Internal phloem in an interspecific hybrid of cassava, an indicator of breeding value for drought resistance.
We examined the stem anatomy of Manihot esculenta Crantz and its hybrid with M. oligantha Pax. Cross-sections were stained with safranin-alcian blue. Manihot esculenta and its hybrid were found to have the same vascular structure in bicollateral bundles with internal phloem, which has been associated with drought resistance in other plant groups. If this association is established for cassava, ...
متن کاملInterspecific Hybridisation and Polyploidisation as Tools in Ornamental Plant Breeding
Interspecific hybridisation and polyploidy are recognized as the most important sources of evolution and domestication of flowering plants. In ornamental plant breeding these phenomena go hand in hand and can be observed in the breeding history of many ornamental crops (Rosa, Chrysanthemum, Gladiolus, Alstroemeria, Lilium, orchids etc). With lily as model crop techniques developed for overcomin...
متن کاملHeterochronic meiotic misexpression in an interspecific yeast hybrid.
Regulatory changes rapidly accumulate between species, and interspecific hybrids often misexpress genes. Hybrid misexpression, expression levels outside the range of both parental species, can result from cis- and trans-acting regulatory changes that interact abnormally in hybrids. Thus, misexpressed genes may contribute to hybrid sterility. However, in the context of a whole organism, misexpre...
متن کاملGenetic, embryonic and anatomical study of an interspecific cassava hybrid.
A molecular, anatomical and cytogenetic study of an interspecific hybrid between Manihot esculenta (cassava) and the wild species M. oligantha was carried out. Cytogenetics revealed relatively complete chromosome pairing and high viability of the pollen grains. Ovule structure examined by the clearing method showed polyembryony in 2.7% of the ovules. Doubling of the chromosome number resulted i...
متن کاملVolatile Compounds from Grape Skin, Juice and Wine from Five Interspecific Hybrid Grape Cultivars Grown in Québec (Canada) for Wine Production.
Developed from crosses between Vitis vinifera and North American Vitis species, interspecific hybrid grape varieties are becoming economically significant in northern areas, where they are now extensively grown for wine production. However, the varietal differences between interspecific hybrids are not well defined, nor are the relationships between hybrid grape and wine composition, which caus...
