CENH3 — Pisum sativum

Summary

PSAT5G090120 (CENH3, PsCENH3) on chromosome 5LG3 encodes a histone H3/CENP-A family protein with histone-fold and chromatin-binding domains, and is annotated with structural constituent of chromatin, DNA binding, histone binding, and methylated DNA binding activities. This gene is associated with kinetochore assembly, chromosome segregation, centromeric silencing, meiotic chromosome separation, and CENP-A-containing chromatin assembly. It localizes to the kinetochore, centromere complex, chromocenter, and nucleolus. Associations include relative root length, root thickness, flowering time, DNA methylation, centromere hypomethylation, haploid induction, clonal reproduction, 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, fertility, plant growth, and flowering time.
