Genomic prediction and estimation of marker interaction effects

The paper extends a genomic prediction method to include marker interaction effects, showing small improvements in predictions using Arabidopsis thaliana data.

A Genome-Wide Association Analysis Reveals Epistatic Cancellation of Additive Genetic Variance for Root Length in Arabidopsis thaliana

This paper identifies epistatic genetic interactions underlying root length variation in Arabidopsis thaliana, revealing that epistasis cancels additive genetic variance, and discovers functional candidate genes.

The "Gini index" in genetics: measuring genetic architecture complexity of quantitative traits

The paper introduces a genetic architecture score inspired by the Gini index to quantify the complexity of genetic architecture in quantitative traits and validates its effectiveness through simulations.

Flaw or discovery? Calculating exact p-values for genome-wide association studies in inbred populations

The paper calculates exact p-values for genome-wide association studies in inbred populations, showing improved detection power and reduced inflation compared to standard methods.

Natural CMT2 variation is associated with genome-wide methylation changes and temperature seasonality

The paper identifies CMT2 genetic variation linked to methylation changes and temperature adaptation in Arabidopsis thaliana using a novel genome-wide association method.
