Abstract Background Benefits from high-throughput sequencing using 454 pyrosequencing technology may be most apparent for species with high societal or economic value but few genomic resources. Rapid means of gene sequence and SNP discovery this novel provide a set baseline tools genome-level research. However, it is questionable how effective the large numbers short reads essentially no prior information will support contig assemblies annotation. Results With purpose generating first broad...

Abstract Background In a context of climate change, phenotypic plasticity provides long-lived species, such as trees, with the means to adapt environmental variations occurring within single generation. eucalyptus plantations, water availability is key factor limiting productivity. However, molecular mechanisms underlying adaptation shortage remain unclear. this study, we compared responses two commercial hybrids during dry season. Both differ in productivity when grown under deficit....
A fundamental goal of systems biology is to identify genetic elements that contribute complex phenotypes and understand how they interact in networks predictive system response variation. Few studies plants have developed such networks, none examined their conservation among functionally specialized organs. Here we used genetical genomics an interspecific hybrid population the model hardwood plant Populus uncover transcriptional xylem, leaves, roots. Pleiotropic eQTL hotspots were detected...
Leaf morphology varies extensively among plant species and is under strong genetic control. Mutagenic screens in model systems have identified genes established molecular mechanisms regulating leaf initiation, development, shape. However, it not known whether this diversity across related to naturally occurring variation at these genes. Quantitative trait locus (QTL) analysis has revealed a polygenic control for shape different suggesting that loci discovered by mutagenesis may only explain...
Adventitious roots (AR) develop from tissues other than the primary root, in a process physiologically regulated by phytohormones. provide structural support and contribute to water nutrient absorption, are critical for commercial vegetative propagation of several crops. Here we quantified number AR, root architectural traits biomass cuttings pseudo-backcross population Populus deltoides trichocarpa. Quantitative trait loci (QTL) mapping whole-transcriptome analysis individuals with...
The role of natural selection in shaping patterns diversity is still poorly understood the Neotropics. We carried out first genome-wide population genomics study a Neotropical tree, Handroanthus impetiginosus (Bignoniaceae), sampling 75,838 SNPs by sequence capture 128 individuals across 13 populations. found evidences for local adaptation using Bayesian correlations allele frequency and environmental variables (32 loci 27 genes) complemented an analysis selective sweeps genetic hitchhiking...
Abstract Brazil has a long history of intensive silviculture with Eucalyptus species, mainly urophylla and E. grandis . However, breeding advances may reduce genetic diversity in bred populations. Nine microsatellite markers assessed wild improved populations , similarity nine widely planted clones. Four were evaluated: Flores, Timor-Leste, Timor other Islands, along three For one population analyzed. Results showed higher populations, possibly due to admixed composition from different...
Abstract The genotype × environment (G E) interaction is a prevalent phenomenon that can challenge breeding and cultivar recommendation but offers opportunities for gains when the best genotypes are identified recommended each site. In this study, conducted in eastern Minas Gerais, Brazil, 46 eucalypt hybrid clones had their wood volume evaluated at contrasting altitudes. experiments were planted four different locations, two high altitudes (> 1000 m asl) low (<350 asl), with complete...
Abstract Background Handroanthus impetiginosus (Mart. ex DC.) Mattos is a keystone Neotropical hardwood tree widely distributed in seasonally dry tropical forests of South and Mesoamerica. Regarded as the “new mahogany,” it second most expensive timber, logged species Brazil, currently under significant illegal trading pressure. The plant produces large amounts quinoids, specialized metabolites with documented antitumorous antibiotic effects. development genomic resources needed to better...
Microarrays have demonstrated significant power for genome-wide analyses of gene expression, and recently also revolutionized the genetic analysis segregating populations by genotyping thousands loci in a single assay. Although microarray-based approaches been successfully applied yeast several inbred plant species, their has not proven an outcrossing species with extensive diversity. Here we developed methods high-throughput such using pseudo-backcross progeny 154 individuals Populus...
Despite important biotic stresses to common bean, Anthracnose (ANT) and Angular Leaf Spot (ALS) can cause losses of up 80 % occur in more than 60 countries around the world. Genetic resistance is most sustainable strategy manage these diseases. Thus, we aimed (1) identify new SNP markers associated with ALS ANT loci elite bean lines, (2) provide a functional characterization DNA sequences containing identified markers. We evaluated inbred under field conditions, which represent germplasm...
The radiation of angiosperms led to the emergence vast majority today’s plant species and all our major food crops. Their extraordinary diversification occurred in conjunction with evolution a more efficient vascular system for transport water, composed vessel elements. physical dimensions these water-conducting specialized cells have played critical role angiosperm evolution; they determine resistance water flow, influence photosynthesis rate, contribute stature. However, genetic factors...
Zinc is one of the main micronutrients for all organisms. One defense mechanisms used by host includes sequestration metals in fungal metabolism, such as iron and zinc. There are several that maintain balance intracellular zinc supply. MicroRNAs effector molecules responses between pathogen host, favoring or preventing infection many microorganisms.

Staphylococcus saprophyticus is a Gram-positive and coagulase negative cocci that composes the skin microbiota can act as an opportunistic agent causing urinary tract infections, being more frequent in sexually active young women. The ability of pathogen to cause infection host associated its adhere cells survive immune defenses. In this work, we presented comparative proteomic profile three S. strains. It was possible characterize differences proteome content, specially related expression...
