Abstract 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.

High Diversity

Mango (Mangifera indica L.) is a fruit crops belong to the family Anacardiaceae and is the oldest cultivated tree worldwide. Cultivars maintained in Egypt have not been investigated previously. Mango was first brought to Egypt from South Asia. Morphological and molecular techniques were used to identify the genetic diversity within 28 mango cultivars. SSR and EST-SSR were used for optimizing germplasm management of mango cultivars. Significant variations were observed in morphological characteristics and genetic polymorphism, as they ranged from 0.71% to 100%. High diversity was confirmed as a pattern of morphological and genotypes data. Data from the present study may be used to calculate the mango relationship and diversity currently grown in Egypt.

The Family

Kalliapseudidae is a family of shallow burrow–dwelling and fossorial marine and estuarine tanaidaceans. There are currently 39 known species in 12 genera and three subfamilies. They are distributed throughout the world’s tropical, subtropical, and temperate coastal waters and, with a few known exceptions, are restricted to depths of less than 200 m. The phylogeny of Kalliapseudidae is assessed to test the monophyly of currently accepted subfamilies and genera, based largely on examination of material loaned from various museums and institutions. Multiple exemplars from other apseudomorph families were also included in the ingroup to test the monophyly of the family. Parsimony analyses included 41 terminal taxa and 64 binary and multistate morphological characters. Analyses based on successive weighting resulted in 20 most parsimonious trees. The strict consensus tree of these most parsimonious trees supported Kalliapseudidae, Kalliapseudinae, Tanapseudes, Cristapseudes, and Mesokalliapseudes as monophyletic. The genus Kalliapseudes could not be resolved, but constraining it to be monophyletic resulted in a significantly worse tree. The subfamilies Hemikalliapseudinae and Tanapseudinae were recovered as polyphyletic and paraphyletic, respectively, but without support. Constraining them to be monophyletic did not result in a significantly worse tree. Results indicated high levels of homoplasy in three morphological characteristics traditionally used to differentiate groups. Alokalliapseudes macsweenyi is transferred back to the genus Mesokalliapseudes, rendering Alokalliapseudes a junior subjective synonym. Nine new taxa, including six species of Kalliapseudes and one species of the genus Cristapseudes, and one new genus (Phoxokalliapseudes) and species (P. singaporensis) were discovered and described. Two species of Kalliapseudes (K. gobinae and K. multiarticulus) are transferred to Phoxokalliapseudes n. gen. Neotypes are designated for K. magnus, C. omercooperi and M. schubarti, and a lectotype is designated for K. mauritanicus. Distribution maps, illustrated keys to the subfamilies, genera and species, and preliminary remarks on biogeographic history are also presented.

The genomic information available in barnyard millet is very scarce though it is a rich source of highly digestible proteins and dietary fibre with good amounts of soluble and insoluble fractions. In the present investigation, 64 maize and finger millet genomic SSRs were used for cross transferability analysis among barnyard millet cultivated and wild species for identification of polymorphic markers, syntenic regions, genetic diversity and population structure analysis. Out of the 64 SSRs, only 39 (61%) were amplified across the barnyard millet genotypes. The PIC values of all the polymorphic loci for 24 barnyard millet genotypes varied from 0.25 to 0.73 at an average of 0.35. Based on the values of different parameters i.e., PIC values (andgt;0.7), gene diversity (andgt;0.6), inbreeding coefficient (andgt;0.27), the SSR loci bnlg2323 and bnlg2123 were observed to be highly polymorphic. Polymorphism comparison of maize and finger millet SSRs revealed that maize microsatellites were highly transferable, more polymorphic and were able to distinguish barnyard millet genotypes clearly. Results of population structure and genetic diversity analysis were similar in differentiating the barnyard millet genotypes into two groups. The structure analysis showed that all genotypes were pure lines (no admixture) while two (IEC514, and IEC409) had mixture of alleles from other genotypes of population which is depicted from the SSRs used in the study. The present study enriched the barnyard millet genetic resources by identifying suitable polymorphic markers of maize and finger millet for diversity analysis, cultivar identification and marker assisted breeding programmes.
