The Colombian Central Collection of potatoes (CCC) is one of the most diverse germplasm resources in the country and a primary source of genetic variability for breeding. Approximately 67% of its accessions belong to the Andigenum group, which exhibits remarkable color diversity and associated nutraceutical potential. However, the genetic architecture of the color traits in this group remains poorly understood. In this study,...
Detection of downy mildew infection in grapevine leaves using field spectroscopy and machine learningNARA Subscribed
Context Downy mildew, caused by Plasmopara viticola , remains one of the most damaging diseases affecting grapevines, especially in humid viticultural regions such as the “Vinhos Verdes” in northern Portugal. Traditional detection relies on visual inspection and laboratory techniques, which are subjective and reactive, often delaying effective intervention. Aims This study aims to evaluate the potential of field spectroscopy c...
Peanut smut, caused by the soilborne pathogen Thecaphora frezzii , poses a significant threat to Argentina’s peanut production. As a monocyclic disease, the infections are restricted to pegs and pods, with no direct plant-to-plant spread. Spore dissemination occurs exclusively during harvest when infected pods release spores, which can persist in the soil for many years. The lack of detailed knowledge about the spatial pattern...
Future agroclimatic suitability for oliviculture in Portugal based on a new high-resolution climate datasetNARA Subscribed
The Mediterranean-type climates on mainland Portugal generally provide suitable conditions for growing olive trees, though climate change may challenge their long-term sustainability. Historical (1995–2014) and projected future scenarios (2041–2060) of agroclimatic indices are developed herein to guide olive orchard (OR) management. Daily simulations from six Global Circulation Models are processed with the CHELSA method, usin...
Priority effects, where the order and timing of species arrival influence the assembly of ecological communities, have been observed in a variety of taxa and habitats. However, the genetic and molecular basis of priority effects remains unclear, hindering a better understanding of when priority effects will be strong. We sought to gain such an understanding for the nectar yeast Metschnikowia reukaufii commonly found in the nec...
