Somaclonal Variation in Soybeans
Tissue culture induced variation in regenerated plant progeny, up to R$\sb4$ generation (four cycles of self-pollination away from the regenerated plants) was studied. Several mutants/variants were seen, majority of them derived from the organogenic culture system. Variants such as wrinkled leaf …

Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
'Thornless Evergreen', Rubus laciniatus Willd. (2n = 4x = 28), is a periclinal chimeral blackberry in which a mutated thornless epidermis surrounds a core of cells with a thorny genotype. Adventitious shoots from roots are always thorny, and gametes carry the thorny gene. Via micropropagation, pure …

Somaclonal Variation in Inbreds and Testcrosses of Maize (Zea Mays L.) and the Possible Involvement of Transposable Elements
… regenerated from them which has been termed "somaclonal variation". The primary objectives of this research were to evaluate the amount of somaclonal variation in quantitatively inherited characters at both the inbred (R$\sb2$ family) and hybrid (R$\sb1$ x tester) levels and, using the …

The Use of Tissue Culture to Separate Apple (Malus Sp.) Chimeras Into Their Constituent Genotype(s) and to Induce Anthocyanin Production
To assess somaclonal variation, 'Gala', 'Royal Gala' and 'Jonagold' trees obtained via axillary and adventitious bud formation were compared ex vitro to conventionally grafted trees. In general, tissue culture-derived trees were relatively erect and their branch angles were relatively narrower in …

Evaluation of anther-derived, inbred, and hybrid populations of Streptocarpus X hybridus Voss
… to be of somatic cell origin, but exhibited somaclonal variation for overall morphology. Variation for leaf variegation and morphology, days to flowering, flowers per peduncle, peduncle length and leaf area were observed among progeny of anther-derived plants, indicating that heritable …

Genetic engineering for pest resistance in potato (Solanum tuberosum L.)
… used for plant regeneration on the frequency of somaclonal variation. A similar frequency of somaclonal variation was observed in plants regenerated from all three explant sources considered. This indicates that somaclonal variation is independent from the explant source used for plant …

Efficient production of doubled haploid plants through antimicrotubule agent treatment of anther-derived maize callus and the RFLP analysis of the maize anther culture response
… treatments suggest that no more than usual somaclonal variation was induced by these agents. Thus maize anther-derived haploid callus should be treated with these agents before plant regeneration in order to obtain a high frequency of doubled haploid plants.

AFLP Marker Analysis Of Monoploid Potato
… S. phureja "IVP 101." Little indication of somaclonal variation and haploid-inducer gene introgression was found in the monoploid band data suggesting genomic stability. Segregation of marker alleles that were heterozygous in the parent was distorted from the expected 1:1 ratio in both …

Molecular and Morphological Investigation of Astilbe
… complex because of its geographic distribution, variation within species, and the lack of adequate morphological characters to delineate taxa. To date, an inclusive investigation of the genus has not been conducted. This study was undertaken to (a) develop a well-resolved phylogeny of the genus …

Genetic studies of phenotypic variants in the woodland strawberry, (Fragaria vesca)
The diploid woodland strawberry (Fragaria vesca) is a rapidly developing translational model for members of the family Rosaceae and other plants. This thesis represents some of the first forward genetics studies evaluating putative T-DNA insertional mutants in F. vesca. The observed phenotypes …
