Epigenomic reprogramming in plant regeneration: Locate before you modify
Current opinion in plant biology(2023)
摘要
Plants possess remarkable abilities for regeneration, and this developmental capability is strongly influenced by environmental conditions. Previous research has highlighted the positive effects of wound signaling and warm temperature on plant regeneration, and recent studies suggest that light and nutrient signals also influence the regenerative efficiencies. Several epigenetic factors, such as histone acetyl-transferases H2A variants, play crucial roles in regulating the expression of genes implicated in plant regeneration. However, how these epigenetic factors recognize specific genomic regions to regulate regeneration genes is still unclear. In this article, we describe the latest studies of epigenetic regulation and discuss the functional coordination between transcription factors and epigenetic modifiers in plant regeneration.
