The Capparaceae family is commonly recognized as a caper, while Cleomaceae represents one of small flowering family within the order Brassicales. Earlier, Cleomaceae was included in the family Capparaceae; then, it was moved to a distinct family after DNA evidence. Variation in habits and a bewildering array of floral and fruit forms contributed to making Capparaceae a “trash-basket” family in which many unrelated plants were placed. Indeed, family Capparaceae and Cleomaceae are in clear need of more detailed systematic revision. Here, in the present study, the morphological characteristics and the ecological distribution as well as the genetic diversity analysis among the twelve species of both Capparaceae and Cleomaceae have been determined. The genetic analysis has been checked using 15 ISSR, 30 SRAP, and 18 ISTR to assess the systematic knots between the two families. In order to detect the molecular phylogeny, a comparative analysis of the three markers was performed based on the exposure of discriminating capacity, efficiency, and phylogenetic heatmap. Our results indicated that there is a morphological and ecological variation between the two families. Moreover, the molecular analysis confirmed that ISTR followed by SRAP markers has superior discriminating capacity for describing the genetic diversity and is able to simultaneously distinguish many polymorphic markers per reaction. Indeed, both the PCA and HCA data have drawn a successful annotation relationship in Capparaceae and Cleome species to evaluate whether the specific group sort individual or overlap groups. The outcomes of the morphological and ecological characterization along with the genetic diversity indicated an insight solution thorny interspecies in Cleome and Gynandropsis genera as a distinct family (Cleomaceae) and the other genera (Capparis, Cadaba, Boscia, and Maerua) as Capparaceae. Finally, we recommended further studies to elucidate the systematic position of Dipterygium glaucum.

埃及的Capparaceae和Cleomaceae的系统修订：利用生态和遗传多样性评估Capparis和Cleome的一般划界

Capparaceae家族通常被认为是雀跃，而Cleomaceae代表Brassicales目中的小型开花家族之一。早些时候，醉蝶科被列入Capparaceae家族。然后，经过DNA鉴定，它被转移到一个不同的家庭。习性的变化以及令人迷惑的花卉和水果形态有助于使辣椒科成为一个“垃圾篮”家庭，其中放置了许多无关的植物。确实，Capparaceae和Cleomaceae家族显然需要更详细的系统修订。在这里，在本研究中，已经确定了辣椒属和油霉科这十二种植物的形态特征，生态分布以及遗传多样性分析。使用15个ISSR，30个SRAP，和18 ISTR来评估两个家庭之间的系统性纠缠。为了检测分子系统发育，基于区分能力，效率和系统发生热图的暴露，对这三个标记进行了比较分析。我们的结果表明，两个科之间存在形态和生态变异。此外，分子分析证实，在STRAP标记后面加上ISTR可以更好地描述遗传多样性，并且能够在每个反应中同时区分出许多多态性标记。确实，PCA和HCA数据均已在Capparaceae和Cleome物种中建立了成功的注释关系，以评估特定组是对单个组还是对重叠组进行排序。形态学和生态学特征以及遗传多样性的结果表明，作为一个独特的科（醉蝶科）和其他属（Capparis，Cadaba，Boscia和Maerua）的凤眼科和绞股蓝属的棘手种间的洞察力解决方案。最后，我们建议进行进一步的研究，以阐明白叶白屈菜的系统位置。
