ENHANCED DISEASE RESISTANCE1  ( EDR1 ) encodes a  Raf -like mitogen-activated protein kinase, and it acts as a negative regulator of disease resistance and ethylene-induced senescence. Mutations in the  EDR1  gene can enhance resistance to powdery mildew both in monocotyledonous and dicotyledonous plants. However, little is known about  EDR1 -like gene members from a genome-wide perspective in plants. In this study, the tobacco  (Nicotiana tabacum)   EDR1 -like gene family was first systematically analyzed. We identified 19  EDR1 -like genes in tobacco, and compared them to those from Arabidopsis, tomato and rice. Phylogenetic analyses divided the  EDR1 -like gene family into six clades, among them monocot and dicot plants were respectively divided into two sub-clades.  NtEDR1-1A  and  NtEDR1-1B  were classified into clade I in which the other members have been reported to negatively regulate plant resistance to powdery mildew. The expression patterns of tobacco  EDR1 -like genes were analyzed after plants were challenged by  Golovinomyces orontii , and showed that several other  EDR1 -like genes were induced after infection, as well as  NtEDR1-1A  and  NtEDR1-1B . Expression analysis showed that  NtEDR1-13  and  NtEDR1-16  had exclusively abundant expression patterns in roots and leaves, respectively, and the remaining  NtEDR1 -like members were actively expressed in most of the tissue/organ samples investigated. Our findings will contribute to further study of the physiological functions of  EDR1 -like genes in tobacco.
