Phenotypic and genotypic correlations of agronomic traits with resistance to phytopathogens can help identify indirect selection criteria for corn yield. The Brazilian corn cultivar NAP5 is resistant to leaf spot and blight disease, while NAP7 is resistant to rust disease. Trials were conducted in two states from February to July 2015. The following traits were ... more
One of the pests that infests the corn crop (Zea mays) in Brazil is the fall armyworm (Spodoptera frugiperda, Lepdoptera: Noctuidae), considered its most important pest because of the significant damage produced. The use of resistant cultivars is an efficient control method. The objective of this work was to evaluate the mechanisms of resistance ... more
There is a lack of information regarding variables that regulate the expression of the yield potential of maize. We studied yield components of maize under different arrangements on field, in the southwest region of the state of Goiás, Brazil. The soil of the experimental area is classified as Typic Orthotic. The experimental design was randomized blocks, in a 9x2 ... more
The corn leafhopper, Dalbulus maidis, is the most important pest of maize (Zea mays) in the Neotropics, due to its efficiency in pathogen transmission and close evolutionary association with the crop. This host specialization has enabled D. maidis to spread with maize, from their center of origin in Mesoamerica to all tropical and ... more
The present study clearly showed that chronic exposure to polychlorinated biphenyls (PCBs) at environmentally relevant concentrations can damage juvenile tilapia livers by modulating antioxidant enzyme activities and gene transcription, which affects toxic bioaccumulation and histological congestion. The results suggest that PCBs caused a decrease in the activity of some hepatic ... more
Anthocyanins are flavonoids compounds that have a great therapeutic potential acting as antioxidants, anti-inflammatory and anti-carcinogenic agents. They are consumed through food, pharmaceutical and cosmetics industries as a natural alternative to synthetic dyes. However, anthocyanins are unstable depending on pH, temperature, light and oxygen variations, which ... more
Apricot is a staple stone fruit crop cultivated in Southern Xinjiang of China. This crop is important for the rural communities, as they generate significant employment and income. Here, seventy-eight apricot genotypes, including seventy-six common apricots (Prunus armeniaca L.) and two purple apricots (Prunus dasycarpa Ehrh.), were mainly collected from Aksu, ... more
Bovine papillomavirus (BPV) is an oncogenic virus with mucous and epithelial tropism. Possible productive virus infection in other tissues, such as blood, has been hypothesized. In order to investigate this possibility, three samples of skin papillomas and blood were collected from bovines with BPV infection and five samples of peripheral blood and one sample of normal tissue were collected ... more
The bovine papillomavirus (BPV) causes papillomas that regress spontaneously, but can also progress to malignancy. This study evaluated the role of BPV in oncogenesis. Twenty-four samples from uninfected calves and the papillomas of BPV infected cattle were subjected to molecular diagnosis, as well as histopathological and immunohistochemical analyses. The comet assay (CA) was used to ... more
Biomonitoring of air quality using living organisms is a very interesting approach to environmental impact assessment. Organisms with a vast distribution, such as plants, are widely used for these purposes. The castor bean (Ricinus communis L.) is an oleaginous plant that can potentially be used as a bioindicator plant owing to its rapid growth and large leaves, which have a wide ... more
