247 SOMATIC HYBRIDIZATION BETWEEN SOLANUM OCHRANTHUM AND LYCOPERSICON ESCULENTUM [PDF]

open access: yesHortScience, 1994
Incorporation of genes from wild species has been a major contributor to tomato improvement in recent years. Solanum ochranthum, a woody non-tuber bearing species, is a potential source of resistance against tomato diseases and insect pests but is genetically isolated from tomato. Somatic hybridization methods were developed to facilitate the use of S.

Induction of systemic resistance in tomato by the autochthonous phylloplane resident Bacillus cereus Indução de resistência sistêmica em tomateiro pela bactéria autóctone residente no filoplano Bacillus cereus

open access: yesPesquisa Agropecuária Brasileira, 2006
The objective of this work was to verify if the induced resistance mechanism is responsible for the capacity of a phylloplane resident bacteria (Bacillus cereus), isolated from healthy tomato plants, to control several diseases of this crop.

Development of a locus-specific, co-dominant SCAR marker for assisted-selection of the Sw-5 (Tospovirus resistance) gene cluster in a wide range of tomato accessions [PDF]

open access: yes, 2010
The best levels of broad-spectrum Tospovirus resistance reported in tomatoes thus far are conferred by the Sw-5 locus. This locus contains at least five paralogues (denoted Sw-5a through Sw-5e), of which Sw-5b represents the actual resistance gene.
