Abstract

Sexual reproduction is an essential process in the propagation of flowering plants. The vegetative life cycle of plants starts with the fusion of male and female gametes in the course of double fertilisation. Investigations on the reproductive processes of agriculturally important crop plants, including cereals, are of great importance in breeding and seed sciences. For a long time much of our basic knowledge of sexual reproduction of the flowering plants has been derived from comprehensive information obtained from morphological (histological, cytological and ultrastructural) studies. Recent advances in plant cell and molecular biology have brought new, sophisticated experimental techniques to investigate and to micromanipulate the reproductive cells of plants for various biotechnological purposes (e.g. haploid induction, in vitro fertilisation, DNA transformation). The present paper gives a review of the results achieved in our cooperating laboratories within the fields of experimental flowering biology and biotechnology of sexual reproduction in cereals.
