Dissecting the regulatory and genomic drivers of the dichogamy determining G-locus in pecan

The paper identifies the genetic drivers of the G-locus in pecan trees using pangenome-integrated quantitative genomics, revealing a Mendelian super-gene responsible for dichogamy.

Leveraging species-wide variation and patterns of adaptation to inform pecan crop improvement efforts

This study uses over 700 pecan genotypes and a haplotype-resolved genome to identify gene pools, assess environmental adaptation, and predict future maladaptation risks.

The origins and adaptive consequences of polyploidy in a dominant prairie grass

This study investigates the origins and adaptive consequences of polyploidy in the prairie grass Andropogon gerardi, finding that whole genome duplication is common and provides fitness advantages in xeric climates.

ZW sex chromosome structure in Amborella trichopoda

The paper presents a haplotype-resolved genome assembly of Amborella trichopoda, identifying a young ZW sex chromosome system with a 3-Megabase sex-determination region that shows limited degeneration.

Allopolyploidy expanded gene content but not pangenomic variation in the hexaploid oilseed Camelina sativa

The paper sequenced twelve Camelina sativa genomes to study pangenomic variation in an allohexaploid species, finding minimal gene presence-absence variation but subgenome-specific gene content.

The somatic genetic and epigenetic mutation rate in a wild long-lived perennial Populus trichocarpa

The paper quantifies age-related somatic mutations and epimutations in a wild Populus trichocarpa tree over 330 years, showing lower mutation rates than annuals and distinct epimutation origins.
