is an amphicarpic plant in the Brassicaceae family. Plants develop two fruit types, one above and another below ground. This rare trait is associated with octoploidy in . The absence of genomic data for currently limits our understanding of the development and evolution of amphicarpy. Here, we produced a chromosome-scale assembly of the genome using high-fidelity long read sequencing with the Pacific Biosciences platform. We assembled 32 chromosomes and two organelle genomes with a total length of 597.2 Mb and an N50 of 18.8 Mb. Genome completeness was estimated at 99.8%. We observed structural variation among homeologous chromosomes, suggesting that originated via allopolyploidy, and phased the octoploid genome into four sub-genomes using orthogroup trees. This fully phased, chromosome-level genome assembly is an important resource to help investigate amphicarpy in and the origin of trait novelties by allopolyploidy.

Arthrogryposis multiplex congenita (AMC) is a heterogeneous disorder associated with 1/3000 to 1/5000 live births. We report a consanguineous family with multiple affected members with AMC and identified a recessive mutation in the highly conserved splice donor site, resulting in the mis-splicing of the affected exons. SENP7 is a deSUMOylase that is critical for sarcomere assembly and skeletal muscle contraction by regulating the transcriptional program in the skeletal muscle.

Objectives: Toona sinensis, commonly known as Chinese toon, is a perennial woody plant with significant economic and ecological importance. This study employed whole-genome resequencing of 180 T. sinensis samples collected from Shandong to analyze genetic variation and diversity, ultimately identifying 18,231 high-quality SNPs after rigorous quality control and linkage disequilibrium pruning.

Background: Tea-oil Camellia within the genus Camellia is renowned for its premium Camellia oil, often described as "Oriental olive oil". So far, only one partial mitochondrial genomes of Tea-oil Camellia have been published (no main Tea-oil Camellia cultivars), and comparative mitochondrial genomic studies of Camellia remain limited.
Results: In this study, we first reconstructed the entire mitochondrial genome of C.
