Write 'systemic small RNAs': read 'systemic immunity'

Research output: Contribution to journalArticleAcademicpeer-review


About 50 years ago, it was reported that pathogen-infected plants are less susceptible to a broad spectrum of the subsequent pathogen attacks. This form of induced resistance, which resembles the immunisation in mammalian cells, is called systemic acquired resistance (SAR). In the last 10 years, plant molecular biology has been revolutionised by the discovery of RNA silencing, which is also a systemic phenomenon and also contributes to plant immunity. Here, I review these two systemic phenomena in a comparative way to highlight the possibility that systemic silencing contributes to systemic immunity. This potential contribution could be in the process of gene expression reprogramming, which is needed for SAR induction, and/or in SAR signal complex, and/or in establishing SAR in remote tissues and forming priming status
