Improving and elucidating factors regulating black walnut (Juglans nigra L.) clonal propagation
… recognized that black walnut was recalcitrant to clonal propagation techniques. Current black walnut propagation techniques such as grafting are time and labor intensive, and are less than optimal for commercial clonal black walnut production. Reports on black walnut propagation are limited, and …

QUERIES IN QUERCUS: FROM THE DEVELOPMENT OF A TISSUE CULTURE CLONAL PROPAGATION SYSTEM TO THE EVALUATION OF STRESS TOLERANT HYBRID WHITE OAKS FOR THE URBAN ENVIRONMENT
… the creation of a tissue culture system for the clonal propagation of hybrid white oaks. The second priority area was the development of evaluation methods to assess hybrid white oaks and other tree species for tolerance to stresses commonly found in the urban environment. A tissue culture system …

Propagation of asparagus (Asparagus officinalis L.) via somatic embryogenesis
… is important as an efficient system for clonal propagation. To achieve this technique, the first step is the initiation of callus followed by the induction of the embryos and their developments into plants. The optimized concentration of cytokinin and kinetin for callus formation from in …

The role of auxin and ethylene in adventitious root formation in Arabidopsis and tomato
… aerial plant tissues. Although important for clonal propagation of commercially important crop species, few studies have explored the mechanisms driving the development of these roots. This thesis research explored the hormonal controls and molecular mechanisms of adventitious root formation …

A microculture approach towards enhanced productivity and genetic improvement of pecan (Carya illinoensis)
… technique was developed as an alternative clonal propagation method. A unique apparatus was designed to splice the in vitro-derived scion and rootstock together during the micrografting process.

Molecular phylogenetics, systematics, reproductive safeguarding and chromosome evolution of the genus Lachenalia (Asparagaceae: Scilloideae)
… autonomous selfing, bird pollination and clonal propagation) in low insect abundance contexts (i.e., infertile fynbos heathland, and species which flower outside of the austral spring season). Ancestral state reconstructions identify an association with non-fynbos vegetation and …

Somatic embryogenesis in southern and tropical pine species: Loblolly pine (Pinus taeda), Longleaf pine (P. palustris) and Oocarpa pine (P. oocarpa)
… protocols and to enable full integration of this clonal propagation method into the breeding programs for pines.

Oh cryoprotectant, wherefore art thou cryoprotectant? Investigation of the permeation of common cryoprotectants into live rice callus cells by coherent Raman microscopy
… ferns for example, or agricultural plants where clonal propagation is the only way to conserve desirable traits, grapes, hops and bananas for example. Rather than collecting and saving seeds from these plants, researchers collect tissue samples, cool and preserve them in liquid nitrogen then warm …

Analysis of the relationship between genomic instability, heterozygosity levels and phenotype in Saccharomyces cerevisiae
… LOH occurs at a high frequency during JAY270's clonal propagation. These LOH events act against the long-term maintenance of genomic heterozygosity, yet about 60% of JAY270's genome has remained heterozygous over time. We hypothesized that specific heterozygous alleles may have a positive impact …

Dissecting key biomass traits through traditional QTL mapping, exploring novel functional genomics approaches, and investigating self-incompatibility in Miscanthus
… things, the necessity to establish fields via clonal propagation. Plants grown from seed segregate widely, resulting in a decrease in plot yield. Further, seed established plots increase the invasive potential of this non-native genus of grasses. Both of these concerns could be alleviated by …
