In Brazil, 35 species have been recorded (ca. 54% of the family’s diversity), wherein the greatest diversity is found in the Amazon (27 spp.), Atlantic Forest (9 spp.) and Cerrado (6 spp.) domains. This work is part of the “Flora do Espírito Santo” project, which aims to contribute to the knowledge of the state’s floristic diversity. Field expeditions were carried out from January/2019 to March/2020. Humiriaceae, in the state of Espírito Santo, is represented by six species distributed in four genera: Humiria, Humiriastrum, Sacoglottis and Vantanea. Among the registered genera, Vantanea is the most diversified, with three species. In the dense rain forest, all Humiriaceae species recorded here were found, followed by pioneer formations of restingas, with four species and seasonal semideciduous forest, with one species. The main morphological characters that assist in the delimitation of Humiriaceae species in Espírito Santo, are androecium characteristics, such as length (homodynamous or heterodynamous), number of stamens and the number of their series, as well as anther morphology.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The murundus are small and scattered earthmounds with a differentiated flora of its surrounding. In our study site (Campo Maior, Piauí, Northeastern Brazil), we classified them in three categories: presence of carnaúba (PC), presence of tucum (PT), and with the absence of palm trees (AP). Here, our goals were (1) to explore alpha diversity using the richness estimator and abundance distribution rank, expecting that palm trees could influence the richness of plant species on murundus; (2) analyzing the species richness-area relationship in the murundus, following the assumptions that the largest one holds more species; (3) find the changes in the species composition (beta diversity) between the three categories of murundus, assuming which the presence of palm trees influence the species composition; and (4) investigate if the distance between murundus is a decisive factor in the species composition, where the closest murundus are the most similar in species composition. Ours results showed that palms trees do not influence the richness of the murundus, the largest murundus are the richest ones, and the turnover predominantly determines beta diversity in the different murundus categories. Furthermore, the distance between the murundus did not determine its floristic similarity. Overall, we demonstrated which the species of palm trees are not the main drive of the plant assemblage in the murundus, however its size comprises a major factor in the richness, with great species substitution, which explains the high plant diversity.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the reports, the botanical family Fabaceae deserves to be highlighted among the taxa that make up the Brazilian flora due to its richness of species and economic interest. In this sense, the objective of the present study was to retrieve information regarding Fabaceae cited in Historia Naturalis Brasiliae by naturalists Piso & Marggraf (1648), with the aim of identifying potential resources of Brazilian flora in conjunction with local knowledge about potential species today and how historical changes have influenced the use of these plant resources. Documentary data were analyzed in the original source and in Pickel’s 2008 review work (Flora do Nordeste do Brasil). The information was organized in a database and analyzed qualitatively and quantitatively. The analysis recovered 49 species belonging to the botanical family Fabaceae in the work. Of this total, 33 species and two genera had their use mentioned in the work, the reports of which were subdivided into four categories, with the highest percentage being for the category of medicinal use (69.23%). Of the plants reported for medicinal use, 18 species and one genus had no records in contemporary works. The analyses presented here contribute to expanding the knowledge of Fabaceae, the recovery of knowledge of plants from past centuries, and the discussion of the influence of factors that cause historical changes in use patterns, thus enriching studies in the field of botany, particularly historical ethnobotany.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research refinement demonstrated the pharmaceutical potential of M. oleifera and its phytochemicals, given its antidiabetic effect. The prospective analysis showed the amount of application within IPC A61K in health area. The secondary metabolites present in M. oleifera, glucosinolates, flavonoids, and phenolic compounds may be responsible, in part, for the disease control hypoglycemic actions. Glucosinolates, when metabolized by salivary enzymes, give rise to sulforaphanes that act in preventing type 2 diabetes and in reducing insulin resistance. Flavonoids interact with intestinal enzymes by modifying carbohydrate metabolism by regulating glycemic levels, in addition to increasing insulin sensitivity. Phenolic compounds increase the expression of glucose transporters (GLUT4) and reduce the synthesis of fatty acids and cholesterol, contributing to the reduction of glucose resistance and blood sugar control. Moringa oleifera can be used as complementary therapy of the type-2 diabetes.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67284278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed microsatellite markers for P. pubescens and transferred them to P. emarginatus to further genetic diversity investigation of these species. From genomic sequences of P. pubescens, obtained via the Illumina MiSeq platform, it was possible to identify 6,514 microsatellite regions, to design 5,419 primer pairs, and to test 30 markers amplification. We provide 26 polymorphic microsatellite markers, 10 of which were genotyped in 48 individuals per species. The number of alleles per locus range from 3 to 16, with high average genetic diversity ( P. pubescens HE = 0.753; P. emarginatus HE = 0.691). The genotyped markers have a high paternity exclusion probability (Q values greater than 0.99) and low probability of identity, indicating that set of loci is capable of individual discriminating in P. pubescens and P. emarginatus. Microsatellite markers provided in this study are a tool for population genetics studies and conservation of the two species and can be applied to closely related non-model species.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"128 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67284289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the history of the institution published in Hortus fluminensis (1894), Rodrigues described a scene in which the regent prince John VI, when solemnly founding the garden in 1809, would have planted an imperial palm with his own hands, a specimen known as palma mater. The period was full of political tension, due to the sudden change of government with the Proclamation of the Republic, on November, 15, 1889. In this article we discuss whether the name of Rodrigues was a consensus for director of the garden. Although he was recognized in Brazil and abroad as an important Brazilian scientist, he was a steadfast Monarchist. In this context, we present a critical analysis of the discourse involving the palma mater. The results suggest this discourse is historically unlikely, leading us to believe it is the case of an ‘invented tradition’ by the new director, expressed as an allegory with political goal. Other studies are necessary to better understand his goals, his interlocutors and possible reactions provoked by such manifestation.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67284425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
