Experimental studies on plants provide some of the best-known examples of epigenetic variants that are inherited across multiple generations . However, it is still unclear to what extent transgenerational epigenetic inheritance occurs in plants in nature. WebMay 25, 2011 · For example, recent studies showed that several enzymes that modify DNA or histone proteins are essential elements of signaling pathways, allowing proper neuronal signaling for learning and memory. 9 This is because the formation of long-term memory requires that epigenetic processes induce lasting changes in gene expression in brain …
