Bacteria (and perhaps other prokaryotic organisms), utilize a unique defense mechanism, called the restriction modification system to protect themselves from pathogens, such as bacteriophages. In this system, bacteria produce enzymes, called restriction endonucleases, that attack and destroy specific regions of the viral DNA of invading bacteriophages. Methylation of the host's own DNA marks it as "self" and prevents it from being attacked by endonucleases. Restriction endonuclea… WebMar 1, 2024 · This pathogen-induced form of resistance is known as systemic acquired resistance (SAR) ( Ross, 1961; Fu and Dong, 2013 ). SAR-induced plants display fast and intense induction of a series of defense-related genes, therefore responding more efficient and vigorous to future pathogen attacks ( Fu and Dong, 2013 ).
