“…During this study, we realized that morphological variability has led to much confusion in distinguishing species using the diagnostic characters proposed by different authors (Zohary, 1960;Davis, 1965;Jacobs, 1965;Al-Gohary, 1982;Higton & Akeroyd, 1991;Heywood, 1993;Fici & Gianguzzi, 1997;El-Karemy, 2001). Species identification is hard or even impossible when only vegetative parts are present, which is often the case during collection.…”

Taxonomic considerations among and within some Egyptian taxa of Capparis and related genera (Capparaceae) as revealed by RAPD fingerprinting.-This investigation was carried out to assess the taxonomic relationships among eight taxa of the Egyptian members of Capparaceae based on random amplified polymorphic DNA markers, and to compare the results with those obtained from morphological studies. A total of 46 bands were scored for three RAPD primers corresponding to an average of 15.3 bands per primer. The three primers (A03, A07 and A09) revealed eight polymorphic RAPD markers among the studied taxa ranging in size from 200 bp to 1000 bp. Jaccard's coefficient of similarity varied from 0.28 to 0.84, indicative of high level of genetic variation among the genotypes studied. uPGMA cluster analysis indicated three distinct clusters, one comprised Cleome amblyocarpa and Gynandropsis gynandra, while another included two clusters at 0.74 phenon line; one for Capparis decidua, and the other for Capparis sinaica and all varieties of Capparis spinosa. The four varieties of Capparis spinosa were segregated at 0.84 phenon line. However, one of these varieties was more closely related to Capparis sinaica than to the other three varieties of C. spinosa. The RAPD analysis reported here confirms previous studies based on morphological markers.Key words: Capparis; Cleome; cluster analysis; Egypt; genetic relationships; Gynandropsis; RAPD-PCR; taxonomy; uPGMA. ResumenConsideraciones taxonómicas sobre algunos taxones egipcios de Capparis y géneros relacionados (Capparaceae) a partir de RAPDs.-El objetivo de este trabajo es investigar las relaciones taxonómicas entre ocho taxones pertenecientes a las Capparaceae en base a marcadores de tipo RAPD, y comparar los resultados con los obtenidos previamente en estudios morfológicos. Se han contabilizado un total de 46 bandas para tres pares de cebadores, con una media de 15,3 bandas por cebador. los tres pares de cebadores (A03, A07 y A09) revelan ocho marcadores polimórficos entre los taxones estudiados, de entre 200 y 1000 pares de bases. El coeficiente de similaridad de Jaccard varía entre 0,28 y 0,84, indicativo de un alto nivel de variación genética entre los genotipos estudiados. El análisis uPGMA muestra tres grupos distintos, el primero comprende Cleome amblyocarpa y Gynandropsis gynandra, mientras que el segundo incluye dos grupos a la altura del valor 0,74 del dendrograma: uno se corresponde con Capparis decidua, y el otro comprende Capparis sinaica y todas las variedades de Capparis spinosa. las cuatro variedades de C. spinosa se segregan a la altura del valor 0,84 del dendrograma. Sin embargo, una de estas variedades está más relacionada con C. sinaica que con las otras variedades de C. spinosa. El análisis de RAPD confirma los resultados de estudios anteriores basados en caracteres morfológicos.

“…C. rotundifolia contains leaves, which are densely sparsely with swollen-based hairs (Figure 1). The genus Cadaba also includs other 30 species which are distributed from Northeast Africa to South west Arabia (Karemy, 2001). In Ethiopia, C. rotundifolia is widely distributed in desert plain situated mainly within the Rift Valley lies in the Eastern and North Eastern part (Ahmed et al, 2017;Tikssa et al, 2009).…”

“…The taxonomic approach of the family in Egypt is interested only on seed morphology [12], leaf anatomy [13], and pollen morphology [14]. The systematic review of the natural species of Capparaceae (except Cleome) announced the unclear occurrence of Boscia angustifolia, while Capparis spinosa is described by three varieties, viz., deserti, spinosa, and inermis [15]. Spilt from Cleomaceae may be unreasonable since complications are met in selecting the genera.…”

Background 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. Results 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. Conclusion 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.
