The development of a multicellular organism such as a flowering plant relies on the patterned control of cell proliferation, differentiation, and growth. Research in the recent years has revealed that the control of cell-cycle progression and growth in plants is distinct from the regulation found in yeast or metazoans. Understanding these plant-specific regulators and networks, in which they act, is key for the understanding of plant development and is of current global importance as a basis for breeding of energy crops as well as the breeding of plants adapted for changing environmental conditions. However, the production of cells and their specification and differentiation overlap in time and space and build an intricate interrelationship of dependencies and feedback loops. In this network, the developmental context and the generation of specific cell types and tissues are often decisive.
多细胞生物(如开花植物)的发育依赖于细胞增殖、分化和生长的模式控制。近年来的研究表明,植物中细胞周期进程和生长的控制与酵母或后生动物中的调控不同。了解这些植物特异性调节剂和网络,以及它们的作用机制,是理解植物发育的关键,也是当前全球重要的基础,可用于培育能源作物以及培育适应环境变化的植物。然而,细胞的产生及其特化和分化在时间和空间上重叠,并建立了错综复杂的相互依赖和反馈关系。在这个网络中,发育背景和特定细胞类型和组织的产生往往是决定性的。
