric estimation of absolute nuclear DNA content in plants

Cytometry Part A, Volume 101, Issue 9, Page 710-724, September 2022., 2022
Abstract The estimation of nuclear DNA content has been by far the most popular application of flow cytometry in plants. Because flow cytometry measures relative fluorescence intensities of nuclei stained by a DNA fluorochrome, ploidy determination, and estimation of the nuclear DNA content in absolute units both require comparison to a reference ...

Genome downsizing after polyploidy: mechanisms, rates and selection pressures

The Plant Journal, Volume 107, Issue 4, Page 1003-1015, August 2021., 2021
SUMMARY An analysis of over 10 000 plant genome sizes (GSs) indicates that most species have smaller genomes than expected given the incidence of polyploidy in their ancestries, suggesting selection for genome downsizing. However, comparing ancestral GS with the incidence of ancestral polyploidy suggests that the rate of DNA loss following polyploidy ...

Which factors contribute most to genome size variation within angiosperms?

Ecology and Evolution, Volume 11, Issue 6, Page 2660-2668, March 2021., 2021
Genome size is a biodiversity trait that shows staggering diversity across the flowering plants, which plays an important role in shaping the evolution of plants. Here, we scan the genomic information of 54 species from 52 families covering the major groups of angiosperms and evaluate the correlation between variations of genome sizes and different ...
