“…Hence, evaluations of molecular statistics has had a serious effect on our perception of plant evolution and relations on all taxonomic levels, from the deep nodes dividing the key plant groups to species and populations [20]. Consequently, studying the levels of genetic diversity in natural populations is an essential precursor for the survey of plant species and will offer perceptions about the evolution of the species [55]. During the last two decades, there are little individual molecular studies involving Capparis and Cleome like the RAPD marker [54,56] and therefore, the AFLP marker [57].…”

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.

“…The lower CV, the smaller the dispersion level of the characters and vise versa. The CV value is often considered as the main indicator of variability (Zhang et al 2015;Stojnic et al 2016). The CV values of all traits and whole populations were exhibited in Table 3.…”

Abstract. Zulfahmi, Purwanto E, Parjanto, Yunus A. 2020. Phenotypic diversity and plasticity index of Eurycoma apiculata populations in Eastern Sumatra, Indonesia based on leaves morphology. Biodiversitas 21: 2923-2934. Eurycoma apiculata A.W. Benn. is a protected species in Indonesia, but diversity information of this species is limited. The objective of this study was to assess the phenotypic diversity, phenotypic plasticity index, and phenotypic differentiation among populations of E. apiculata in Eastern Sumatra, Indonesia based on leaves morphology. A total of 45 traits were measured on leaves from six populations studied. The result of this found that the phenotypic variation coefficient (CV) of the characters was ranged from 7.41% to 36.97%, revealed the abundant phenotypic variation in the species. The phenotypic CV values of the population varied from 13.95% to 24.10%. The CV values of all populations from the mainland Sumatra (17.75%) were lower than that from the Riau archipelago (23.61%), which revealed that phenotypic traits in mainland Sumatra were more stable compared to populations in the Riau archipelago. The population phenotypic plasticity index value of populations ranged from 0.41 to 0.51, and it was classified as a moderate level. The phenotypic differentiation coefficient among populations in this study was relatively low (VST = 21.06%), indicating a lower phenotypic variation among populations than within populations. The scatter plot of principal component analysis and UPGMA dendrogram divided the six populations studies into two groups. The findings of this study recommend that the in-situ conservation method is an effective protection strategy for E. apiculata while ex-situ conservation method can be implemented as a supplementary method.

“…La correlación morfológica-genética encontrada sugiere que estos niveles de variación responden de manera similar ante las presiones ambientales, aunque la plasticidad fenotípica parece tener patrones de heredabilidad independientes de la actividad inhibitoria, más asociados con factores geográficos y ecológicos (Zhang et al, 2015). Por el contrario, la presencia de uno de los genotipos sugeridos por el análisis de asignación bayesiana (azul) podría ser un indicador preciso de la eficiencia de los extractos para el tratamiento al ser exclusivo de las regiones con mayor capacidad; por lo que la inhibición de la α-glucosidasa tendría un fuerte componente heredable presente en El Arenal y en los Huertos obtenidos de esta región.…”

Tecoma stans es una planta utilizada en México y América Central para el tratamiento tradicional de la diabetes con un éxito variable dependiendo del origen, el entorno y otras fuentes de variación subyacentes. Para determinar la variación morfológica y genética asociada con una mejor inhibición de la α –glucosidasa, se probaron extractos etanólicos de siete poblaciones, tres silvestres y cuatro cultivos. La variación morfológica y genética se encuentran correlacionadas y ambas difieren significativamente entre poblaciones. La población de El Arenal obtuvo el máximo de actividad inhibitoria y presentó un genotipo particular compartido con dos cultivos que tuvieron una actividad similar, aunque no existen rasgos morfológicos asociados con el potencial antidiabético. Nuestros resultados sugieren un componente genético de la actividad terapéutica asociada con una fuente particular, pero una plasticidad morfológica independiente que podría no ser un indicador de la mejor respuesta terapéutica.
