Targeting histone acetylation to enhance somatic embryogenesis in Quercus suber L.

ABSTRACT: Somatic embryogenesis (SE) is an in vitro mass propagation system widely employed in plant breeding programs. However, its efficiency in many forest species remains limited due to their recalcitrance. Somatic embryogenesis relies on the induction of somatic cell reprogramming into embryogenic pathways, a process influenced by transcriptomic changes regulated, among other factors, by epigenetic modifications such as DNA methylation, histone methylation and histone acetylation. Despite its relevance, epigenetic regulation of SE in forest species is not well understood. In this study, we analyzed histone H4 acetylation during SE in cork oak (Quercus suber L.) and evaluated the effects of suberoylanilide hydroxamic acid (SAHA), a histone deacetylase (HDAC) inhibitor, scarcely used in plants, o
