Do potatoes and tomatoes have a single evolutionary history, and what proportion of the genome supports this history? [PDF]

open access: yes, 2009
Background Phylogenies reconstructed with only one or a few independently inherited loci may be unresolved or incongruent due to taxon and gene sampling, horizontal gene transfer, or differential selection and lineage sorting at individual loci.

The role of tomato wild relatives in breeding disease-free varieties

open access: yesGenetic Resources, 2022
Cultivated tomato (Solanum lycopersicum) is one of the most economically important and widely grown vegetable crops worldwide. However, tomato plants are often affected by biotic and abiotic stresses that reduce yield and affect fruit quality ...

Preliminary results of resistance of tomato accessions to late blight (Phytophthora infestans (Mont.) de Bary) [PDF]

open access: yesRatarstvo i Povrtarstvo, 2017
Late blight (LB) caused by Phytophthora infestans (Mont) de Bary is a highly destructive disease of tomato and appears worldwide. The losses caused by late blight depend on several factors, but main are weather conditions, genotype and amount of inoculum.

Balancing Selection at the Tomato RCR3 Guardee Gene Family Maintains Variation in Strength of Pathogen Defense [PDF]

open access: yes, 2012
Coevolution between hosts and pathogens is thought to occur between interacting molecules of both species. This results in the maintenance of genetic diversity at pathogen antigens (or so-called effectors) and host resistance genes such as the major ...

Genes Encoding Recognition of the Cladosporium fulvum Effector Protein Ecp5 Are Encoded at Several Loci in the Tomato Genome [PDF]

open access: yes, 2020
The molecular interactions between tomato and Cladosporium fulvum have been an important model for molecular plant pathology. Complex genetic loci on tomato chromosomes 1 and 6 harbor genes for resistance to Cladosporium fulvum, encoding receptor like ...

Efecto de antibiosis, antixenosis y la variación natural de tricomas de especies silvestres y comerciales en tomate sobre el desarrollo de Bactericera cockerelli

open access: yesScientia Agropecuaria, 2023
Bactericera cockerelli es una plaga económicamente relevante para cultivos de solanáceas. La presencia de tricomas foliares con la que cuentan ciertas especies silvestres constituye importantes recursos genéticos para programas de fitomejoramiento en ...

Oxidative burst and the activity of defense-related enzymes in compatible and incompatible tomato-Alternaria solani interactions

open access: yesSemina: Ciências Agrárias, 2014
The production of reactive oxygen species (ROS), hypersensitive response (HR), and the activity of the enzymes guaiacol peroxidase, catalase, polyphenol oxidase, B-1,3-glucanase and chitinase, were studied in leaves of resistant [CNPH 1287 (Solanum ...

Solanum galapagense‐derived purple tomato fruit color is conferred by novel alleles of the anthocyanin fruit and atroviolacium loci

open access: yesPlant Direct, 2022
One hypothesis for the origin of endemic species of tomato on the Galápagos islands postulates a hybridization of Solanum pimpinellifolium and Solanum habrochaites.

The long and winding road leading to the successful introgression of downy mildew resistance into onion [PDF]

open access: yes, 2007
Downy mildew resistance originating from Allium roylei Stearn provides a complete resistance to onions and is based on one, dominant gene. Since A. roylei can successfully be hybridized with onion (A.
