Progress on Differentiation of Isolated Mesophyll Cells into Tracheary Elements in Common Zinnia (Zinnia elegans Jacq.)

概述了植物细胞分化的模式系统——管状分子分化实验系统的建立以及基于该系统的管状分子分化的生理学、细胞学、生物化学和分子生物学等方面的研究进展,并对今后的研究方向进行了展望。

Differentiation of tracheary elements （TEs） has been regarded as a model system for cytodifferentiafion in plants. Fukuda and Komamine established an efficient experimental system for TE differentiation from isolated single mesophyll cells of Zinnia elegans, which provided an excellent platform for the study of TEs differentiation at single cell level. The establishment of the system and the progress on physiology, cytology, biochemistry and molecular biology of the system-based TEs differentiation were summarized in this paper. At last, the future research direction of TEs differentiation was prospected.
