O-methyltransferases (OMT) are important enzymes that are responsible for the synthesis of many small molecules, which include lignin monomers, flavonoids, alkaloids, and aroma compounds. One such compound is guaiacol, a small volatile molecule with a smoky aroma that contributes to tomato flavor. Little information is known about the pathway and regulation of synthesis of guaiacol. One possibl...

The tomato (Solanum lycopersicum L.) is cultivated all over the world and is a vegetable of significant economic importance. However, an increased production of the vegetable is directly connected with an elevated occurrence of pathogens limiting the production efficiency of the vegetable. Both, Tomato torrado virus and Pepino mosaic virus have been found to be serious disease factors. When not...

It has been known for some time that the root excretion of several species of Solanum stimulates the hatching of larvae from the cysts of the potato eelworm, Heterodera ro8tochien8i8 (Franklin, 1940). The isolation ofthe active principle in root excretion and the investigation of its chemical nature was first attempted, using the leachings from potato plants (Hurst, 1935, 1937), but the method ...

In the Mediterranean area, tomato soilborne pathogens used to be controlled by methyl bromide, particularly in protected cultivation. To decrease the use of this fumigant, non-chemical and chemical alternatives were developed and implemented in many Mediterranean countries. However, the success of the alternative depends on the degree of its integration in an integrated pest management programme.

tomato production, growing nearly 40 percent of world supply. The majority of fruit is processed into concentrated paste, but an increasing percentage is being used for products utilizing peeled fruit, either whole or diced. Important fruit quality attributes for paste production are soluble solids content (SS) and color of the blended product. Uniformity of color is more important for peeled f...
