Molecular screening of tomato (Solanum lycopersicum L.) genotypes for resistance alleles against important biotic stresses

Assessment of genetic variation in Bulgarian tomato (Solanum lycopersicum L.) genotypes, using fluorescent SSR genotyping platform

Genetic variability in modern crops is limited due to domestication and selection processes. Genetic variation in eight Bulgarian tomato varieties and breeding lines (variety Plovdivska karotina, variety IZK Alya, L21β, L53β, L1140, L1116, L975, L984) differing in their morphological and biochemical composition was assessed using a highly efficient and low-cost fluorescent simple sequence repea...

Preliminary Study on Hepatoprotective Activity of Tomato (Solanum lycopersicum L.) Pulp Against Hepatic Damage in Rats

Tomato was evaluated for its liver protective role against carbon tetrachloride (CCl ) induced liver 4 damage in Wister albino rats. Animals were orally treated with tomato pulp (20 and 40 mL/kg body weight) for seven days followed by intraperitoneal injection (2 ml/kg) of 50% v/v CC1 on the last day. The degree of 4 protection was determined by measuring levels of serum biochemical parameters ...

Functional Characterization of a Syntaxin Involved in Tomato (Solanum lycopersicum) Resistance against Powdery Mildew

Specific syntaxins, such as Arabidopsis AtPEN1 and its barley ortholog ROR2, play a major role in plant defense against powdery mildews. Indeed, the impairment of these genes results in increased fungal penetration in both host and non-host interactions. In this study, a genome-wide survey allowed the identification of 21 tomato syntaxins. Two of them, named SlPEN1a and SlPEN1b, are closely rel...

Phenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus

Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...
