Abstract:
... In the last decade extensive research has focused on the development of dose–response relationships based on stomatal plant ozone uptake (phytotoxic ozone dose, POD). So far most work has concentrated on crops and forest trees. This study provides a flux-based dose–response function for timothy (Phleum pratense), a widespread grassland species, which can be used in risk assessment for ground-level ...

Abstract:
... For crops grown in Mediterranean environments, translocation of pre-anthesis assimilates to the fruit is of great importance, because hot and dry conditions during fruit ripening diminish net assimilation rate and nitrogen (N) uptake. This field study was conducted to assess the pattern of dry matter and N accumulation and the role of assimilate translocation in pod development of oilseed rape pla ...

Abstract:
... The soil-borne pathogenic fungus Verticillium dahliae Kleb. causes economic losses in crops in temperate regions of the world and hence is the most studied species. Strawberry (Fragaria x ananassa Duch.) belongs to plant species susceptible to Verticillium dahliae, although the response to infection caused by this pathogen is varied and depends on the cultivar. Due to a lack of efficient methods i ...

crops; dry matter partitioning; genetic variation; genotype; leaves; nitrogen; nitrogen content; nutrient use efficiency; nutritional status; plant breeding; root systems; roots; stems; tillering; wheat
Abstract:
... Improving arable crops nitrogen use efficiency (NUE) is a major target of plant breeding. In wheat, a large part of the nitrogen (N) harvested in the grain originates from N remobilization from vegetative organs during the post-anthesis period. While N remobilization from above-ground organs such as leaves and stems has been extensively studied, studies about N remobilization from roots are scarce ...

BACKGROUND: Grafting is widely used in the agriculture of fruit-bearing crops; rootstocks are known to confer differences in scion biomass in addition to improving other traits of agricultural interest. However, little is known about the effect of rootstocks on scion gene expression. The objective of this study was to determine whether hetero-grafting the grapevine variety Vitis vinifera cv. 'Cabe ...

Plant architectural traits have been reported to impact pest and disease, i.e., attackers, incidence on several crops and to potentially provide alternative, although partial, solutions to limit chemical applications. In this paper, we introduce the major concepts of plant architecture analysis that can be used for investigating plant interactions with attacker development. We briefly review how p ...

Stay-green is a term that is used to describe mutant and transgenic plants or cultivars with the trait of maintaining their leaves for a longer period of time than the wild-type or crosses from which they are derived. Analyzing stay-green genotypes contributes to our understanding of the molecular me ...

Abstract:
... Soybean (Glycine max [L.] Merr.) N2 fixation is a primary plant mechanism responsible for meeting plant-N demand during seed development. Nitrogen fixation is recognized as a drought-sensitive mechanism; however, N2 fixation response to water deficit and N2 fixation recovery at different reproductive stages are not well documented. We tested the hypothesis that water deficit during late reproducti ...
