Red clover (Trifolium pratense).
Genetic modification of plants by the insertion of transgenes can be a powerful experimental approach to answer basic questions about gene product function. This technology can also be used to make improved crop varieties for use in the field. To apply this powerful tool to red clover, an important forage legume, a population of red clover with a high potential for regeneration in tissue cultur...
متن کاملRed Clover (Trifolium pratense)
Brief Background: Red clover is a legume, which like soy contains "phytoestrogens" (plant-based compounds structurally similar to estradiol, capable of binding to estrogen receptors as an agonist or antagonist). Red clover was traditionally used to treat asthma, pertussis, cancer, and gout. In modern times, isoflavone extracts of red clover are most often used to treat menopausal symptoms, as a...
متن کاملIncompatibility in Autotetraploid Trifolium Pratense.
RIFOLI U M pratense L. is a highly self-incompatible species. An oppositional Tsystem of incompatibility has been established in this species by WILLIAMS and SILOW (1933). Artificially induced autopolyploids have been produced by LEVAN (1948) and FRANDSEN (1948) and selections have been carried out for several generations to improve their fertility. But no work has been done to study the effect...
متن کاملCyanotypic frequencies in adjacent and mixed populations of Trifolium occidentale Coombe and Trifolium repens L. are regulated by different mechanisms.
The cyanogenic polymorphism in Trifolium repens is caused by the variation in two genes, the interaction of which produces four distinct cyanotypes. Along the Atlantic coasts of Bretagne, T. repens is sometimes found in populations mixed with the related species Trifolium occidentale, although the latter species usually occurs only in a narrow fringe along the coast, whereas T. repens is a more...
متن کاملOppositional Allelism in Diploid and Autotetraploid Trifolium Hybridum L.
HE selfand cross-incompatibilities of a number of obligately cross-polliT nated species of flowering plants are genetically determined by series of multiple oppositional alleles. The oppositional or personate incompatibility system was first described, with substantiating data, by EAST and MANGELSDORF (1925) for Nicotiana species. The existence of oppositional alleles has been subsequently demo...
