“…Histone modification is a reversible method that cells use to control gene expression, with histone acetylation activating expression of specific sets of genes (reviewed in Lauria and Rossi, 2011). Histone modifications, including acetylation and deacetylation, are involved in controlling a wide variety of pathways ranging from hormone, stress, and light responses to mitosis, development, and Agrobacterium-mediated transformation (Xu et al, 2005; Chen et al, 2010; Desvoyes et al, 2010; Servet et al, 2010; Berr et al, 2011; Costas et al, 2011; Grafi, 2011; Magori and Citovsky, 2011; Qiao and Fan, 2011; Yaish et al, 2011; Luo et al, 2012). Of particular interest to this work are previous findings indicating a role for histone acetylation in sugar response.…”
