However, the functional relationship between H2A and its variants in plants remains largely obscure. Using CRISPR-Cas9 editing, we generated a mutant lacking four H2A isoforms in Arabidopsis and analyzed the functional and structural relationships between H2A, H2A.Z, and H2A.W. RNA sequencing and phenotype analyses revealed mild changes in gene transcription and plant development in mutants lacking H2A, H2A.Z, or H2A.W compared with the wild-type plants. Chromatin immunoprecipitation sequencing analysis showed that H2A can substitute for both H2A.Z and H2A.W across the genome, including in euchromatin and heterochromatin regions. However, H2A.Z replaced both H2A and H2A.W primarily within the euchromatin regions. By using DNA and histones from Arabidopsis, we constructed nucleosomes containing H2A, H2A.Z, or H2A.W and resolved their cryogenic electron microscopy (cryo-EM) structures at near-atomic resolution. Collectively, the results reveal the structural similarity and functional redundancy of H2A and its variants in Arabidopsis. | |||||||||
