The paper assembles and annotates the genome of a tetraploid Dahlia variabilis cultivar, identifying it as a segmental tetraploid with evidence of auto- and allopolyploidy.

The paper identifies an X-linked sex determination mechanism in cannabis and hop, showing that an X-linked gene involved in ethylene biosynthesis controls female inflorescence development, while the Y chromosome lacks clear sex-determining genes.

The paper presents a chromosome-scale, haplotype-resolved genome assembly for Quercus virginiana, contributing to genomic resources for studying hybridization and structural genomic changes in oaks.

This study investigates the genomic basis of species richness disparity in Asteraceae by analyzing genome duplications and regulatory evolution.
