A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Uncoordinated centrosome cycle underlies the instability of non-diploid somatic cells in mammals

Journal of Cell Biology, 2018
In animals, somatic cells are usually diploid and are unstable when haploid for unknown reasons. In this study, by comparing isogenic human cell lines with different ploidies, we found frequent centrosome loss specifically in the haploid state, which ...

Population genomics reveals evolution and variation of Saccharomyces cerevisiae in the human and insects gut [PDF]

, 2019
The quest to discover the variety of ecological niches inhabited by Saccharomyces cerevisiae has led to research in areas as diverse as wineries, oak trees, and insect guts.

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Next-generation transcriptome assembly and analysis: impact of ploidy.

Methods, 2020
Whole genome duplications (WGD) occur widely in plants, but the effects of these events impact all branches of life. WGD events have major evolutionary impacts, often leading to major structural changes within the chromosomes and massive changes in gene ...

Pathways to polyploidy : indications of a female triploid bridge in the alpine species Ranunculus kuepferi (Ranunculaceae) [PDF]

, 2017
Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring (triploid bridge), or with other ...

Development and application of KASP assays to differentiate between Sorghum bicolor, halepense, and their hybrids

Pest Management Science, EarlyView.
A panel showing the morphological differences between Sorghum halepense (A), hybrids (B), and Sorghum bicolor (C) with a novel KASP‐based genetic assay capable of reliably distinguishing between them. Partially Created in BioRender. https://BioRender.com/1u30ukv Abstract BACKGROUND Sorghum bicolor and Sorghum halepense can readily hybridize, creating ...

Genome size variation and polyploidy incidence in the alpine flora from Spain

Anales del Jardín Botánico de Madrid, 2013
The interest to study genome evolution, in particular genome size variation and polyploid incidence, has increased in recent years. Still, only a few studies have been focused at a community level.

The effect of radiation on the long term productivity of a plant based CELSS [PDF]

Mutations occur at a higher rate in space than under terrestrial conditions, primarily due to an increase in radiation levels. These mutations may effect the productivity of plants found in a controlled ecological life support system (CELSS).
