Solanum Potato, Tomato

M. Friedman, Analysis of biologically active compounds in potatoes (Solanum tuberosum), tomatoes (Lycopersicum esculentum) and jimson weed (Datura stramonium) seeds. J. ChromatogrA 1054 (2004) 143-155. 

High elevation species include other underexploited products fibers, dyes, unorthodox food sources, grains such as quinua, kiwicha, kaniwa, exotic amaranths and little known tubers, e.g. ollucos and macas from the Punas of Peru and Bolivia, to mention just a few. Natural and immensely valuable germoplasm banks of wild potatoes, tomatoes and other solanum and cucurbitaceous species to improve existing cultivars, feed themselves from plants native to the alpine and subalpine belts. 

The Long Island case is a classic illustration of many of the factors known to enhance the development of resistance, including intensive commercial production of the insect s principal hosts (potato, tomato, eggplant), a very small number of wild hosts (Solanum rostratum, S. dulcamara) offering only minimal opportunities for avoidance of selection on untreated refugia, and a relatively isolated island location. 

Phytoalexin Solanum (Potato) Nicotlana (Tobacco) Lycopersicon (Tomato) Capsicum (Pepper) Solanum (Eggplant) Datura (Jimsonweed)... 

Alkaloid related to atropine, hyoscine. Found in Solanum and similar species, including potatoes, tomato plant leaves, Jerusalem cherry plant. Effects gastroenteritis, vomiting, collapse, twitching, coma. Confusion and hallucination can last for several days. 

Among the well-known Solanum species that have been chemically examined are S. nigrum, S. tuberosum (potato) and S. lycopersicum (tomato). From these and other species an alkaloidal glucoside, which was first prepared by Desfosses, has been obtained. This substance has been named solan ine, but it is not certain that all the plants recorded as containing solanine contain the same solanine or that the alkaloid has been obtained in a pure state in each case.

The fruit of a number of solanaceous plants, including tomato Lycopersicon esculentum), potato Solanum tuberosum) and eggplant Solarium melongena esculentum), have cholinesterase-inhibiting effects (Krasowski et al. 1997). They contain solanaceous glycoalkaloids o-solanine and o-chaconine, which are triglycosides of solanidine, a steroidal alkaloid derived from cholesterol. They are the only plant chemicals known to inhibit both acetlycholinesterase and butyrylcholinesterase, both in vitro and in vivo. 

The potato plant (Solanum tuberosum) is bushy, sprawling, and dark green, with compound leaves that resemble those of a close species, the tomato. The leaves are arranged in a spiral around the stem, and the flowers are arranged in clusters. They are about 1-inch wide and 5-petaled, and range in color from white to pale blue to purple. The plant is completely...

The common Irish potato and the tomato belong to the plant family Solanaceae, also called the nightshade family or the potato family. It is the same family to which the various nightshades belong, including belladonna. In fact, the potato and the tomato are of the same genus Solanum, and the leaves of both the potato plant and... 

SoLANUM. The steroid alkaloids in this genus arise mainly in the aerial portion, but the roots seem to be important as weU (282). Young organs seem to have a greater facility for generating alkaloids, and the alkaloid content of tomatoes and potatoes continually increases (231, 313, 370, 371). In the ripening plant alkaloid disappears from the roots, and the absolute content decreases partly in consequence of its translocation into the flowers, which in turn lose alkaloid as the seeds develop. When the plants are deprived of fruits there is an increase in alkaloid content in consequence of the loss of these organs of alkaloid breakdown (282). 

The wild tomato, Lycopersicon pennellii, and the wild potato, Solanum berthaultiif are two species which exhibit insect resistance conferred by glandular trichomes. S, berthaultii and L. pennellii have been the focus of efforts at Cornell University to transfer trichome-based insect resistance traits. This chapter reviews our knowledge of the biochemistry of glandular trichome-based insect resistance in these species.
