Using herbarium collections to study genetic responses to global change

New Phytologist, EarlyView.
Summary Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have made the extraction of genetic data from these preserved specimens increasingly feasible, enabling new insights into plant biodiversity and ...

Fine-Scale Resolution of Runs of Homozygosity Reveal Patterns of Inbreeding and Substantial Overlap with Recessive Disease Genotypes in Domestic Dogs

G3: Genes, Genomes, Genetics, 2019
Inbreeding leaves distinct genomic traces, most notably long genomic tracts that are identical by descent and completely homozygous. These runs of homozygosity (ROH) can contribute to inbreeding depression if they contain deleterious variants that are ...

Population genomic signatures of founding events in autonomously self‐fertilizing plants: a test with Impatiens capensis

New Phytologist, EarlyView.
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

ClAPRT3‐Mediated Adenine Salvage Pathway Enhances Purine Metabolites to Sustain Seed Vigour During Selfing in Cunninghamia lanceolata

Plant Biotechnology Journal, EarlyView.
ABSTRACT Selfing often causes inbreeding depression, especially during seed and seedling stages. However, some selfed progeny show low inbreeding depression with enhanced vigour, differing from inbred counterparts. This study investigates the molecular mechanisms maintaining seed vigour during selfing in Cunninghamia lanceolata.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Effects of allele frequency estimation on genomic predictions and inbreeding coefficients.

, 2008
Genetic calculations often require estimating allele frequencies, which differ across time due to selection and drift. Data were 50,000 simulated markers and 39,985 actual markers for 2391 genotyped Holstein bulls. Gene content of relatives and gene frequencies in the base (founder) population were estimated using pedigrees and a linear model ...

Genotypic Variation and Association Mapping for Plant Stature and Anthesis‐Silking Interval in Set of Temperate‐Adapted Maize Lines Developed by DH and SSD Methods

Plant Breeding, EarlyView.
ABSTRACT BS39 is a broad‐based population of tropical maize adapted to temperate environments that can provide useful and unique alleles to US Corn Belt breeding programmes. Doubled‐haploid (DH) has been used as an efficient alternative method to speed up the development of maize lines. Our objectives were to compare genetic parameters for plant height

Genetic diversity in taro (Colocasia esculenta (L.) Schott) accessions using agro‐morphological traits and DArT SNP

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Taro (Colocasia esculenta (L.) Schott) is one of the neglected root crops with great potential for ensuring food security. Nigerian taro genetic diversity has been rarely reported, particularly using single‐nucleotide polymorphism (SNP) markers.
