Abstract:
Plants are hubs of organismic interactions. They constantly engage in beneficial or competitive interactions with fungi, oomycetes, bacteria, insects, nematodes, and other plants. To adjust the molecular processes necessary for the establishment and maintenance of beneficial interactions and for the defense against pathogens and herbivores, plants have evolved intricate regulatory mechanisms. Besides the canonical plant immune system that acts as the primary defense, epigenetic mechanisms have started to emerge as another regulatory entity and as a target of pathogens trying to overcome the plant's defenses. In this review, we highlight recent advances in understanding the contribution of various epigenetic components and of epigenetic diversity to plant-organismic interactions.
