Basal defense is present in all plants and is triggered by a general per-ception of parasite-derived general elicitors (similar to pathogen-associated molecular patterns, PAMPs) [2]. Suppression of basal defense leads to plant susceptibility parasite effectors in both basal and R gene-mediated de-fenses lead to the production of the signaling molecules such as salicylic acid (SA), jasmonic acid (JA), nitric oxide, ethylene, and various polyunsaturated fatty acids (PUFAs) [5-10]. These signaling molecules trigger cascades of sig-nal transduction pathways, leading to the launch of toxic chemical defenses and a transient reduction in primary metabolism [11]. In recent decades, rapid advances have been achieved in elucidation of molecular processes in plant defense. Numerous plant resistance genes have been cloned an
