| Popis: | Biotechnology has the potential to complement conventional plant breeding activities and facilitate the production of temperate grasses with improved productivity and persistence. It provides new techniques for generation of gene markers which may greatly enhance the capacity for cultivar discrimination and for tracking particular traits in breeding programmes. Through plant tissue culture and genetic transformation, it is possible to introduce genes from a wide variety of sources into elite breeding lines. This review provides a summary of recent advances in the application of these technologies to temperate grasses. The development of genetic transformation technology has, in general, been much slower for monocots than for dicots. However, all the elements required for production of transgenic plants are now coming into place. Regeneration systems are now available for many of the temperate grass species. Transformation systems have been used to produce transgenic plants of tall fescue and cock... |
