摘要
本文根据胶束假说(Gabarayeva and Hemsley, 2006;Hemsley和Gabarayeva, 2007),这表明自组装在发展中的参与。对远缘分类群中5个种的外胚层(含孢粉素的部分)的发育进行了详细的追踪,并将其解释为胶束序列。在体外进行的以胶体系统的物理化学规律(疏水关系)为驱动动机的类叶状结构的实验建模,有力地证明了胶束假说的相关性,并强调了这些研究的一个有希望的特征。讨论了复杂生物壁排列中基因控制与自组装的关系。
[The role of genetic control and self-assembly in gametophyte sporoderm ontogeny: hypotheses and experiment].
A review of our own and literature data on mechanisms of sporoderm development (of the wall of pollen grains and spores) is represented here in the light of colloidal relationships-so-called micellar hypothesis (Gabarayeva and Hemsley, 2006; Hemsley and Gabarayeva, 2007) which suggests the participation of self-assembly in development. The development of the exines (ofsporopollenin-containing part of the sporo- derm) in 5 species from remote taxa has been traced in detail and interpreted as a micellar sequence. The experimental modelling of exine-like structures, carried out in vitro where physico-chemical regularities of colloidal systems (hydrophobic relationships) were the driving motive, is a strong evidence of the relevance of the micellar hypothesis and emphasizes a promising character of these studies. The correlation between ge- nomic control and self-assembly in arrangement of complex biological walls is discussed.
