The paper improves the amaranth genome annotation to identify causal mutations and a tissue-specific MYB transcription factor regulating betalain pathway in flowers.

This study shows gene flow from wild relatives reduced genetic load in domesticated grain amaranth and created reproductive barriers between crop species.

This study compares inbreeding depression in maize and teosinte, finding greater depression in maize due to polygenic small-effect recessive variation and reduced large-effect variants after domestication.

This study identifies a male-specific genomic region in Amaranthus palmeri, suggesting an XY sex determination system and an intermediate evolutionary state of dioecy.

The paper analyzes the genetic diversity loss in doubled-haploid lines derived from European maize landraces using SNP data, finding significant haplotype and SNP diversity reduction.

This study shows that grain amaranth was independently domesticated three times but remained incompletely domesticated due to genetic constraints.

The paper uses forward simulations to study how background selection affects genetic diversity in non-equilibrium populations over time, finding that initial dynamics often oppose long-term trends and classical models are inadequate.

This study uses simulations and machine learning to analyze how genetic architecture and selective sweeps change during polygenic adaptation to new trait optima, showing that sweeps occur even under weak selection and that demography and mutation effects are key factors.

The paper proposes the functional space hypothesis, suggesting genome size affects mutational targets and adaptation patterns in plants, but more data are needed for validation.

This study uses GBS to analyze phylogenetic relationships and genome size evolution in Amaranthus species, revealing subgenus structure and potential origins of cultivated grain amaranths.
