The role of non-additive gene action on gene expression variation in plant domestication

EvoDevo, 2023
Background Plant domestication is a remarkable example of rapid phenotypic transformation of polygenic traits, such as organ size. Evidence from a handful of study cases suggests this transformation is due to gene regulatory changes that result in non ...

Unearthing soil arthropod diversity through DNA metabarcoding [PDF]

PeerJ, 2022
DNA metabarcoding has the potential to greatly advance understanding of soil biodiversity, but this approach has seen limited application for the most abundant and species-rich group of soil fauna–the arthropods.

Adaptive and non-adaptive divergence in a common landscape

Nature Communications, 2017
The three-spined stickleback is a model species for the study of adaptive divergence. Here, Raeymaekers et al. compare how the three-spined stickleback and its relative the nine-spined stickleback vary at the phenotypic and genomic levels in response to ...

LANDMark: an ensemble approach to the supervised selection of biomarkers in high-throughput sequencing data

BMC Bioinformatics, 2022
Background Identification of biomarkers, which are measurable characteristics of biological datasets, can be challenging. Although amplicon sequence variants (ASVs) can be considered potential biomarkers, identifying important ASVs in high-throughput ...

Type Genomics: A Framework for Integrating Genomic Data into Biodiversity and Taxonomic Research. [PDF]

Syst Biol
Abstract Name-bearing type specimens have a fundamental role in characterizing biodiversity, as these objects represent the physical link between a scientific name and the biological organism. Type specimens are usually deposited in natural history collections, which provide key infrastructure for research on essential biological ...

Comparative transcriptome analysis suggests convergent evolution of desiccation tolerance in Selaginella species

BMC Plant Biology, 2020
Background Desiccation tolerant Selaginella species evolved to survive extreme environmental conditions. Studies to determine the mechanisms involved in the acquisition of desiccation tolerance (DT) have focused on only a few Selaginella species.

Evaluating the effect of reference genome divergence on the analysis of empirical RADseq datasets

Ecology and Evolution, 2020
The advent of high‐throughput sequencing (HTS) has made genomic‐level analyses feasible for nonmodel organisms. A critical step of many HTS pipelines involves aligning reads to a reference genome to identify variants.

Multi-marker metabarcoding resolves subtle variations in freshwater condition: Bioindicators, ecological traits, and trophic interactions

Ecological Indicators, 2022
Freshwater systems are experiencing rapid biodiversity losses resulting from high rates of habitat degradation. Ecological condition is typically determined through identifying either macroinvertebrate or diatom bioindicator assemblages and comparing ...
