In the current study, morphological traits and molecular markers were used to assess the genetic diversity of 29 cultivated tomatoes, 14 wild tomatoes and seven introgression lines. The three components of the principal component analysis (PCA) explained 78.54% of the total morphological variation in the 50 tomato genotypes assessed. Based on these morphological traits, a three-dimensional PCA ...

Sequence variation was sampled in cultivated and related wild forms of tomato at fw2.2--a fruit weight QTL key to the evolution of domesticated tomatoes. Variation at fw2.2 was contrasted with variation at four other loci not involved in fruit weight determination. Several conclusions could be reached: (1) Fruit weight variation attributable to fw2.2 is not caused by variation in the FW2.2 prot...

BACKGROUND Foodborne outbreaks of Shigella infection are uncommon and tomatoes are an unusual vehicle. We describe a large, multiple-restaurant outbreak of Shigella flexneri serotype 2a infection that was associated with tomatoes. METHODS We conducted nationwide surveillance and a case-control study, collected fecal specimens for culture, and measured the survival of the outbreak strain of S....

The main objective of this project is to present the design and implementation an automated greenhouse in a home garden Organic Solanum Lycopersicum, commonly known as organic tomatoes, controlled with fuzzy logic cold humid climate, demonstrating that agroecological tomato greenhouses can be made places without use chemicals, help advanced controllers, case, controller. For development, diffus...

Nitrogen is an indispensable element for plants, being the fourth element as a percentage of plants by carbon, oxygen and hydrogen, in his absence they do not develop as a result of inhibition of chlorophyll synthesis and loss of nutritional values of fruits, hence the efficiency of this element in plans fertility of all plants. Conversely nitrogen (N), plants sensitizes the fall and decreases ...

Quality differences between organic and conventional fresh tomatoes (unprocessed) and frozen tomatoes (processed) are evaluated by using a capillary rising picture method (capillary dynamolysis). The best pictures showing the differences most sharply between organic and conventional samples were prepared with 0.25-0.75% silver nitrate, 0.25-0.75% iron sulphate and 30-100% sample concentration. ...

Lycopene is a carotenoid that has antioxidant properties and imparts the red pigment in some fruits and vegetables. Tomato (Lycopersicon esculentum Mill.) is one of the predominant lycopene sources in a typical North American diet. Current methods to assay lycopene content in fruit are time consuming, expensive, and use hazardous organic solvents. Here, we report a method by which light absorba...

Fresh tomatoes higher in lycopene content than standard varieties have recently been designed. We hypothesized that consumption of fresh, high lycopene tomatoes (HEC) for 3-weeks, as compared to standard fresh tomatoes, (LEC) would result in significant increases in serum lycopene and reductions in oxidative stress and inflammation. Forty healthy adult men (37.5%) and women (62.5%) age 55.3±4.7...
