Orange rust, caused by the fungus Puccinia kuehnii, results in high productivity losses in sugarcane. Selection of resistant genotypes is one of the aims of sugarcane breeding programs. Phenotypic and molecular characterization of the parents of such crosses is essential to obtain superior varieties. We evaluated the reaction to orange rust in the field, ... more

Wheat is considered a basic cereal for civilization with great economic importance for world agriculture. Currently, wheat is planted in the south, southeast and midwest regions of Brazil. Brazilian consumption of wheat will grow in the coming years due to population increase, which will require developing new cultivars for non-tradtional regions. We investigated ... more

The most common type of endocrine disease is type 2 diabetes mellitus (T2DM); genetic factors contribute to the development to T2DM. In this study, we investigated the role of the Leu53Leu, Arg213Gly, and Ala40Thr polymorphisms in extracellular superoxide dismutase (EC-SOD) gene in the development of T2DM in a Chinese population. DNA was extracted from peripheral blood samples obtained from ... more

We conducted a case-control study to investigate the association between the interleukin-10 (IL-10) C819T polymorphism and susceptibility to gastric cancer in a Chinese population. A total of 157 patients with gastric cancer and 249 controls were consecutively enrolled from the Guizhou Provincial People's Hospital between October 2012 and February 2015. The polymerase chain reaction- ... more

Trichomes are derived from the epidermis and constitute an ideal system for studying cell division in plants. Here, a Chinese cabbage doubled haploid (DH) line (FT) without trichomes was crossed with another DH line (PurDH-1) with trichomes to develop an F population for fine mapping of trichome control genes. Genetic analysis showed that the trichome phenotype was controlled by a single ... more

Lifeguard is an integral transmembrane protein that modulates FasL-mediated apoptosis by interfering with the activation of caspase 8. It is evolutionarily conserved, with homologues present in plants, nematodes, zebra fish, frog, chicken, mouse, monkey, and human. The Lifeguard homologue in Drosophila, CG3814, contains the Bax inhibitor-1 family motif of unknown function. Downregulation of ... more

Rice (Oryza sativa L.) blast disease is one of the most destructive rice diseases in the world. The fungal pathogen, Magnaporthe oryzae, is the causal agent of rice blast disease. Development of resistant cultivars is the most preferred method to achieve sustainable rice production. However, the effectiveness of resistant cultivars is hindered by the genetic plasticity of the pathogen genome. ... more

The multivariate analyses are useful tools to estimate the genetic variability between accessions. In the breeding programs, the Ward-Modified Location Model (MLM) multivariate method has been a powerful strategy to quantify variability using quantitative and qualitative variables simultaneously. The present study was proposed in view of the dearth of information about popcorn breeding ... more

Two cassava escapes where collected from cultivated fields near natural habitat in Bolivia. They are described morphologically and analyzed cytogenetically in this study. It is suggested that they are the product of backcrosses of cassava interspecific hybrids with the cultigen itself, and that selective conditions have developed in which certain forms of cassava segregates have adapted to ... more

Studying genetic diversity among a group of genotypes is important in genetic breeding because identifying hybrid combinations of greater heterotic effect also increases the chance of obtaining plants with favorable allele combinations in an intra-population selection program. The objective of this study was to compare different types of long and extra-long staple cotton and their genetic ... more
