A schematic of seed priming and plant immune memory for crop disease resistance improvement. Priming of crop seeds with beneficial microbes and their derived elicitors, phytohormones and natural products, biological primimg could lead to the establishment of immune memory and induced crop disease resistance. Seed primimg with synthetic chemical inducers (chemical primimg), also could improve crop disease resistance. Physiological, transcriptional, metabolic and epigenetic changes are induced in defence priming to establish the immune memory in primed crop plants.
