A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos
(BioMed Central, 2019-07-04)Background: The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been ... -
A dynamic model for sodium intoxication unravels salt tolerance in grapevine (Vitis vinifera L.) rootstocks
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12)A correct selection of salt-tolerant plants should consider the relative effects of the various existing tolerance mechanisms. When toxic ions, like Na+, reach the leaves, they affect the photosynthetic apparatus, reducing ... -
A fijivirus major viroplasm protein shows RNA-stimulated ATPase activity by adopting pentameric and hexameric assemblies of dimers
(American Society for Microbiology, 2023-02)Fijiviruses replicate and package their genomes within viroplasms in a pro cess involving RNA-RNA and RNA-protein interactions. Here, we demonstrate that the 24 C-terminal residues (C-arm) of the P9-1 major viroplasm protein ... -
A first record of bulk atmospheric deposition patterns of major ions in southern South America
(Springer, 2019-09)Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long record of atmospheric ... -
A first worldwide multispecies survey of invasive Mediterranean pine bark beetles (Coleoptera: Curculionidae, Scolytinae)
(Springer, 2020-02)Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring ... -
A Framework to tackling the synchrony between Social and Ecological phases of the annual cyclic movement of transhumant pastoralism
(MDPI, 2020-04)Transhumant pastoralism is mobile livelihood strategy in which families and their herds move seasonally from lowlands, where they settle during the winter, towards the highlands, located in mountainous areas, during the ... -
A functional classification of 63 common Poaceae in the “Campos” grasslands of South America
(Asociación Argentina de Ecología, 2019-08)The natural grasslands that form part of the “Campos” of South America contain a large number of species at the paddock level (high α diversity), but little differentiation among paddocks (low β diversity). Thus, forage ... -
A functional XopAG homologue in Xanthomonas fuscans pv. aurantifolii strain C limits host range
(British Society for Plant Pathology, 2015)Citrus canker is caused by two Xanthomonas species, Xanthomonas citri, which has become the primary pathogen where citrus canker occurs (type A citrus canker, Xc-A), and X. fuscans pv. aurantifolii (Xfa), which consists ... -
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ... -
A fungal endophyte of a palatable grass affects preference of large herbivores
(2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
A fungal protease named AsES triggers antiviral immune responses and effectively restricts virus infection in arabidopsis and Nicotiana benthamiana plants
(Oxford University Press, 2022-04)Background and Aims: Plants have evolved complex mechanisms to fight against pathogens. Among these mechanisms, pattern-triggered immunity (PTI) relies on the recognition of conserved microbe- or pathogen-associated molecular ... -
A fűszerpaprika (capsicum annuum l.) termesztése és földolgozása Argentínában [El pimiento picante (Capsicum annuum L.) cultivado y procesado en Argentina]
(Sigillum 2000, 2020)A fűszerpaprika termesztése Argentínában két fő körzetben, Mendoza környékén, valamint északon Tucumán, Catamarca és Salta tartományok határvidékén koncentrálódik. Az étkezési paprikához képest sokkal kisebb a jelentősége, ... -
A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation
(2014-12)Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits. Informative, saturated linkage ... -
A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
A genome-wide association study unveils key chromosome regions involved in determining sodium accumulation in wheat under conditions of low potassium supply
(Elsevier, 2022-05-30)Improving nutrient use efficiency is an important objective in modern breeding programs. In this work, we examined potassium utilization efficiency (KUtE) and traits potentially related to it in a formerly genotyped, ... -
