"Fuzzy specificity" shapes diazotroph diversity and composition in nodulating plants of the Southeastern USA

The paper examines diazotroph diversity in nodulating plants across the southeastern USA, finding host phylogeny strongly shapes symbiont composition and diversity.

Multidomain triple target capture for navigating complex symbioses

This paper develops a target capture strategy to improve metagenomic characterization of eukaryotic ribosomal DNA and root nodule symbiosis genes, showing higher recovery and detection of low-abundance taxa compared to amplicon sequencing.

Phosphorus-laden Mg/Fe Layered Double Hydroxide Dispersed on Douglas fir Biochar as a Controlled Release Fertilizer and its effect on the growth of bush beans (Phaseolus vulgaris).

This study evaluates a phosphorus-loaded Mg/Fe layered double hydroxide on Douglas fir biochar as a controlled-release fertilizer, showing improved bush bean growth and nutrient uptake compared to conventional fertilizers.

SPECIES DELIMITATION IN AN INTRACTABLE SYNGAMEON: BRINGING ORDER TO THE POLYPHYLETIC HEUCHERA AMERICANA GROUP

The paper reassesses species limits in a syngameon of Heuchera, identifying five species and three varieties using genetic and phenotypic data.

THE GEOGRAPHIC STRUCTRUE OF CHLOROPLAST CAPTURE IN A HYBRID ZONE

The paper examines chloroplast capture in Heuchera hybrids, finding multiple independent events rather than a single ancestral one, and links Pleistocene climate dynamics to hybridization patterns.

Investigating the landscape of plant-pollinator interactions in a hybrid zone

The paper investigates how floral volatile organic compounds and pollinator interactions influence hybridization rates in the Heuchera genus, finding that shared attractants and pollinators correlate with higher hybridization.
