Phylogenomics resolves key relationships in Rumex and uncovers a dynamic history of independently evolving sex chromosomes

M. S. Hibbins, J. L. Rifkin, B. I. Choudhury, O. Voznesenka, B. M. Sacchi, M. Yuan, Y. Gong, S. C. H. Barrett, S. I. Wright

This study uses phylogenomic analysis of Rumex species to resolve sex chromosome evolution, finding two independent origins and chromosomal rearrangements without adaptive expansion support.

Genomic signatures of hybridization on the neo-X chromosome of Rumex hastatulus

F. E. G. Beaudry, J. L. Rifkin, A. L. Peake, D. Kim, M. Jarvis-Cross, S. C. Barrett, S. I. Wright

The paper examines gene flow and reproductive isolation in Rumex hastatulus hybrid zones, finding that the neo-X chromosome contributes to inter-cytotype differentiation.

GENETIC ARCHITECTURE OF DIVERGENCE: THE SELFING SYNDROME IN IPOMOEA LACUNOSA

J. L. Rifkin, G. Cao, M. D. Rausher

This study investigates the genetic architecture of the selfing syndrome in Ipomoea lacunosa by analyzing phenotypic correlations and QTL overlaps in F2 offspring, finding that traits cluster into modules with strong within-module correlations.

Morning glory species co-occurrence is associated with asymmetrically decreased and cascading reproductive isolation

K. L. Ostevik, J. L. Rifkin, H. Xia, M. D. Rausher

The paper investigates how asymmetric gene flow between morning glory species affects reproductive barrier strength, finding that introgression decreases barriers in the recipient species and impacts within-species compatibility.

Widespread Recombination Suppression Facilitates Plant Sex Chromosome Evolution

J. L. Rifkin, F. L. Beaudry, Z. Humphries, B. I. Choudhury, S. C. H. Barrett, S. I. Wright

The paper investigates recombination suppression in a plant species with a young neo-sex chromosome, finding that low recombination rates preceded sex linkage.
