Morinda citrifolia L., commonly known as noni, has been used for the treatment of various diseases for over two centuries. It was introduced and widely disseminated in Brazil because of its high market value and ease of adaptation to the soil and climatic conditions of the country. The aim of this study was to estimate the genetic variability of noni accessions from the collection of Embrapa ... more

The strawberry (Fragaria x ananassa Dutch.), is the only vegetable belonging to the rosacea family. All strawberry species have now emerged from wild species and belong to the genus Fragaria, being that this genus presents more than 45 described species, and only 11 are considered natural species. Due to the octoploid nature of strawberry and its variability after hybridization, selecting one ... more

Chinese cabbage is an important cruciferous vegetable in China. The differences in the morphology and other characteristics of the different varieties of Chinese cabbage are generally caused by their different genes. Using the simple sequence repeat (SSR) DNA molecular markers is an effective way to identify different genotypes. The identification of a genetic relationship is a key point in ... more

In vitro studies have shown that multidrug resistance protein 1 (MDR1) has an affinity for cortisol; however, in vivo association studies on the relationship between MDR1 gene polymorphisms and blood cortisol levels have produced inconsistent results. Therefore, we examined the effects of the C3435T polymorphism of the MDR1 gene on blood levels of hypothalamus-pituitary-adrenal (HPA) axis ... more

Human blood groups are a significant resource for patients, leading to a fierce international competition in the screening of rare blood groups. Some rare blood group screening programs have been implemented in western countries and Japan, but not particularly in China. Recently, the genetic background of ABO and Rh blood groups for different ethnic groups or regions in China has been focused ... more

Doubling method is the technical barriers in maize haploid breeding. It was very important to establish the independent intellectual property rights for doubling method. In this experiment, the maize haploid inducer, TG15, was used for producing maternal haploids. Also, haploids were obtained from two kinds of maternal genotypes involved in the experiment, including high-oil type and common ... more

Digital image analysis of seeds has been used for the identification of cultivars, determination of seed color and mechanical damage, and classification of different seed sizes. The aim of the present study was to evaluate the efficiency of digital image analysis of seeds for the quantification of genetic diversity among genotypes of inbred guava (Psidium guajava L.) families. The SAS Mini ... more

The development of common bean cultivars with high technological quality that are biofortified with minerals, is required to meet the demand for food with health benefits. The objectives of this study were to evaluate whether common bean genotypes differ in terms of technological and mineral biofortification traits, to study the correlations between these characters, to analyze the genetic ... more

Jatropha is research target worldwide aimed at large-scale oil production for biodiesel and bio-kerosene. Its production potential is among 1200 and 1500 kg/ha of oil after the 4th year. This study aimed to estimate combining ability of Jatropha genotypes by multivariate diallel analysis to select parents and crosses that allow gains in important agronomic traits. We performed crosses in ... more

Atherosclerosis is characterized by lesions, called atheroma or atheromatous plaques, in the inner layer of blood vessels, which block the vascular lumen and weaken the underlying tunica media. Several modifiable and non-modifiable risk factors for the development of atherosclerosis exist. The modifiable risk factors include hypertension, smoking, obesity, high LDL and low HDL cholesterol ... more
