The copia-like Tnt1 element of tobacco is one of the few active plant retrotransposons and is transcriptionally activated, in tobacco and in heterologous species, by biotic and abiotic stress factors. In order to establish more precisely the link between Tnt1 activation and plant defense responses, the expression of the Tnt1 promoter was studied in a gene-for-gene pathosystem, the interaction between tomato and the fungal pathogen Cladosporium fulvum. In compatible interactions, Tnt1 expression is highly induced throughout the leaf regions colonized by the fungus, while in incompatible interactions Tnt1 induction is transient and localized in distinct foci. Tnt1 expression after fungal inoculation parallels the differential activation of tomato defense genes. Tnt1 expression is induced by nonspecific factors of plant or fungal origin present in apoplastic fluids of leaf tissues infected by virulent races of C. fulvum, but is also activated by specific factors resulting from the interaction between fungal avirulence peptides and plant resistance genes. Tnt1 activation by apoplastic fluids containing avirulence peptides of C. fulvum is detected soon after elicitation. These results demonstrate that Tnt1 transcriptional activation correlates with biological responses of tomato to infection by C. fulvum and is mediated through signals originating from both race-specific and non-race-specific perception pathways.

A study was made of the carbon and nitrogen nutrition of races 7, 8, and 10 of Cladosporium fulvum, and an attempt was made to relate the findings to the differential pathogenicity of the races.Cysteine was found to exert a differential effect on the growth of two races of the pathogen. Race 1 was stimulated by concentrations inhibitory to race 6. C. fulvum was found to have a partial deficiency for thiamine. The sporulation of race 10 on susceptible tomato plants was heavier with alanine-grown cultures than with any other nutritional treatment. Altering the nitrogen nutrition of varieties Potentate (S) and V-121 (R) did not affect their differential reactions to race 1. A reduction in nitrogen feeding to Stirling Castle (R) increased its resistance to race 1.A chromatographic study was made of the changes in amino compounds and sugars in Potentate and V-121 after infection by races 1 and 6. The relation of the findings to the resistance of V-121 to race 1 is discussed.The resistance of Stirling Castle was investigated by comparing the amino compounds and sugars in leaves of healthy plants and plants infected by race 1 under optimal conditions and under reduced light, where the resistance breaks down. Chromatographic analyses showed a noticeable depletion of certain metabolites in plants infected under reduced light as compared with the amount of depletion, if any, in the controls.

Different Origins

In order to investigate cross-protection mechanisms between stresses of different origins, greenhouse experiments were conducted to determine whether resistance levels to the fungal pathogen P. capsici were affected on wounded plants. To this purpose, tomato roots were wounded at 24h-intervals and allowed to age for up to 7 days before inoculation. Data from preliminary experiments indicate first (0–48 h old wounds) an increase in disease severity in wounded as compared to unwounded tomato plants infected with P. capsici. Then, as the wounds age, disease severity decreases to the point that plants wounded 3 days before inoculation are less susceptible than nonwounded plants. Here, with the use of tomato mutant lines, we suggest the involvement of ethylene (C<sub>2</sub>H<sub>4</sub>) and jasmonates (Ja) in the development of these responses towards P. capsici upon wounding of tomato plants.
