“…This hypothesis is supported by numerous findings that the presence of PRs and the state of acquired resistance are closely linked (21,27,43). Like the induction of PRs, acquired resistance is nonspecific as to both the inducing and the challenging pathogen, localized infection by one pathogen (virus, fungus, or bacterium) usually affording at least partial protection against both the same and other pathogens that induce similar symptoms.…”

“…Their accumulation in the intercellular spaces together with the fact that PR-bt protein is synthesized as a precursor with a signal sequence of 30 amino acids, which is probably cleaved off during maturation (Bol, 1988), support the hypothesis that they may act as intercellular 'messengers' (Hooft van Huijsduijnen et al, 1985;Matsuoka et al, 1987) in induced resistance phenomena (Gianinazzi, 1982). …”

“…Furthermore the nature und localizittion (plas-malemma, cytoplasm, nucleus) of the receptor site for gene activation by different inducers is not known. Gianinazzi (1984) has proposed that chemicals like PAA and SA simulate, at the cellular level, the mobile compound produced after a hypersensitive reaction and responsible for inducing non-sjjecific resistance in plants after virus infection (Ross, 1961;Gianinazzi, 1982;Kuc, 1982;Gianinazzi & Ahl, 1983). Some links seem to exist between the genetic determinants of non-specific and specific resistance and their products may act through the same gene; the synergistic effect normally observed between specific and non-specific resistance, and the presence of PRb-proteins in both, supports this hypothesis.…”
