Density; Population; Spacing; Zea mays

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

Disease resistance; Evolution; Expressed sequence tag-simple sequence repeat; Genetic diversity; Gossypium

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, potential exists to improve disease ... more

Disease resistance; Expressed sequence tag; Tomato; Tomato yellow leaf curl virus; Ty-2

Tomato yellow leaf curl virus is one of the main diseases affecting tomato production worldwide. Previous studies have shown that Ty-2 is an important resistance gene located between molecular markers C2_At2g28250 (82.3 cM) and T0302 (89.0 cM), and exhibits strong re­sistance to tomato yellow leaf curl virus in Asia. In this study, Ty-2 can­didate genes were subjected to ... more

Disease resistance; FUT1; Immune indexes; Polymorphism; Pudong White pig; TAP1

FUT1 and TAP1 have been identified as candidate genes that offer resistance against Escherichia coli F18 infection, with the AA genotype in FUT1 and the GG genotype in TAP1 conferring resistance. In order to confirm polymorphisms at FUT1 M307 and TAP1 G729, and evaluate their influence on immunity performance in Pudong White pigs, we ... more

Cleaved amplified polymorphic sequence markers; Disease resistance; Melon; Molecular marker; Sex determination

In this study, molecular markers were designed based on the sex determination genes ACS7 (A) and WIP1 (G) and the domain in the Fusarium oxysporum-resistant gene Fom-2 (F) in order to achieve selection of F. oxysporum-resistant gynoecious melon plants. Markers of A and F are cleaved amplified ... more

Asian rust; Disease resistance; Genetic analysis; Genetic inheritance; Resistance genetic mapping

The goal of this study was to study resistance inheritance in the soybean (Glycine max L.) accession PI 594767-A to the Phakopsora pachyrhizi isolate PPUFV02, and map the resistance gene(s) identified using microsatellite markers. Crosses between PI 594767-A and the susceptible cultivar ‘Conquista’ gave rise to the segregating subpopulations 26C-2 and 26C-5, which in the ... more

Common bean breeding; Disease resistance; Molecular markers; Phaseolus vulgaris; Progenies; Seed yield

Common beans are a key source of protein and are consumed daily by most of the Brazilian population. More than 70% of what is consumed in this country is classified as carioca beans, based on seed qualities and appearance. We evaluated progenies of carioca common beans of the Brazilian agriculture research agency (Embrapa) recurrent selection program. This ... more

Bone tumor; CYP1A1; Genetic susceptibility; Genotype; GSTM1

Tumor gene polymorphisms are often associated with individual susceptibility to genetic diseases. Cytochrome P4501A1 (CYP1A1) and glutathione S-transferase mu 1 (GSTM1) gene polymorphisms are closely related to the susceptibility of the body to chemical carcinogens in the environment. Therefore, we explored the relationship between CYP1A1 and GSTM1 gene ... more

Genotype; Hepatitis B virus; Sequence analysis

Hepatitis B virus genotype C (HBV/C) has the largest number of subgenotypes (C1-C16) that vary with geography and isolates. HBV/C prevails in Southeast Asia (C1, C5-C16), East Asia (C2), Oceania (C3), and Australia (C4). Suitable reference strains for different subgenotypes could greatly facilitate research into HBV/C, but unfortunately they are scarce. We retrieved 974 HBV/C full-length ... more

Genotype; Goat; Milk protein; Polymorphism; SDS-PAGE

This study evaluates the relationship between the genotype and milk protein components in goats. Milk samples were collected from cloned goats and normal white goats during different postpartum (or abortion) phases. Two cloned goats, originated from the same somatic line of goat mammary gland epithelial cells, and three sexually reproduced normal white goats with no genetic relationships ... more
