Microspore regeneration as a tool for plant breeding Barley microspore regeneration as a model system
conference paper
Since androgenesis involves the control and reprogramming of developmental switches, it provides opportunities to investigate key elements in developmental control. Moreover, via androgenesis, fertile homozygous progeny from a heterozygous parent can be obtained in a single generation, thus significantly reducing time required in breeding programs and providing a major advantage in preparing F1 hybrid seeds as well. A strategy to develop a plant species independent microspore regeneration protocol would be of great significance for both the possibilities for studying basic processes in plant development and the economic importance. Therefore, barley microspore regeneration as model system is presented and some aspects in relation to dicotyledonous plants are given. For example the results of barley and African violet microspore regeneration are presented. Various factors that influence the microspore androgenesis such as the quality of the donor plants, the developmental stage of microspores, pre-treatment methods, microspore morphological changes, and application of plant growth regulators during induction of androgenesis are presented.
