Article
Full-text available
Drought can increase nitrogen (N) loss due to enhanced asynchronicity between N release through mineralization and plant N uptake. Organic amendments of N could potentially mitigate this loss where the N is more slowly released and made available at times when plants need it. Drought (ambient vs. reduced precipitation implemented with rainout shelt...
Article
The quantity and chemical composition of soil organic carbon (C) are primary factors controlling the growth and activity of soil microorganisms. However, availability of phosphorus (P) can also limit microbial activity as it is required for the synthesis of genetic and cellular components, metabolism and energy transfer. Little is known about how P...

Living roots can influence microbial decomposition of soil organic matter, which has been referred to as the rhizosphere priming effect (RPE). Both microbial carbon efficiency (CUE) and microbial growth and turnover rates are associated with microbial decomposition and respiration of soil-derived C, but their linkage to the RPE remains poorly under...
Article
Drought and high temperature are major environmental stress factors threatening wheat production during grain filling stage resulting in substantial yield losses. Four wheat genotypes (Suntop, IAW2013, Scout and 249) were planted under two temperature levels (25 and 30°C) and two water levels (15% and 25% soil moisture content). Wheat yield, leaf δ...
Article
The ability of plants to access water and nutrients is a key aspect of crop production and it is mainly through modified root growth that plants can optimize their access to those resources. Although genetics play a main role in shaping root traits, other factors such as soil physical characteristics and the distribution of water and nutrients in t...
Article
Identifying root traits that are associated with efficient nutrient and water utilization is crucial for improving plant functioning and productivity. In the case of wheat genotypes, such root traits could be used by plant breeders to improve grain yield and quality. In this study 23 wheat genotypes (Triticum spp.) belonging to different breeding g...
Article
Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes (IAW2013 and 249) were planted after crop rotation with canola or chickpea with different nit...
Article
Background and aims Water and nitrogen are essential for plant growth and yield. Plants depend on surface roots for nutrient uptake, but frequently rely on deep root systems for water uptake, especially in semi-arid, rain fed crop production systems. Methods We used H218O and 15NH4+ tracers in pots to determine water and NH4+ uptake at depth by two...
Article
Background and aims Understanding the effect of wheat genotype on soil properties will be crucial in breeding towards more sustainable wheat production and increased yield. We examined the relationships between root traits, soil properties and grain yield for 24 wheat genotypes grown under field conditions. Methods Wheat genotypes (Triticum spp.) w...

Changes in the soil microbial community structure can lead to dramatic changes in the soil ecosystem. Temperature, which is projected to increase with climate change, is commonly assumed to affect microbial communities, but its effects on agricultural soils are not fully understood. We collected soil samples from six vineyards characterised by a di...

Background and aims Vineyards harbour a variety of weeds, which are usually controlled since they compete with grapevines for water and nutrients. However, weed plants may host groups of fungi and bacteria exerting important functions. Methods We grew three different common vineyard weeds (Taraxacum officinalis, Trifolium repens and Poa trivialis)...
Article
Microbial communities living in nine vineyards distributed over three altitudinal transects were studied over two years. Fungal and bacterial community dynamics were explored using automated ribosomal intergenic spacer analysis (ARISA) and by determining bacterial cells and fungal colony-forming units (CFUs). Moreover extensive chemical and physica...

We studied the distribution of fungal endophytes of grapevine (Vitis vinifera L.) plants in a subalpine area of northern Italy, where viticulture is of high economic relevance. We adopted both cultivation-based and cultivation-independent approaches to address how various anthropic and nonanthropic factors shape microbial communities. Grapevine ste...
Article
The study of the interactions among microorganisms, especially between pathogens and other microorganisms, is a very useful way to identify possible biocontrol agents (BCAs). In this study we verified the capability of δ(13)C analysis using isotope ratio mass spectrometry (IRMS) to detect active parasitism or metabolic assimilation of (13)C-labeled...
Conference Paper
The concerns on climate change and in particular the increase of global temperature are inflaming the public debate among scientist in recent years, especially regarding the possible effect on environment, animals, plants and biodiversity. Microbial populations in soil are climate dependent. Changes in soil microbial population could influence plan...
