Agriculture around the world faces a myriad of problems: Pests, weeds, random and extreme weather, and drought, to name a few. While none of these issues are new, because of climate change in particular, several of them are being exacerbated. Techniques like genetic engineering, artificial selection, and mutagenesis have made great strides in producing crops with novel or enhanced genes that can tackle these issues.
But modifying genomes and focusing on the identity of genes can’t be the only solution, a multifaceted approach is needed to handling these issues. One idea that has been investigated by crop scientists is modifying a gene’s behavior through altering a plant’s epigenome. The idea is still in its infancy and faces many challenges, but experts believe epigenetic modified organisms (EPOs) may hold a great deal of promise for offering solutions to these agricultural problems.....
