摘要：

Recent advances in plant cell and molecular biology have furthered the genetic manipulation of many plant species and advanced the options for crop improvement. Among the many targets for genetic manipulation, microspores offer several unique advantages: they are haploid, single-celled, and highly synchronized. In many plant species microspores develop into haploid embryos, and eventually haploid and doubled haploid plants, after in vitro anther or microspore culture. This induced in vitro developmental pathway of microspores, termed microspore embryogenesis, can be used to recover individual homozygous plants from microspores and microspore-derived embryos after genetic manipulation such as mutagenesis and gene transfer. The highly efficient microspore embryogenesis system in Brassica napus has been used successfully to obtain various mutants after microspore mutagenesis, and to achieve gene transfer mediated by Agrobacterium tumefaciens.
