1. Estudo químico de compostos de Solanum Lycopersicum com atividade antifúngica para Moniliophthora perniciosa / Chemical studies of antifungic compounds from Solanum lycopersicum against Moniliophthora perniciosa
O fungo fitopatogênico hemibiotrófico Moniliophthora perniciosa, causador da doença Vassoura-de-Bruxa no cacaueiro (Theobroma cacao), é um dos maiores responsáveis pela contribuição do declínio da produção brasileira de cacau e constitui um problema fitopatológico em todas as regiões cacauicultoras. O gênero Solanum, do qual faz parte o tomate,

2. High alpha-tomatine content in ripe fruit of Andean Lycopersicon esculentum var. cerasiforme: developmental and genetic aspects.
A variant of Lycopersion esculentum var. cerasiforme is described that deviates from the typical form of the entire species, including cultivated tomatoes, in possessing high levels (500-5000 micrograms/g of dry weight) of the steroidal alkaloid alpha-tomatine in its ripe fruits. This biotype is restricted to a tiny enclave in the valley of Río Mayo, Depart

3. Purification and characterization of tomatinase from Fusarium oxysporum f. sp. lycopersici.
The antifungal compound alpha-tomatine, present in tomato plants, has been reported to provide a preformed chemical barrier against phytopathogenic fungi. Fusarium oxysporum f. sp. lycopersici, a tomato pathogen, produces an extracellular enzyme inducible by alpha-tomatine. This enzyme, known as tomatinase, catalyzes the hydrolysis of alpha-tomatine into its
