Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

Integrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

HGTScanner: Detecting horizontal gene transfer at the fine scale using whole organelle genomes

Methods in Ecology and Evolution, EarlyView.
Abstract Horizontal gene transfer (HGT) has profoundly shaped eukaryotic organellar genomes like plant mitochondria. Yet no generalized tools are currently available to efficiently characterize HGT across these genomes due to both high structural complexity and low sequence divergence compared to prokaryotic HGTs.

Identification and fine mapping of a major QTL for grain protein content, qGPC4D, using wheat–Aegilops tauschii introgression lines

Journal of Integrative Agriculture
Wheat is a staple cereal crop that is crucial for food security and human health. Improving wheat quality has become an essential task for allowing breeders to meet escalating market demand.

Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

Animal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Sorghum introgression breeding utilizing S. macrospermum [PDF]

, 2009
Sorghum has been improved by plant breeders for yield, biotic and abiotic stress resistance, as well as quality traits by using germplasm from within the species. Interspecific hybridization can greatly increase the amount of genetic variation available

Steady expression of high oleic acid in peanut bred by marker-assisted backcrossing for fatty acid desaturase mutant alleles and its effect on seed germination along with other seedling traits.

PLoS ONE, 2019
Peanut (Arachis hypogaea L.) is an important nutrient-rich food legume and valued for its good quality cooking oil. The fatty acid content is the major determinant of the quality of the edible oil.

Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

Cladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...

Marker-assisted introgression in backcross breeding programs [PDF]

, 1996
The efficiency of marker-assisted introgression in backcross populations derived from inbred lines was investigated by simulation. Background genotypes were simulated assuming that a genetic model of many genes of small effects in coupling phase explains

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.
