124 7. Conclusions The purpose of this Ph.D. work was oriented towards two points. 1. The analysis of organellar diversity among three plant species (Silene vulgaris, Silene latifolia and Aldrovanda vesiculosa). The three plant species had different morphological and physiological characters. The focus here was on two physiological points. 1.1. The reproduction system which is directly correlated with the mitochondrial DNA (in the case of CMS). This point was presented in the comparison between Silene vulgaris and Silene latifolia. 1.2. The different life strategy which is directly correlated with the organellar DNA diversity. This point was presented by the comparison between the two Silene species from one side and Aldrovanda vesiculosa from the other side. The later usually propagate vegetatively and live in different media (water), it present different life strategy under the umbrella of angiosperms. 2. The analysis of the inheritance of mitochondrial and chloroplast genome in Silene vulgaris. The study of this inheritance was facilitated by the high polymorphism available in the organellar DNA. This polymorphism could be detected by the different molecular markers used in this study. These molecular markers included either, gene coding regions markers previously used by D.E.McCauley and his team...
