“…Result showed that the 11, 17, 19, 24 and 29 genotypes were categorized as highly resistant (PDI 0.01 -10), resistant (PDI 10.01 -25), moderately resistant (PDI 25.01 -40), susceptible (PDI 40.01 -60) and highly susceptible (PDI > 60.01), respectively (Table 1). These results were in agreement with the findings of Gopal and Singh (2003), Govers (2005), Irzhansky and Cohen (2006), Nowicki et al, (2012), Nowicki et al, (2013), Forbes et al, (2014) and Nowakowska et al, (2014).…”

Resumo -O objetivo deste trabalho foi avaliar genitores com potencial de hibridação para o pré-melhoramento do tomateiro (Solanum lycopersicum) quanto à resistência à requeima. Foram utilizados seis acessos de tomateiro (BGH-2102, BGH-2117, BGH-2127, BGH-2130, BGH-2332 e BGH-2343 como genitores resistentes e 15 híbridos F 1 originários destes genitores. Utilizou-se o delineamento de blocos ao acaso, com três repetições. As plantas foram inoculadas com uma mistura de esporângios de Phytophthora infestans, agente etiológico da requeima, na concentração de 5x10 3 esporângios mL -1 . A área abaixo da curva de progresso da doença foi utilizada para avaliar a resistência. Realizou-se a análise dialélica, tendo-se considerado o efeito de genótipos como fixo. Estimou-se a capacidade geral e específica de combinação dos acessos. O padrão de resistência dos genitores e da maioria dos F 1 foi o mesmo que o das testemunhas resistentes. Foram observados: variabilidade genética aditiva entre os genitores, predominância de efeitos gênicos não aditivos e desvios de dominância bidirecional no controle do caráter. A frequência de alelos favoráveis e divergentes para resistência à requeima é maior nos acessos BGH-2117, BGH-2127 e BGH-2343.Termos para indexação: Phytophthora infestans, Solanum lycopersicum, capacidade combinatória, fonte de resistência. Hybridization potential among tomato accessions for pre-breeding for resistance to late blightAbstract -The objective of this work was to evaluate parents with hybridization potential for pre-breeding of tomato (Solanum lycopersicum) for resistance to late blight. Six tomato accessions (BGH-2102, BGH-2117, BGH-2127, BGH-2130, BGH-2332, and BGH-2343) were used as resistant parents and 15 F 1 hybrids originated from these parents. The design was a randomized complete block with three replicates. The plants were inoculated with a mixture of Phytophthora infestans sporangia, the etiological agent of late blight, at a concentration of 5x10 3 sporangia mL -1 . The area under the disease progress curve was used to evaluate resistance. Diallelic analysis was performed, considering the effect of genotypes as fixed. The general and specific combining ability of the accessions was estimated. The resistance pattern of the parents and of most of the F 1 was the same as that of the resistant controls. The following were observed: additive genetic variability among the parents, predominance of nonadditive gene effects, and bidirectional dominance deviations in the control of the trait. The frequency of favorable and divergent alleles for late blight resistance is higher in the BGH-2117, BGH-2127, and BGH-2343 accessions.

“…The importance of potato and tomato plant models in pathogenic interactions has significantly increased due to the completion of their genomic sequences and extensive arrays of mutants (Mueller et al 2009, The Potato Genome Sequencing Consortium 2011. From over 200 pathogens adversely affecting potato and tomato production, the oomycete P. infestans causing late blight remains the prominent reason of losses (Nowicki et al 2012b). By employing the hemibiotrophic mode of infection, the germinated pathogen spore first develops large biotrophic intracellular primary hyphae.…”

“…Recently, multiple areas of investigation have yielded tremendous progress in plantpathogens interactions. Next-generation (genome/ transcriptome) sequencing, resistance/ effector gene characterization (Haas et al 2009, Huang et al 2009, Mueller et al 2009, Raffaele et al 2010, Tian et al 2011, Woycicki et al 2011, micro-examination of the interactions between pathogenic fungi and host plants (Hood & Shew 1996, Hardham & Shan 2009, Savory et al 2010, and systems biology studies (Vleeshouwers et al 2011, Woycicki et al 2011, Nowicki et al 2012b, Raffaele et al 2010, Shibata et al 2010) have all proven highly effective tools in identifying the molecular and cellular basis of pathogen resistance and susceptibility. In particular, microscopic studies provide an exciting body of evidence regarding the pathogen biology or host plant reaction upon the perceived attack (Hood & Shew 1996, Hardham & Shan 2009, Savory et al 2010, Chen & Halterman 2011.…”

SummaryDramatic increase in confocal microscopy observation output has been gained by optimization of a simple trypan blue and aniline blue dual-stain and its application to two model pathosystems: Pseudoperonospora cubensiscucumber and Phytophthora infestans-tomato. Comparison of two dual-stain methods for confocal microscopy studies of P. cubensis-challenged cucumber leaves indicated the 'mild' approach most successful. This methodology provides simultaneous detection of different pathogen structures layered with the plant defense reactions. Moreover, ImageJ-assisted quantification of plant defense responses renders this method useful for addressing the host plant resistance reactions, as well as investigating the given isolate's pathogenicity. Application of this method for the P. infestans-challenged tomato leaf samples resulted in detection of several fungal infection structures, along with plant defense responses. The dual-stain also enabled detection of a peculiar aniline blue-sensitive material in the pathogen cell walls at the area of its hyphae emerging through the leaf stomata. Results presented herein indicate this method is applicable for detailed (possibly quantitative) investigations of multiple plant-fungal pathosystems.
