Detecção simultânea de fatores de resistência à murcha de fusário do tomateiro por meio de PCR multiplex

Abstract: Resumo: O objetivo deste trabalho foi elaborar e validar um protocolo de detecção simultânea, via reação em cadeia da polimerase multiplex (PCR multiplex), de regiões genômicas do tomateiro (Solanum lycopersicum) associadas a fatores de resistência às três raças fisiológicas de Fusarium oxysporum f. sp. lycopersici (FOL). Os pares de iniciadores empregados foram SSR-67 (específico para o gene I-1), TFusrr (específico para o gene I-2) e SSRD (específico para o gene I-3). Os resultados de genotipagem com marcado… Show more

“…From the 15 cultivars studied and reported as resistant to race 2 (table 2), only seven displayed an incompatible reaction to race 2, including Serato F 1 cultivar. These same cultivars showed SI reaction to race 1, which confirms the simultaneous introgression of the genes I-1 and I-2 (Carrer-Filho et al, 2016). Alambra and Siluet cultivars presented incompatible reaction to race 1 (SI) and moderately resistance to race 2.…”

“…The relationship between the three FOL races and tomato cultivars (I-1, I-2 and I-3), is race-specific and follows the gene-to-gene theory with incompatible reaction (SI) and, therefore, independent of the isolate (Inami et al, 2012). However, the partial resistance may vary as a function of the FOL isolate aggressiveness (Carrer-Filho et al, 2016) and consistent results are obtained when more than one pathogen isolate is used (Souza et al, 2010;Akram et al, 2014).…”
