Movement is an important life history trait that can have an impact on local adaptation, and other evolutionary phenomena. We used a combination of nestbox survey data and genetic techniques (genotyping at 10 microsatellite loci) to quantify patterns of movement in common dormice Muscardinus avellanarius at two distinct sites ..

This study evaluated the mutagenicity and antimutagenicity of inulin in a chromosomal aberration assay in cultures of the meristematic cells of Allium cepa. The treatments evaluated were as follows: negative control - seed germination in distilled water; positive control - aqueous solution of methyl methanesulfonate (.. Read More»

In order to evaluate the genetic diversity and genetic structure of wild Dipsacus asperoides, we surveyed genetic polymorphisms in 288 individuals from 12 populations using ISSR. A total of 240 bands were amplified, among which 190 were polymorphic loci. At the species level, genetic diversity was found to be abundant: PPB.. Read More»

There have been many studies on Schistocerca gregaria and Locusta migratoria, which are important grasshopper pests in many parts of the world. However, the main pest grasshopper species in Brazil, S. pallens, Rhammatocerus schistocercoides and Stiphra robusta, are very poorly characterized genetically. We adapted a permanent .. Read More»

The low-light tolerance index was investigated in a set of 123 F2:3 lines during the seedling stage across 2 seasons, and the heredity of low-light tolerance was assessed via different genetic analysis methods. The results of the classical analysis showed that low-light tolerance is controlled by an additive-dominant polygene, and the polygenic inheritanc.. Read More»

Colony stimulating factors (CSF) have been considered to modulate liver regeneration (LR) after partial hepatectomy (PH) at the tissue level. However, it remains unclear about precise mechanism of action of CSF in regeneration at the cellular level. Therefore, eight rat liver cell types were isolated by Percoll gradient centri.. Read More»

FGD1 encoding a guanine nucleotide exchange factor, specifically activates Rho GTPase cell division cycle 42 (Cdc42). Dysfunction of FGD1 causes Aarskog-Scott syndrome (MIM #305400), an X-linked disorder that may affect bone and intellectual development. However, the relationship between FGD1 and intellectual developmental dis.. Read More»

Cotton (Gossypium spp) is one of the most economically important crops that provide the world’s most widely used natural fiber. Diseases such as Fusarium wilt and particularly Verticillium wilt seriously affect cotton production, and thus breeding for disease resistance is one of the most important goals of cotton breeding programs. Currently, poten.. Read More»

Cryopreservation injuries involve nuclear DNA damage. A protocol for cryopreserving and isolating adipocyte nuclei is proposed. Adipose tissue samples were directly analyzed (NoCRYO-0h), or stored at -196°C for 7 days without 10% dimethyl sulfoxide (DMSO) (CRYO-WO-DMSO) or with DMSO (CRYO-W-DMSO). To determine the effect of DMSO on cryopreservation tr.. Read More»

The nesting biology and the social structure of Euglossa fimbriata were studied based on two original nests found on the campus of the University of São Paulo, Ribeirão Preto, Brazil. Nest 1 contained two inseminated females, 39 sealed cells, one cell being provisioned, and six old and empty cells. Nest 2 contain.. Read More»
