Buffalo; Genotype; Milk; PCR-SSCP; SNP

Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the ... more

Calpastatin; meat quality; Meat tenderness; Myostatin; PCR-SSCP

In Brazil, most sheep are of the Santa Inês breed, which shows rusticity in breeding and grazing systems, being able to offer better adaptation characteristics for animals with meat production ability, such as the Texel and Dorper sheep. They can also improve meat production in animals that have better characteristics for milk production, such as Lacaune and East ... more

Aedes aegypti; Isodillapiole; qRT-PCR

The yellow fever mosquito Aedes (Stegomyia) aegypti is the main vector of dengue arbovirus and other arboviruses. Dengue prevention measures for the control of A. aegypti involve mainly the use of synthetic insecticides. The constant use of insecticides has caused resistance in this mosquito. Alternative studies on plant extracts and their products have ... more

Coffea arabica; Developmental stages; qRT-PCR

Coffee seeds begin to develop shortly after fertilization and can take 6 to 8 months to complete their formation, a period during which all the characteristics of the mature seed are determined, directly influencing physiological quality. However, little is known about the molecular mechanisms that act during coffee seed maturation. The objective of the current study was to analyze ... more

AHL25; Arabidopsis thaliana; Artificial micro-RNA; AtExpA8; qRT-PCR

Micro-RNAs are cellular components regulating gene expression at the post-transcription level. In the present study, artificial micro-RNAs were used to decrease the transcript level of two genes, AtExpA8 (encoding an expansin) and AHL25 (encoding an AT-hook motif nuclear localized protein) in Arabidopsis thaliana. The backbone of the Arabidopsis ... more

Immune response; Malaria; Phylogenetic relationship; qRT-PCR; Resistance to insecticides
Anopheles darlingi is the most anthropophilic mosquito related to Plasmodium infection
of malaria, causing significant morbidity and mortality in South America. Pyrethroid chemical has been
used to control mosquitos. We analyzed the expression of trypsin-3 and phosrestin II genes implicated
to feeding and resistance to insecticides, immune response and ... more

Gene cloning; Pistillata-like; qRT-PCR; RACE kit; Sedirea japonica

Members of the pistillata-like (PI-like) subfamily of plant MADS-box genes play multiple roles in regulation of reproductive meristems and the specification of sepal and petal identities. However, the function of PI-like genes in the Sedirea japonica is largely unknown. In this study, a full-length of PI-like gene in Sedirea japonica (designated PI-like, GenBank No ... more

Abscisic acid; Coffea arabica; Gibberellic acid; qRT-PCR

During maturation in seeds, metabolic processes dependent on gene expression are controlled by hormones, including abscisic acid and gibberellin. These hormones determine dormancy or the capacity for germination in seeds and may have different expression levels in the endosperm and embryo of coffee seeds. We quantified gene expression in the biosynthetic pathway of ... more
