| Research Abstract |
Mitogen-activated protein kinases (MAPKs) are signal factors that exist ubiquitously in eukaryotes. To define the exact roles of WIPK and SIPK, tobacco MAPKs, in tobacco mosaic virus (TMV) resistance, we analyzed transgenic tobacco plants in which WIPK and SIPK were silenced. Resistance to TMV was suppressed in these silenced plants, suggesting that WIPK and SIPK negatively regulate resistance to TMV, a result different from that previously shown.
