Photo of cell death caused by Nep1
Dr. Bailey has developed considerable expertise in methods for studying plant defense mechanisms and plant pathogen interactions and has initiated new areas of research associated with microbial proteins that elicit plant cell death. Dr. Bailey discovered that a 22-kDa xylanase (EIX) from the biocontrol agent Trichoderma viridecould induce defense responses in tobacco. The responses to EIX include rapid necrosis (Bailey et al. 1992a), changes in membrane permeability (Bailey et al., 1992a, Bailey et al., 1993), and glycosylation and fatty acylation of phytosterols (Moreau et al., 1994). EIX was transported throughout a plant by the vascular system (Sharon et al., 1992). Dr. Bailey cloned an EIX induced ACC synthase from tobacco (Bailey et al., 1992b) that was used to prove that ACC synthase transcript accumulated in EIX treated tissues in a time course corresponding to ethylene production (Avni et al., 1994).
Dr. Bailey identified, isolated, and characterized a protein (Nep1) from Fusarium oxysporumf. sp. erythroxylithat causes necrosis and induces ethylene in coca leaves (Bailey, 1995). The gene for Nep1 was cloned allowing for genetic manipulation in F. oxysporumand other plant pathogens (Nelson et al., 1998). Nep1 has been disrupted and over expressed in F oxysporum f. sp. erythroxyli without influencing pathogenicity (Bailey et al., In Press). Dr. Bailey discovered the herbicidal potential of the fungal protein Nep1 against many dicot weed species (Jennings et al. 2000). Subsequent work by Dr. Bailey demonstrated that Nep1 is compatible with biological (Bailey et al., 2000b; Bailey et al., 2000c) and chemical herbicides.
Dr. Bailey carried out laboratory and field experiments resulting in development of a biocontrol strategy for the narcotic plant Erythroxylum cocausing the plant pathogenic fungus F. oxysporum. Dr. Bailey characterized aspects of the ecology and biology of infestation and spread of F. oxysporumf. sp. erythroxyliin the field and greenhouse (Bailey et al., 1998). Dr. Bailey directed studies of a natural epiphytotic of coca wilt in the Huallaga Valley of Peru (Nelson et al., 1997). Two pathogenic genotypes were identified based on RAPD patterns and vegetative compatibility groups. Dr. Bailey subsequently carried out the field, greenhouse and laboratory studies assessing the bioherbicidal potential of Pleospora papaveraceaand Dendryphion penicillatumon opium poppy (Bailey et al., 2000a). Dr. Bailey characterized environmental parameters (time, temperature and moisture) required for poppy infection by P. papaveraceaand D. penicillatumconidia. This work produced the first SEM photographs of the infection processes of conidia of these fungi.
Dr. Bailey is now characterizing the molecular responses of Theobroma cacaoto biotic and abiotic stresses. Theobroma cacao, the source of chocolate, is considered an alternative crop to the narcotic crop coca. Dr. Bailey has developed a program accessing the responses of Theobroma cacaoto inducers of plant defense, endophytes, and plant pathogens. This work is ongoing and has already resulted in the identification of over 300 potential stress response genes in cacao. In addition, many basic aspects of the interactions between Theobroma cacaoand microbes have been described. Multiple cooperative agreements have been arranged with both State and International laboratories preparing a foundation for future research.
