Summary Genetic maps are key tools in genetic research as they constitute the framework for many applications, such quantitative trait locus analysis, and support assembly of genome sequences. The resequencing two parents a cross between E ucalyptus urophylla grandis was used to design single nucleotide polymorphism ( SNP ) array 6000 markers evenly distributed along . genome. genotyping 1025 offspring enabled construction high‐resolution containing 1832 1773 with an average marker interval...
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....
Wood is one of our most important natural resources. Surprisingly, we know hardly anything about the details process wood formation. The aim this work was to describe main proteins expressed in forming tissue a conifer species (Pinus pinaster Ait.). Using high resolution 2-DE with linear pH gradient ranging from 4 7, total 1039 spots were detected. Out 240 analyzed by MS/MS, 67.9% identified, 16.7% presented no homology databases, and 15.4% corresponded protein mixtures. 57 MALDI-MS, only...
Hepatocellular carcinoma (HCC) is a major complication of chronic viral hepatitis C. Therapy for HCC still disappointing. It thus great importance to identify novel markers early detection the disease, and tumor-specific proteins as potential therapeutic targets. We have used proteomic approach new involved in development. Four cases developing from C were analyzed by two-dimensional electrophoresis (2-DE), results compared those paired adjacent non-tumorous liver tissues. For MS...
Eucalyptus is an important genus in industrial plantations throughout the world and grown for use as timber, pulp, paper charcoal. Several breeding programmes have been launched worldwide to concomitantly improve growth performance wood properties (WPs). In this study, interspecific cross between urophylla E. grandis was used identify major genomic regions (Quantitative Trait Loci, QTL) controlling variability of WPs.Linkage maps were generated both parent species. A total 117 QTLs detected...
Abstract Background The availability of a large expressed sequence tags (EST) resource and recent advances in high-throughput genotyping technology have made it possible to develop highly multiplexed SNP arrays for multi-objective genetic applications, including the construction meiotic maps. Such approaches are particularly useful species with genome size, precluding use whole-genome shotgun assembly current technologies. Results In this study, 12 k-SNP array was developed maritime pine...
Abstract Maritime pine provides essential ecosystem services in the south‐western M editerranean basin, where it covers around 4 million ha. Its scattered distribution over a range of environmental conditions makes an ideal forest tree species for studies local adaptation and evolutionary responses to climatic change. Highly multiplexed single nucleotide polymorphism ( SNP ) genotyping arrays are increasingly used study genetic variation living organisms practical applications plant animal...
Meiotic recombination is a fundamental evolutionary process. It not only generates diversity, but influences the efficacy of natural selection and genome evolution. There can be significant heterogeneity in rates within between species, however this variation well understood outside few model taxa, particularly forest trees. Eucalypts are trees global economic importance, dominate many Australian ecosystems. We studied rate Eucalyptus globulus using genetic linkage maps constructed 10...
Abstract Background The genetic basis of growth traits has been widely studied in forest trees. Quantitative trait locus (QTL) studies have highlighted the presence both stable and unstable genomic regions accounting for biomass production with respect to tree age background, but results remain scarce regarding interplay between QTLs environment. In this study, our main objective was dissect architecture trajectory emphasis on genotype x environment interaction by measuring primary secondary...
Summary In the context of climate change, water‐use efficiency ( WUE ) highly productive tree varieties, such as eucalypts, has become a major issue for breeding programmes. This study set out to dissect genetic architecture carbon isotope composition (δ 13 C ), proxy , across several environments. A family E ucalyptus urophylla × . grandis was planted in three trials and phenotyped δ growth traits. High‐resolution maps enabled us target genomic regions underlying quantitative trait loci QTL...
Selection was conducted on an index of components litter size (I = 1.21 × ovulation rate + 9.05 ova success; measured by number corpora lutea and success as pups born lutea), uterine capacity (measured to unilaterally ovariectomized dams) concurrent with unselected control for 13 generations. criteria (IX index, UT capacity, LS LC control) were applied in each three replicates. In evaluation after five generations, IX exceeded about .5 pups, no response UT. After mean rate, fetuses at 17 d...
To better understand the genetic control of secondary xylem formation in trees we analysed genes expressed during Eucalyptus development. Using eucalyptus cDNA libraries, identified EgROP1, a member plant ROP family Rho-like GTPases. These signalling proteins are central regulators many important processes plants, but information on their role xylogenesis is scarce. Quantitative real-time reverse-transcriptase polymerase chain reaction (qRT-PCR) confirmed that EgROP1 was preferentially...
Summary The pulse of the tree (diurnal cycle stem radius fluctuations) has been widely studied as a way analyzing responses to environment, including phenotypic plasticity tree–water relationships in particular. However, genetic basis this daily phenotype and its interplay with environment remain largely unexplored. We characterized environmental determinants response, by monitoring fluctuation (dSRF) on 210 trees from Eucalyptus urophylla × E. grandis full‐sib family over 2 years. dSRF...
