The paper analyzes gene tree topology space in the plant genus Glycine, finding a flat distribution of topologies with no clear peak at the species tree, suggesting complex historical signals from introgression and polyploidy.

nQuack predicts ploidy from sequence data using site-based heterozygosity, improving upon existing methods with model selection and simulation.

This study reports high-quality genome sequences of C. maxima and C. moschata, revealing an allotetraploidization event and long-term karyotype stability in Cucurbita genomes.
