Nucleolar Dominance in a Tetraploidy Hybrid Lineage Derived From Carassius auratus red var. () × Megalobrama amblycephala () [PDF]

open access: yesFrontiers in Genetics, 2018
Nucleolar dominance is related to the expression of 45S rRNA genes inherited from one progenitor due to the silencing of the other progenitor’s rRNA genes.

A hybrid sub-lineage of Listeria monocytogenes comprising hypervirulent isolates [PDF]

open access: yesNature Communications, 2019
Listeria monocytogenes isolates are highly heterogeneous and exhibit different levels of virulence. Here, the authors identify hypervirulent isolates that represent a hybrid sub-lineage of the major lineage II harbouring virulence factors from Listeria ...

A hybrid Ornstein–Uhlenbeck–Branching framework unifies microbial and pediatric tumor evolution [PDF]

open access: yesFrontiers in Oncology
IntroductionPediatric tumors can relapse despite low mutation burdens, suggesting hybrid evolutionary dynamics shaped by stochastic variability and stabilizing forces.

Establishment and Biological Characteristics Analysis of a Hybrid Culter Lineage from Megalobrama amblycephala (♀) and Culter alburnus (♂) [PDF]

open access: yesAnimals
Culter alburnus (topmouth culter, TC) is extensively distributed in various rivers and lakes in China. As a widely adaptive fish species, they have significant economic value and special ecological roles.

Optimization Techniques to Deeply Mine the Transcriptomic Profile of the Sub-Genomes in Hybrid Fish Lineage

open access: yesFrontiers in Genetics, 2019
It has been shown that reciprocal cross allodiploid lineage with sub-genomes derived from the cross of Megalobrama amblycephala (BSB) × Culter alburnus (TC) generates the variations in phenotypes and genotypes, but it is still a challenge to deeply mine ...

Genomic characterization of Enterotoxigenic Escherichia coli lineage 2 (CS2 + CS3) by long-read sequencing reveals distinct lineage-specific genome organization [PDF]

open access: yesScientific Reports
Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhoea in children, adults and travellers in endemic regions. ETEC pathogenesis is mediated by heat-labile (LT) and heat-stable (ST) enterotoxins together with colonization factors.

The rapid variation of Hox clusters reveals a clear evolutionary path in a crucian carp-like homodiploid fish lineage

open access: yesReproduction and Breeding, 2021
The surprising variation in the number of Hox clusters and genome structure in ray-finned fish lineages reflects the history of duplications and subsequent lineage-specific gene loss.

Repeated Reticulate Evolution in North American Papilio machaon Group Swallowtail Butterflies. [PDF]

open access: yesPLoS ONE, 2015
Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity. However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of ...

First cytogenetic register of an allopolyploid lineage of the genus Aeschynomene (Leguminosae, Papilionoideae) native to Mexico

open access: yesCaryologia, 2021
A conventional cytogenetics analysis revealed for first time an allopolyploid lineage of the genus Aeschynomene in Mexico. The hybrid condition is confirmed after all the prometaphase and metaphase nuclei of the hybrids exhibited only one pair of SAT ...

The ascomycete Verticillium longisporum is a hybrid and a plant pathogen with an expanded host range. [PDF]

open access: yesPLoS ONE, 2011
Hybridization plays a central role in plant evolution, but its overall importance in fungi is unknown. New plant pathogens are thought to arise by hybridization between formerly separated fungal species.
