ASY1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0494140 (HvASY1) encodes a HORMA domain-containing protein. The gene is associated with meiotic prophase I, including homologous chromosome pairing, chiasma assembly, and the pachytene checkpoint, as well as megasporogenesis and microsporogenesis. It localises to the nucleus, chromatin, and condensed nuclear chromosome. HvASY1 is linked to meiotic recombination, crossover frequency, crossover assurance, crossover interference, chiasma formation, chromosome axis assembly, and chromosomal and genomic stability. Phenotypic associations include meiotic and reproductive traits, pollen development, and vegetative growth. The gene is also connected to arsenic concentration. Studies of related genes in other species link the HORMA domain family to anthesis time and disease susceptibility.
