Abiotic stress; Agrostis stolonifera; AsACO; Ethylene biosynthesis

A gene encoding 1-aminocyclopropane-1-carboxylic oxidase (ACO), which catalyzes the terminal step in ethylene biosynthesis, was isolated from Agrostis stolonifera. The AsACO gene is composed of 975 bp, encoding 324 amino acids. Three exons interspersed by two introns form AsACO gDNA. A BLAST search of the nucleotide sequence revealed a ... more

Artificial Intelligence; Genotype x environment interaction; Vigna unguiculata

Cowpea (Vigna unguiculata) is grown in three Brazilian regions: the Midwest, North, and Northeast, and is consumed by people on low incomes. It is important to investigate the genotype x environment (GE) interaction to provide accurate recommendations for farmers. The aim of this study was to identify cowpea genotypes with high adaptability and phenotypic ... more

Cotton; Fiber; Predicted gains

Brazil is among the five largest producers of cotton in the world, cultivating the species Gossypium hirsutum L. r. latifolium Hutch. The cultivars should have good fiber quality as well as yield. Genetic improvement of fiber traits requires the study of the genetic structure of the populations under improvement, ... more

Aggressiveness; Differentiating series; Genetic resistance; Partial diallels; Physiological races

Bacterial wilt of common bean caused by Curtobacterium flaccumfaciens pv. flaccumfaciens is an important disease in terms of economic importance. It reduces grain yield by colonizing xylem vessels, subsequently impeding the translocation of water and nutrients to the superior plant parts. The existence of physiological ... more

Gain from selection; Heritability; Phaseolus vulgaris; Simultaneous selection

Slow seed coat darkening is desirable in common bean cultivars and genetic parameters are important to define breeding strategies. The aims of this study were to estimate genetic parameters for plant architecture, grain yield, grain size, and seed-coat darkening in common bean; identify any genetic association among these traits; and select lines that associate ... more

Common bean cultivars; Cycle stability; Flowering stability; Grain yield; Phaseolus vulgaris; Plant architecture

The objective of this study was to select common bean cultivars based on their stability for flowering, cycle, insertion of the first pod, grain yield, and high agronomic performance. Twenty experiments were carried out between 2000 and 2014, during two growing seasons, in Rio Grande do Sul, Brazil. The Eberhart and Russel, and Lin and Binns methods, as well as the ... more

Calculating study sample size; Experimental precision; Sampling; Zea mays L.

Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize genotypes and to verify the ... more

Ligninolytic enzymes; Mycelial growth; Polyphenol oxidase; White-rot fungi

Fungus ability to respond to environmental changes allows their adaptation to a wide variety of conditions such as pH, temperature, light, nutrient availability, chemicals, and competition among species. Temperature and pH can affect fungal growth as well as their metabolism. Knowing these factors on fungus species is relevant for the development of ... more

Genetic diversity; Marker-trait association; Population structure; SSR marker; Waxy and normal maize inbred line

Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (SSR) markers. Based on a population ... more

Bacterial artificial chromosome library; Drought tolerance; Gossypium tomentosum; SSR marker; Verticillium wilt resistance; Wild cotton

Gossypium tomentosum is a wild allotetraploid species with the (AD)5 genome. It is characterized by many useful traits including finer fiber fineness, drought tolerance, and Fusarium and Verticillium resistance. We constructed the first bacterial artificial chromosome library for Gossypium tomentosum. With high quality and broad coverage, ... more
