This study compares gene expression and network architecture in diploid, synthetic, and natural autotetraploid Arabidopsis arenosa under stress, showing synthetic tetraploids have higher expression variation and network plasticity.

The paper presents a genomic resource with 1018 A. lyrata and 736 A. arenosa genomes, enabling studies of adaptation and genetic diversity through a searchable database and GWAS analysis of latitudinal clines.

This study compares genomic adaptation in diploid and autotetraploid Arabidopsis arenosa populations, finding that tetraploids retain more genetic variation and use it to compensate for selection constraints.

This study identifies convergent genetic adaptations to serpentine soil in two Alyssum species and compares them to Arabidopsis arenosa to find shared pathways.
