Low genetic diversity and intrapopulation spatial genetic structure of the Atlantic Forest tree, Esenbeckia leiocarpa Engl. (Rutaceae)

Annals of Forest Research, 2014
Studies on population genetics are the key to designing effective in situ management plans for tree species, in particular, those subjected to pressure from anthropogenic processes, such as forest fragmentation and logging.

Inference of Selection from Genetic Time Series Using Various Parametric Approximations to the Wright-Fisher Model

G3: Genes, Genomes, Genetics, 2019
Detecting genomic regions under selection is an important objective of population genetics. Typical analyses for this goal are based on exploiting genetic diversity patterns in present time data but rapid advances in DNA sequencing have increased the ...

A theory of evolutionary dynamics on any complex population structure reveals stem cell niche architecture as a spatial suppressor of selection

Nature Communications
How the spatial arrangement of a population shapes its evolutionary dynamics has been of long-standing interest in population genetics. Most previous studies assume a small number of demes or symmetrical structures that, most often, act as well-mixed ...

Whole genome resequencing reveals the correlation between selection signatures and adaptability of Micropterus salmoides to artificial fed

Scientific Reports
Largemouth bass (Micropterus salmoides, LMB) is an important aquaculture species due to its excellent flesh quality and environmental adaptability. It has been continuously introduced to many countries and cultured for decades.

Genotyping-by-sequencing of Illicium difengpi highlights its potential genetic diversity and conservation status

Scientific Reports
Illicium difengpi is a critically endangered plant endemic to the karst mountains of Guangxi, China. Because of its medicinal and ecological values, many efforts were made on assessing the medicinal usage, natural history, ex-situ conservation, and ...

Deciphering the genetic basis of biological nitrogen fixation in peanut (Arachis hypogaea L.) using an interspecific QTL-mapping population

Peanut (Arachis hypogaea L.) is an allotetraploid grain legume crop cultivated in Africa mainly by poor farmers, in nitrogen (N) and phosphorus (P) depleted soils and in low intensification systems. Improving biological nitrogen fixation (BNF) in peanut could be of great interest to increase yield and lift-up soil fertility.
