Chemical products induce resistance to Xanthomonas perforans in tomato
The bacterial spot of tomato, caused by Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolar-S-methyl (ASM) (0.025 g.L(-1)), fluazinam (0.25 g.L(-1))...
متن کاملGenetic transformation of streptomycin resistance in Xanthomonas phaseoli.
Transformation of resistance to antibiotics was observed in Diplococcus pneumoniae by Hotchkiss (1951, 1952a, 1952b) and in Haemophilus influenzae by Alexander and Leidy (1953) and Alexander et al. (1954). In all these species only certain strains were capable of being transformed. The ability to be transformed has been termed competence; refractory strains are not competent. Austrian (1952) ha...
متن کاملCharacterization of hypersensitive resistance to bacterial spot race T3 (Xanthomonas perforans) from tomato accession PI 128216.
Bacterial spot of tomato is caused by four species of Xanthomonas. The accession PI 128216 (Solanum pimpinellifolium) displays a hypersensitive reaction (HR) to race T3 strains (predominantely Xanthomonas perforans). We developed an inbred backcross (IBC) population (BC(2)S(5), 178 families) derived from PI 128216 and OH88119 (S. lycopersicum) as the susceptible recurrent parent for simultaneou...
متن کاملTransformation of Cry1a105 gene to tomato in order to increase resistance to Heliothis
Tomato (Solanum lycopersicum L.) is an important vegetable in the world, it exposes to a wide range of pathogens and plant pests attack. Fruit worm is one of the most important the plant pest which mainly damage the fruit and causes the yield reduction. In this study, cry1a105 gene was cloned to pBI121 plasmid (with 35S promoter and Nos terminator), and was transferred to tomato by Agrobacteriu...
متن کاملMolecular mapping of hypersensitive resistance from tomato 'Hawaii 7981' to Xanthomonas perforans race T3.
Bacterial spot of tomato (Solanum lycopersicum) is caused by four species of Xanthomonas. The disease causes significant yield losses and a reduction in fruit quality. Physiological races have been described with tomato race 3 (T3) corresponding to strains of Xanthomonas perforans. The breeding line Hawaii 7981 (hereafter H7981) shows a hypersensitive reaction (HR) to race T3 strains conditione...
