The Genus Luehea (Malvaceae-Tiliaceae): Review about Chemical and Pharmacological Aspects
Popularly known as "açoita-cavalo" (whips-horse), Luehea species (Malvaceae-Tilioideae) are native to America and are used in folk medicine as anti-inflammatory, antidiarrheal, antiseptic, expectorant, and depurative and against skin infections. Although there are studies showing the chemical constituents of some species, the active substances have not been properly identified. A systematic stu...
متن کاملSystematics and Evolution of Tarasa Philippi (Malvaceae): An enigmatic Andean polyploid genus
A molecular phylogenetic analysis of the tribe Malveae (subfamily Malvoideae, Malvaceae) was undertaken using the internal transcribed spacer region of the 18S-26S nuclear ribosomal repeat (ITS). This work represents the first exhaustive study to evaluate the infratribal circumscription and generic affinities using molecular sequence data. The ITS phylogeny indicates that the informal tribal al...
متن کاملExperimental hybridization and chromosome pairing in Kosteletzkya (Malvaceae, Malvoideae, Hibisceae), and possible implications for phylogeny and phytogeography in the genus
Kosteletzkya C. Presl, 1835 (Malvaceae, Malvoideae, Hibisceae) includes 17 species, all but two of which are about evenly distributed between Africa and the northern Neotropics. Fifteen of the species were brought into cultivation and used in a hybridization program in an attempt to shed light on evolutionary and phytogeographic relationships in the genus. Chromosome pairing (x = 19) at meiosis...
متن کاملRapid diversification of the cotton genus (Gossypium: Malvaceae) revealed by analysis of sixteen nuclear and chloroplast genes.
Previous molecular phylogenetic studies have failed to resolve the branching order among the major cotton (Gossypium) lineages, and it has been unclear whether this reflects actual history (rapid radiation) or sampling properties of the genes evaluated. In this paper, we reconsider the phylogenetic relationships of diploid cotton genome groups using DNA sequences from 11 single-copy nuclear loc...
متن کاملA new genus of Eucharitidae (Hymenoptera: Chalcidoidea), with notes on life history and immature stages.
Neolirata new genus (Eucharitidae: Eucharitini) is recognized based on males and females, with new descriptions of eggs, planidia and pupae. Redescriptions are provided for N. alta (Walker) and N. daguerrei (Gemignani) (comb. nov. transferred from Lirata) and a new description of N. furcula sp. nov. is presented. Females of N. alta deposit their eggs on the underside of leaves of Pseudabutilon ...
