Advances in the Molecular Mechanism of in vitro Plant Organogenesis
植物离体器官发生控制机理研究进展

Plant organ regeneration has an important role in plant reproduction and genetic engineering, and also provides an experimental system to study molecular mechanism of plant development. So far, almost all of vegetative and reproductive organs have been regenerated in vitro, which might be helpful to further understand the molecular mechanism of plant organogenesis. In this review, regulation of gene expression and functions of a few genes involved in the regeneration of vegetative organs are introduced. Further, roles of organ identity genes, such as HAG1 and HoMADS1, are evaluated in reproductive organ development. Finally, we discuss the questions which may be focused in the future study.
