Clones corresponding to tobacco pathogenesis-related (PR) proteins PR-4 and tomato PR protein P2 were isolated from phage cDNA libraries of tobacco infected with tobacco mosaic virus and tomato infected with Cladosporium fulvum, respectively. The probe used in these screenings was a polymerase chain reaction product, synthesized on phage DNA from the(More)
Complementary DNA clones encoding acidic and basic isoforms of tomato chitinases were isolated fromCladosporium fulvum-infected leaves. The clones were sequenced and found to encode the 30 kDa basic intracellular and the 26 and 27 kDa acidic extracellular tomato chitinases previously purified (M.H.A.J. Joostenet al., in preparation). A fourth truncated cDNA(More)
To study the possible involvement of plant hormones in the synthesis of stress proteins in tomato upon inoculation with Cladosporium fulvum, we investigated the induction of mRNAs encoding PR proteins and ethylene biosynthesis enzymes by ethephon, 2,6-dichloroisonicotinic acid (INA) and salicylic acid (SA) by northern blot analysis. Ethephon slightly(More)
The introduction of plasmid DNA into yeast by transformation or electroporation, but not by cytoduction, results in the induction of a slow growth phenotype. This phenotype is inherited as a dominant Mendelian trait, which is only exhibited in the absence of the native 2μ nuclear DNA plasmid of yeast. The use of recombinant DNA technology in yeast,(More)
