Research using Xenopus takes advantage of large, abundant eggs and readily manipulated
embryos in addition to conserved cellular, developmental and genomic organization with …

Amphibians are a clade of over 8,400 species that provide unique research opportunities
and challenges. With amphibians undergoing severe global declines, we posit that …

The development of efficient sequencing techniques has resulted in large numbers of
genomes being available for evolutionary studies. However, only one genome is available …

Identifying homology between sex chromosomes of different species is essential to
understanding the evolution of sex determination. Here, we show that the identity of a …

Animal interphase chromosomes are organized into topologically associating domains
(TADs). How TADs are formed is not fully understood. Here, we combined high-throughput …

The Xenopus embryo has provided key insights into fate specification, the cell cycle, and
other fundamental developmental and cellular processes, yet a comprehensive …

The B7 family of genes is essential in the regulation of the adaptive immune system. Most B7
family members contain both variable (V)-and constant (C)-type domains of the …

Homomorphic sex chromosomes and rapid turnover of sex-determining genes can
complicate establishing the sex chromosome system operating in a given species. This …

Abstract The Western clawed frog Xenopus tropicalis is a diploid model system for both frog
genetics and developmental biology, complementary to the paleotetraploid X. laevis. Here …

Abstract Background Cultivated peanut (Arachis hypogaea) is an allotetraploid species
whose ancestral genomes are most likely derived from the A-genome species, A …
