In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.
我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异,经由子叶面积大小的测量,欧洲苦苣苔成员两片子叶呈现相似的生长速率,因此维持两片子叶等大的特徵,然而堇兰的大小子叶的确具有不同的生长速率,使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。
