Characterization of Repetitive DNA in Saccharum officinarum and Saccharum spontaneum by Genome Sequencing and Cytological Assays

Frontiers in Plant Science, 2022
In most plant species, DNA repeated elements such as satellites and retrotransposons are composing the majority of their genomes. Saccharum officinarum (2n = 8x = 80) and S.

Postglacial colonization and parallel evolution of metal tolerance in the polyploid Cerastium alpinum [PDF]

, 2005
The Fennoscandian flora is characterized by a high frequency of polyploids, probably because they were more successful than diploid plants in colonizing after the last Ice Age.

In vitro evidence for senescent multinucleated melanocytes as a source for tumor-initiating cells [PDF]

, 2015
Oncogenic signaling in melanocytes results in oncogene-induced senescence (OIS), a stable cell-cycle arrest frequently characterized by a bi- or multinuclear phenotype that is considered as a barrier to cancer progression.

The Crosstalk Between CRL5 and APC/C E3 Ligases Regulates Metastasis and Chemosensitivity of Cancer Cells

Advanced Science, EarlyView.
This study uncovers a previously unknown crosstalk between two major ubiquitin ligases, CRL5 and APC/C. The authors identify APC11 as a binding partner of CUL5, showing that their interaction regulates neddylation, substrate stability, and mitotic progression.

Integrated Analysis of Phenotypic and Hepatic Transcriptomic Profiles Reveals Enhanced Cold Tolerance in Triploid Crucian Carp

Fishes
Cold stress poses a critical threat to fish survival by triggering metabolic dysfunction, oxidative damage, immune suppression, and apoptosis. However, hybrid polyploid fish triploid crucian carp (3nRCR, 3n = 150) demonstrate superior stress tolerance ...

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, EarlyView.
Summary The presence of two or more copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. The Amazonian tree flora is the most species‐rich on Earth and largely arose as a result of rapid evolutionary radiations. While polyploidy is an important catalyst

Polyploid races, genetic structure and morphological features of earthworm Aporrectodea rosea (Savigny, 1826) (Oligohaeta: Lumbricidae) in Ukraine [PDF]

, 2011
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm A. rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking.

A Forward Genetics Strategy for High‐Throughput Gene Identification via Precise Image‐Based Phenotyping of an Indexed EMS Mutant Library

Advanced Science, EarlyView.
The GeneHunter‐Gene‐Level Association (GH‐GLA) pipeline enables high‐throughput gene identification in an indexed EMS population of wheat cultivar KN9204. It identifies 5905 trait‐associated wheat genes and validates key regulators of kernel weight and spikelet architecture via gene editing and haplotype analysis.

Molecular Phylogenetics of Seven Cyprinidae Distant Hybrid Lineages: Genetic Variation, 2nNCRC Convergent Evolution, and Germplasm Implications

Biology
Distant hybridization is key to trait innovation and speciation, with Cyprinidae hybrid phylogeny helping to clarify diversification mechanisms. Yet, a major gap persists in Cyprinidae studies: the stabilization mechanisms of interspecific distant hybrid
