Worldwide, extensive agricultural losses are attributed to drought, often in combination with heat Mediterranean climate regions, where grapevine traditionally grows. The available scenarios for change suggest increases aridity these regions. Under natural conditions plants affected by a of stresses, triggering synergistic or antagonistic physiological, metabolic transcriptomic responses unique the combination. However study such stresses controlled environment can elucidate important...
Grapevine (Vitis vinifera L.) diversity richness results from a complex domestication history over multiple historical periods. Here, we used whole-genome resequencing to elucidate different aspects of its recent evolutionary history. Our support model in which central event grapevine was followed by postdomestication hybridization with local wild genotypes, leading the presence an introgression signature modern wine varieties across Western Europe. The strongest signal associated subset...
DNA methylation is thought to influence Quercus suber cork quality, which the main constraint for its economic valorisation. However, a deep knowledge of cytosine patterns disclosing epigenetic variability trees with different quality types totally missing. This study investigates hypothesis that variations in contribute differences cellular characteristics directly related original or traumatic phellogen activity. We used MSAPs (Methylation Sensitive Amplified Polymorphism) assess and leaf...
There are thousands of ancient grapevine varieties in Europe, each one having a high level intra-varietal diversity with regard to important economic traits (yield, soluble solids content, acidity, anthocyanins, and others). However, this potential has become exposed process genetic erosion since the middle last century. The main objective work is present experimental strategies for conservation utilization diversity. A concrete example given about actions performed Portugal 1978. Two...
Background and Aims The evaluation of genotype-by-environment interaction the genotypic correlations between important economic traits are two relevant issues methodology grapevine selection that remain insufficiently explored. aim this study is to provide methodological tools to: (i) assess (ii) evaluate genetic their practical impacts on selection. Methods Results A multi-environment analysis for each trait multi-trait analyses were applied correlation pairs traits, respectively. presence...
Heat stress negatively affects several physiological and biochemical processes in grapevine plants. In this work, two new methods, calorespirometry, which has been used to determine temperature adaptation plants, near-infrared (NIR) spectroscopy, grapevine-related traits discriminate among varieties, were tested evaluate response high temperatures. ‘Touriga Nacional’ variety grapevines, inoculated or not with Rhizoglomus irregulare Funneliformis mosseae, study. Calorespirometric parameters...
Clonal selection allows control of virus diseases and genotypes on agronomic, viticultural or enological criteria. has the major drawback that it impoverishes genetic diversity exposes growers to environmental instability clones (genotype X environment interaction). become almost unique way propagating plant material for vineyards, hence threatening grapevine. For grapevine varieties, some is maintained in institutional collections. However, this conservation insufficiently developed,...
The genetic diversity accumulated over centuries within ancient grapevine cultivars is the raw material for any selection. greater intravarietal variability, will be gains obtainable from selection and capacity of cultivar to respond present future challenges a viticulture in which growing valued. Therefore, it should efficiently evaluated, involves establishment field trials with powerful experimental designs fitting appropriate models data analysis. key point perform well-planned accurate...
Background and Aims The development of an efficient clonal selection process requires the study genotype-by-environment (G × E) interaction. This work aims to evaluate variability G E interaction among genotypes identify less sensitive ones. Methods Results approach involves fitting mixed models yield data taking into account correlation induced by repeated measurements same plot over years. A measure for comparative evaluation is proposed [Interaction Sensitivity (IS)], based on variance...
High temperatures and extreme drought are increasingly more frequent in Portugal, which represents a strong threat to viticulture certain regions of the country. These multifactorial abiotic stresses threatening viticultural areas worldwide, problem can hardly be overcome only by changing cultural practices. This scenario has raised major challenge for plant scientists find ways adapt existing varieties new conditions without loss their characteristic flavors, yield, associated varietal...
