“…Part of the published studies in this field were focused on ‘basic research’; they defined the effects of particular substances contained in the selective agents in the cultures and tried to find correlations between their in vitro and in vivo effects (Behnke, 1980; Fereol, 1984; Buiatti et al., 1985; Connel et al., 1990; Hunold et al., 1992; Huang and Hartman, 1998; Jayasankar et al., 1999; Hamid and Strange, 2000; Jayasankar et al., 2000; Hollmann et al., 2002). Valuable and significant results were achieved concerning the induction of substances involved in plant pathogenesis, e.g.…”

Simultaneously with the progress in plant biotechnology since the 1980s, new methods in plant pathology have been developed. This review summarizes papers that cover basic research on the effects of selective agents on in vitro cultures of host plants, as well as applications of agents in regeneration systems that result in lines with increased variability in resistance or susceptibility. The first part of the study deals with theoretical aspects of the interactions between plants and toxin-producing pathogens, mode of phytotoxic action, and host-and non-host-selective toxins. The second part lists and describes various agents used for selections in vitro. In the last two decades more than 100 publications focused on these selections for the improvement of resistance to plant pathogens. Over 30 plant species were examined to utilise various selection agents extracted from about 40 plant pathogens. The review covers basic research studies and methods that elucidate the relationships between in vitro and in vivo mechanisms of resistance, but also try to develop practical applications to obtain resistant breeding lines. Such methods often utilise some type of explant cultures of the host plants that are treated with various selective agents (culture filtrates, toxins, elicitors), which then elicit typical reactions that parallel those by the pathogens. Their application successfully resulted in resistant lines in banana, carnation, grapevine, strawberry and wheat. Nowadays, these techniques are an important complement to classical breeding methods.
