Embryology and relationships of glucosinolate-producing plants

通过本项目的研究，我完成了15个产硫代葡萄糖苷类植物科Bataceae， Gyrostemonaceae, Akaniaceae， Bretschneideraceae的胚胎学研究。完成了Koeberlinia及其相关属Acanthothamnus、Brexia和Canotia的胚胎学研究；Salvadoraceae和Tovariaceae的种子解剖研究也正在完成。在此基础上，对硫代葡萄糖苷类植物的关系提出了以下建议。陀螺茎科是蝙蝠科的远亲，与Capparaceae和ressedaceae （Capparales）有密切的亲缘关系。蝙蝠科与15科中的任何一科都没有关系，最好将其作为一个独立的科来对待。3 .假牙科和假牙科均与无牙科等无牙科有密切的亲缘关系。小檗属（Koeberlinia）通常被归入小檗科（Capparaceae），与小檗属（Canotia）甚至小檗科（Capparaceae）的序数成员都无亲缘关系。这个属应该归入它自己的科。综上所述，产生硫代葡萄糖苷的家族被认为是在几个独立的进化谱系中进化而来的。为了更详细的比较和更有决定性的结论，对一些关键属的研究是至关重要的，包括Drypetes。

By means of this research project, I have completed embryological studies of Bataceae, Gyrostemonaceae, Akaniaceae, Bretschneideraceae of the 15 glucosinolate-producing plant families. Besides, the study of the embryology in Koeberlinia, as well as in putatively related genera Acanthothamnus, Brexia and Canotia, has been completed ; the study of seed anatomy in Salvadoraceae and Tovariaceae is also being finished up. Based on those works, the following suggestions have been presented for relationships of glucosinolate plants.1. Gyrostemonaceae, which are distantly related to Bataceae, have close affinities to Capparaceae and Resedaceae (Capparales).2. Bataceae have no relationships to any of the 15 families, and are better treated as a family of its own order batales.3. Both Akaniaceae and gretschneideraceae are closely related to families of Sapindales such as Sapindaceae.4. Koeberlinia, a genus which is usually placed in Capparaceae, has no close relationships to Canotia and even to ordinal members of Capparaceae. the genus ought to be assigned to a family of its own.In summary, glucosinolate-producing families are suggested to have evolved in several independent evolutionary lines. For further detailed comparison and more decisive conclusion, studies on some key genera including Drypetes are critical.
