CENH3 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0070000, designated CENH3 on barley chromosome 1H, encodes a centromeric histone H3 variant (CENP-A family) that is a structural constituent of chromatin and binds nucleosomal DNA. The gene is associated with kinetochore assembly, chromosome segregation, sister chromatid cohesion, and both mitosis and meiosis. It is linked to seed development, chromatin silencing, and DNA condensation. Localisation evidence places the product at the kinetochore, nucleolus, and nucleus. Studies of related genes in other species connect the CENH3 family to spike density and awn length, though these traits are not established for barley.
