CENH3 — Pisum sativum

Summary

PSAT4G160400 (CENH3, PsCENH3) on garden pea chromosome 4LG4 encodes a histone H3/CENP-A family protein with histone-fold and chromatin-binding domains, and is annotated as a structural constituent of chromatin. It is associated with kinetochore assembly, chromosome segregation, meiotic chromosome separation, centromeric silencing, and CENP-A-containing chromatin assembly. The gene product localizes to the kinetochore, centromere complex, and nucleolus. Associations include regulation of chromosome segregation, cell cycle, cell division, and double fertilization. Traits linked to this gene include relative root length, root thickness, and flowering time. Phenotypes connected to CENH3 include haploid induction, clonal reproduction, centromere function and loading, chromosome segregation, and short stature with altered leaf morphology and male sterility. Studies of related genes in other species link the family to haploid production, uniparental genome elimination, centromere identity, and flowering time.
