Genetic diversity and IUCN Red List status

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool for conservation assessment. The IUCN uses information about a species’ range, population size, habitat quality and fragmentation levels, and trends in abundance to assess extinction risk.

Tropical forest loss and geographic location drive the functional genomic diversity of an endangered palm tree

open access: yesEvolutionary Applications, Volume 16, Issue 7, Page 1257-1273, July 2023., 2023
Abstract Human activity has diminished forests in different terrestrial ecosystems. This is well illustrated in the Brazilian Atlantic Forest, which still hosts high levels of species richness and endemism, even with only 28% of its original extent remaining. The consequences of such forest loss in remaining populations can be investigated with several

A metabarcoding protocol targeting two DNA regions to analyze root‐associated fungal communities in ferns and lycophytes

open access: yesApplications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise Detailed studies of the fungi associated with lycophytes and ferns provide crucial insights into the early evolution of land plants. However, most investigations to date have assessed fern–fungus interactions based only on visual root inspection. In the present research, we establish and evaluate a metabarcoding protocol to analyze the

Marcadores moleculares como apoyo al fitomejoramiento

open access: yesTAYACAJA, 2020
Los marcadores moleculares son secuencias de ADN que se pueden utilizar para detectar variaciones genéticas asociadas con rasgos económicamente importantes en la agricultura, de modo que pueden ser empleados por los fitomejoradores como herramientas de selección, aumentando la eficiencia del proceso tradicional, ya que se analiza el genotipo de los ...

Embracing Monogenic Parkinson's Disease: The MJFF Global Genetic PD Cohort

open access: yesMovement Disorders, Volume 38, Issue 2, Page 286-303, February 2023., 2023
Abstract Background As gene‐targeted therapies are increasingly being developed for Parkinson's disease (PD), identifying and characterizing carriers of specific genetic pathogenic variants is imperative. Only a small fraction of the estimated number of subjects with monogenic PD worldwide are currently represented in the literature and availability of
