Applications of Somaclonal Variation
Nature Biotechnology, 1986While recombinant DNA techniques offer promise for modification of crops, the relative paucity of knowledge of plant genetics and biochemistry has delayed development of recombinant DNA–based products using higher plants. However, somaclonal variation offers an opportunity to uncover the natural variability in plants and to use this genetic variability

Somaclonal Variation in Zinnia
1996The genus Zinnia (Asteraceae, Helianthus tribe) consists of about 17 species of annuals, perennial herbs, or small shrubs native to the southwestern United States and Central and South America. Zinnia elegans Jacq., native to Mexico, is a commercially important herbaceous annual grown as a bedding plant or cut flower.

Somaclonal Variation in Cotton
1998The extent of genetic variability in the base population determines the success of any crop improvement program. During the past few years, various in vitro methods have been employed to induce genetic variability/somaclonal variation for resistance to pests, diseases, salt, high temperature, etc. in a number of agricultural crops (see Bajaj 1996). The

Somaclonal Variation in Tomato
1990Lycopersicon species originated in the Andean region of South America. Domestication of the tomato began in Mexico, where wild populations of L. esculentum var. cerasiforme are still found. From this region the cultivated tomato spread first to Europe in the Mediterranean region and then to North America in the 18th century.

1990
For several thousand years, conventional breeding techniques have been used to genetically improve peaches. Now we have tissue culture and genetic engineering technologies at our disposal that will enable us not only to work at the whole plant level, but also at the organ, tissue, cell, protoplast, organelle, chromosome, and gene levels in our efforts ...

Somaclonal Variation in Pelargonium
1990The genus Pelargonium, l’Her. Storksbill (Geraniaceae) comprises plants of various habit, often succulent: the leaves, either digitately or pinnately veined, are entire, lobed, or dissected; the flowers, of many colors, usually have five sepals and petals, the two upper petals mostly larger, the lower mostly narrow and occasionally very small; there ...

Stress and Somaclonal Variation
2010Plant species have developed in the course of evolution through a series of mechanisms which optimize their relationships with the environments in which they live. As plants are sessile organisms, they cannot avoid extreme stress situations which can be deleterious. Although the word stress is well known, it has proven to be a very elusive concept, and

Somaclonal Variation in Chicory
1990Chicory (Cichorium intybus L., n = 9) is a species of the Compositae family that is concentrated in the warm temperate zone of the northern hemisphere, particularly in Europe and around the Mediterranean Basin. According to Vavilov (1951), the Mediterranean is the primary center of distribution of this plant.

Somaclonal Variation in Triticale
1990Triticale (× Triticosecale Wittmack) is a man-made cereal grain developed through the hybridization of wheat (Triticum aestivum or Triticum durum) and rye (Secale cereale) The first fertile hybrid was developed by Rimpau in 1891 but interest in developing triticale as a potential crop species did not occur until after the discovery of the chromosome ...

Somaclonal Variation in Primula
1996The genus Primula, a member of the Primulaceae family, consists of more than 500 species, which are naturally distributed in areas of the temperate zone in Europe, South America, North Africa, and Asia, including Japan (Smith and Forrest 1929). Most of them are perennial, hardy plants which bloom from early spring to summer.
