Somaclonal Variation in Sorghum

1996
Sorghum, Sorghum bicolor (L.) Moench (2n = 20), is the world’s fifth most important cereal crop. It is known under a variety of names and has been variously classified. Harlan and de Wet (1972) simply classified cultivated sorghum into five basic races (bicolor, guinea, caudatum, kafir, and durra) and ten intermediate races from combinations between ...

SOMACLONAL AND GAMETOCLONAL VARIATION

American Journal of Botany, 1984
For several years it has been recognized that introduction of plant cells into culture results in genetic changes. These genetic alterations have been recovered in the plants regenerated from cell cultures. More recently it has been recognized that this method of introducing genetic changes into crop plants could be used to develop new breeding lines ...

Somaclonal Variation in Cucurbits

1990
Cucurbits were among the first plants used by man, and the bottle gourd may be the only plant known in both the New and Old Worlds in early prehistoric times. Species of Cucurbita were major crops in the agriculture of the Aztec, Inca, and Mayan civilizations in Central and South America.

Insight into somaclonal variation

Plant Biosystems, 2001
ABSTRACT Somaclonal variation (S.V.) refers to mutational events occurring in tissue culture, although some permanent methylation processes should possibly also be included under this name. In this review, the possible causes as well as the mechanisms implicated in the induction of mutation in cultured cells are discussed.

Stress and Somaclonal Variation

2010
Plant 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 Tomato

1990
Lycopersicon 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.

Somaclonal Variation in Primula

1996
The 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.

Somaclonal Variation in Carnations

1990
The carnation (Dianthus caryophyllus L.) is a member of the Caryophyllaceae family. It is a semi-hardy perennial with branching stems, bearing linear, glaucous leaves in opposite and decussate pairs. Each stem forms a terminal flower and the inflorescence is a loose cyme.

Somaclonal Variation in Triticale

1990
Triticale (× 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 ...
