Endogenous Small RNAs and Antibacterial Resistance in Plants
Small RNAs are important regulators of developmental and physiological processes in plants as well as in animals. These small noncoding RNAs have also been demonstrated to be involved in host response against various biotic stresses. Until recently, small RNA-mediated silencing was believed to have immunity against viral infection utilizing virus-derived small RNAs. However, increasing evidence strongly associate endogenous small RNAs with regulation of plant responses to several pathogens, including bacteria. This chapter summarizes information on diversity of PAMPs, PTI, and ETI mode of plant defense response and regulatory role of endogenous small RNAs and their target genes in response to bacterial infection.
