ASY1 — Brassica oleracea

Summary

BoASY1, located on chromosome 6 of cabbage (Brassica oleracea), encodes a protein containing a HORMA domain and a SWIRM domain, and is annotated with protein-binding molecular function. The gene is associated with meiotic processes, including homologous chromosome pairing, homologous recombination, chiasma assembly, meiotic DNA double-strand break formation, and the progression through leptotene, zygotene, pachytene, diplotene, and metaphase. It is also linked to microtubule assembly, protein modification, and the pachytene checkpoint. Localization evidence connects the product to the nucleus, chromatin, condensed nuclear chromosomes, centromere complex, and nucleolus. Phenotypic associations include meiotic recombination, chiasma formation, crossover frequency and assurance, chromosomal stability, and chromosome axis assembly. Additionally, the gene has been linked to arsenic concentration. Studies of related genes in other species connect the family to heterosis.
