A broad-scale analysis of the main factors determining the current structure and understory composition of Catalonian sub-alpine (Pinus uncinata Ram.) forests
(Oxford University Press, 2011-12-13)A broad-scale analysis of the structure and understory composition of Pyrenean mountain pine (Pinus uncinata Ram.) stands was performed using data from the Spanish National Forest Inventory. Twelve structure-based forest ... -
A carotenogenic mini-pathway introduced into white corn does not affect development or agronomic performance
(Nature, 2016)High-carotenoid corn (Carolight®) has been developed as a vehicle to deliver pro-vitamin A in the diet and thus address vitamin A deficiency in at-risk populations in developing countries. Like any other novel crop, the ... -
A distinct, non-virion plant virus movement protein encoded by a crinivirus essential for systemic infection
(American Society for Microbiology, 2018)Plant-infecting viruses utilize various strategies involving multiple viral and host factors to achieve successful systemic infections of their compatible hosts. Lettuce infectious yellows virus (LIYV), genus Crinivirus, ... -
A golden era—pro-vitamin A enhancement in diverse crops
(Springer Verlag, 2011)Numerous crops have been bred or engineered to increase carotenoid levels in an effort to develop novel strategies that address vitamin A deficiency in the developing world. The pioneering work in rice (not covered in ... -
A mixed-effects model with different strategies for modeling volume in cunninghamia lanceolata plantations
(Public Library of Science, 2015)A systematic evaluation of nonlinear mixed-effect taper models for volume prediction was performed. Of 21 taper equations with fewer than 5 parameters each, the best 4-parameter fixed-effect model according to fitting ... -
A new family of standardized and symmetric indices for measuring the intensity and importance of plant neighbour effects
(Wiley, 2016)1. Measurements of competition and facilitation between plants often rely upon intensity and importance indices that quantify the net effect of neighbours on the performance of a target plant. A systematic analysis of the ... -
A novel carotenoid, 4-keto-a-carotene, as an unexpected by-product during genetic engineering of carotenogenesis in rice callus
(Elsevier, 2014)Rice endosperm is devoid of carotenoids because the initial biosynthetic steps are absent. The early carotenogenesis reactions were constituted through co-transformation of endosperm-derived rice callus with phytoene ... -
A priori parameterisation of the CERES soil-crop models and tests against several European data sets
(Institut national de la recherche agronomique (França)EDP Sciences, 2002)Mechanistic soil-crop models have become indispensable tools to investigate the effect of management practices on the productivity or environmental impacts of arable crops. Ideally these models may claim to be universally ... -
A question of balance: achieving appropriate nutrient levels in biofortified staple crops
(Cambridge University Press, 2013)The biofortification of staple crops with vitamins is an attractive strategy to increase the nutritional quality of human food, particularly in areas where the population subsists on a cereal-based diet. Unlike other ... -
A reduced growth model based on stand basal area. A case for hybrid poplar plantations in northeast Spain
(Elsevier, 2010)Whole-stand models normally require data on initial stand basal area and dominant height. Dominant height measurements are time-consuming and often imprecise, compromising subsequent predictions. Poplar plantations provide ... -
A resource-based modelling framework to assess habitat suitability for steppe birds in semiarid mediterranean agricultural systems
(Public Library of Science (PLoS), 2014)European agriculture is undergoing widespread changes that are likely to have profound impacts on farmland biodiversity.The development of tools that allow an assessment of the potential biodiversity effects of different ... -
A retrospective, dual-isotope approach reveals individual predispositions to winter-drought induced tree dieback in the southernmost distribution limit of Scots pine
(John Wiley & Sons Ltd, 2013)Winter-drought induced forest diebacks in the low-latitude margins of species’ distribution ranges can provide new insights into the mechanisms (carbon starvation, hydraulic failure) underlying contrasting tree reactions.We ... -
A roadmap to disentangling ecogeographical patterns of spatial synchrony in dendrosciences
(Springer Verlag, 2017-12-30)The concept of spatial synchrony in ecology refers to the presence of coordinated time fluctuations in certain characteristics that can be observed in plant and animal communities inhabiting an area. It is a well-known ... -
A survey of potential vectors of apricot chlorotic leaf roll
(Institut national de la recherche agronomique (França)EDP Sciences, 1988)A comparative survey was done in leafhopper populations captured in apricot orchards in two areas of Valencia, one with considerable natural spread of apricot chlorotic leaf roll (ACLR), and the other where such natural ... -
A Thioredoxin Domain-Containing Protein Interacts with Pepino mosaic virus Triple Gene Block Protein 1
(MDPI, 2018)Pepino mosaic virus (PepMV) is a mechanically-transmitted tomato pathogen of importance worldwide. Interactions between the PepMV coat protein and triple gene block protein (TGBp1) with the host heat shock cognate protein ... -
A trade-off between embolism resistance and bark thickness in conifers: Are drought and fire adaptations antagonistic?
(Taylor & Francis, 2018)Background: Understanding the mechanisms that explain the spatial distribution of conifers across biogeographical gradients is important for anticipating potential range shifts owing to global change. Classical explanations ... -
Abundance of non-target pests in transgenic Bt-maize: a farm scale study
(Czech Academy of Sciences. Institute of Entomology of the Biology Centre, 2005)The impact of transgenic Bt-maize, expressing the Cry1Ab protein, on aphids, leafhoppers, cutworms and wireworms was evaluated at the farm scale by comparing their abundance on Bt-plots and those sown with the isogenic ... -

Aged but withstanding: Maintenance of growth rates in old pines is not related to enhanced water-use efficiency
(Elsevier, 2017-05-03)Growth of old trees in cold-limited forests may benefit from recent climate warming and rising atmospheric CO2 concentrations (ca) if age-related constraints do not impair wood formation. To test this hypothesis, we studied ...
