CENH3 — Beta vulgaris subsp. vulgaris

Summary

BvCENH3 (BVRB_4G094950) on sugar beet chromosome Bvchr4_un.sca015 encodes a histone H3/CENP-A family protein with structural constituent of chromatin and DNA-binding activities. The gene is associated with regulation of chromosome segregation, centromeric silencing, kinetochore assembly, meiotic chromosome separation, CENP-A containing chromatin assembly, meiotic cell cycle, mitosis, chromatin silencing, and chromosome division. It is also associated with hormone metabolism, auxin anabolism, auxin transport, embryogenesis, and double fertilization. Localization evidence links the product to the nucleus, nucleolus, kinetochore, chromocenter, plastid, and chromatin. Associations with root length, root thickness, and flowering time have been observed. The gene is linked to haploid induction, genome elimination, clonal reproduction, fertility, centromere function, centromere formation, centromere loading, centromere localization, chromosome segregation, kinetochore function, and centromere DNA methylation. Studies of related genes in other species connect the family to centromere identity, haploid production, uniparental genome elimination, meiotic genome stability, and flowering time.
