Histones are abundant cellular proteins but, if not incorporated into chromatin, they are usually bound by histone chaperones. Here, we identify Arabidopsis NASP as a chaperone for histones H3.1 and H3.3. NASP interacts in vitro with monomeric H3.1 and H3.3 as well as with histone H3.1-H4 and H3.3-H4 dimers. However, NASP does not bind to monomeric H4. NASP shifts the equilibrium between histone dimers and tetramers towards tetramers but does not interact with tetramers in vitro. Arabidopsis NASP promotes [H3-H4]
