Dissecting the genetic control of root and leaf tissue-specific anthocyanin pigmentation in carrot (Daucus carota L.)
(Springer, 2019-05-29)
Purple carrots can accumulate large quantities of anthocyanins in their root tissues, as well as in other plant parts. This work investigated the genetic control underlying tissue-specific anthocyanin pigmentation in the ...
Spatial and temporal divergence of the torquatus species group of the subterranean rodent Ctenomys
(University of Amsterdam, 2018-03)
Subterranean rodents of the genus Ctenomys have experienced an explosive radiation and rapidly colonized the southern cone of South America. The torquatus group, one of the main groups of the genus, comprises several species ...
New data on the endemic Patagonian long-clawed mouse Notiomys edwardsii (Rodentia: Cricetidae)
(De Gruyter, 2008-12)
The monotypic Notiomys is the most poorly-known genus of Abrotrichini, a recently erected tribe of South American sigmodontine rodents. Based on a large sample, mostly recovered from owl pellets but including trapped ...
A new species of lutrine opossum, genus Lutreolina Thomas (Didelphidae), from the South American Yungas
(Oxford University Press, 2014-04)
This study presents the most comprehensive systematic revision of the genus Lutreolina to date, by means of genetic (mitochondrial DNA of 22 specimens) and morphologic (assessment of 262 specimens) evidence. Molecular ...
Mitochondrial-DNA phylogenetic information and the reconstruction of human population history: The south american case
(Wayne State University Press, 2017-06)
Mitochondrial DNA (mtDNA) sequences are becoming increasingly important in the study of human population history. Here, we explore the diffferences in the amount of information of diffferent mtDNA regions and their utility ...
The extrinsic and intrinsic apoptotic pathways are involved in manganese toxicity in rat astrocytoma C6 cells
(Pergamon-Elsevier Science Ltd, 2011-08)
Manganese (Mn) is a trace element known to be essential for maintaining the proper function and regulation of many biochemical and cellular reactions. However, chronic exposure to high levels of Mn in occupational or ...
Efeitos da contaminação por metais pesados e biomarcadores de impacto ambiental em peixes da bacia do rio São Francisco, MG
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MORFOLOGIAPrograma de Pós-Graduação em Biologia CelularUFMG, 2019-09-30)
Heavy metals are inorganic elements that can cause serious health problems in living organisms in general. Through industrial, rural and domestic waste, metals such as Cadmium (Cd), Lead (Pb), Copper (Cu), Chromium (Cr), ...
DNA barcoding supports identification of Malacobdella species (Nemertea: Hoplonemertea)
(Springer, 2015-01-10)
Background: Nemerteans of the genus Malacobdella live inside of the mantle cavity of marine bivalves. The genus currently contains only six species, five of which are host-specific and usually found in a single host species, ...
A phylogeographical perspective on the ex situ conservation of Aylacostoma (Thiaridae, Gastropoda) from the High Paraná River (Argentina-Paraguay)
(Wiley Blackwell Publishing, Inc, 2015-07)
Aylacostoma Spix, 1827, contains species that are the subject of focused conservation efforts under the auspices of the ‘Aylacostoma Project’, the only ex situ conservation programme for freshwater gastropods in South ...
Phylogeography and demographic inference in Nacella (Patinigera) concinna (Strebel, 1908) in the western Antarctic Peninsula
(PERGAMON-ELSEVIER, 2011-01)
Endemic to Antarctic ecosystems, the limpet Nacella (Patinigera) concinna (Strebel, 1908) is an abundant and dominant marine benthic invertebrate of the intertidal and shallow subtidal zone. In order to examine the ...
