Isolation and Characterization of Microsatellites Markers in Centaurium Grandiflorum ssp. Boissieri
(Springer Nature, 2021)
Background: Estimating outcrossing/selfing rates and characterizing genetic diversity with microsatellite markers are crucial to understanding the evolution of plant mating systems. Methods and results: We developed, ...

Karyotypic diversity: a neglected trait to explain angiosperm diversification?
(Oxford, 2023-01)
Evolutionary changes in karyotype provide genetic support to organisms’ differentiation and adaptation; however, the association between karyotype diversity and species diversification in flowering plants (angiosperms) ...

Drivers of diversification in Linum (Linaceae) by means of chromosome evolution: correlations with biogeography, breeding system and habit.
(Oxford University Press, 2023-09-10)
Background and Aims Chromosome evolution leads to hybrid dysfunction and recombination patterns and has thus been proposed as a major driver of diversification in all branches of the tree of life, including flowering ...

A non-homogeneous model of chromosome-number evolution to reveal shifts in the transition patterns across the phylogeny
(Wiley-Blackwell, 2023)
Changes in chromosome numbers, including polyploidy and dysploidy events, play a key role in eukaryote evolution as they could expediate reproductive isolation and have the potential to foster phenotypic diversification. ...

Genomic Hotspots of Chromosome Rearrangements Explain Conserved Synteny Despite High Rates of Chromosome Evolution in a Holocentric Lineage
(Wiley-Blackwell, 2023)
Holocentric organisms, unlike typical monocentric organisms, have kinetochore activity distributed along almost the whole length of the chromosome. Because of this, chromosome rearrangements through fission and fusion are ...
Artículo
Founder events and subsequent genetic bottlenecks underlie karyotype evolution in the Ibero - North African endemic Carex helodes
(Oxford University Press, 2023-07-03)
BACKGROUND AND AIMS: Despite chromosomal evolution being one of the major drivers of diversification in plants, we do not yet have a clear view of how new chromosome rearrangements become fixed within populations, which ...
Artículo
A holocentric twist to chromosomal speciation?
(Elsevier, 2022-08)
Chromosomal rearrangements trigger speciation by acting as barriers to gene flow. However, the underlying theory was developed with monocentric chromosomes in mind. Holocentric chromosomes, lacking a centromeric region, ...
Artículo
The holocentric chromosome microevolution: From phylogeographic patterns to genomic associations with environmental gradients
(Wiley Blackwell, 2023)
Geographic isolation and chromosome evolution are two of the major drivers of diversification in eukaryotes in general, and specifically, in plants. On one hand, range shifts induced by Pleistocene glacial oscillations ...
Artículo
What drives diversification in a pantropical plant lineage with extraordinary capacity for long-distance dispersal and colonization?
(Wiley-Blackwell, 2021)
Aim: Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria ...
