Abstract Aims Root exudates are known to shape microbial activities in the rhizosphere and be of fundamental importance for plant-soil-microbe-carbon–nitrogen interactions. However, it remains unclear how what extent amount composition root exudation affects denitrification. Methods In this study patterns denitrification enzyme activity three different grass species grown on two agricultural soils under soil water contents were investigated controlled conditions. Results We found that...
The present study was performed to elucidate the fate of carbon (C) and nitrogen (N) derived from protein prey caught by carnivorous Dionaea muscipula. For this, traps were fed 13 C/15 N-glutamine (Gln). release CO2 continuously monitored isotope ratio infrared spectrometry. After 46 h, allocation C N label into different organs determined tissues subjected metabolome, proteome transcriptome analyses. Nitrogen Gln already separated its skeleton in decomposing fluid secreted traps. Most Gln-C...
Abstract Rice is the most important staple food for half of world's population, but also accounts about 10% all anthropogenic CH 4 emissions. In spite a wealth information on mechanistic basis and importance rice plant in mediating these emissions, significance root exudation emissions processes that determine are not well understood. Root exudates derive from photosynthate allocated to subjected anabolic catabolic processes. Key roots extent and, hence, emission agriculture, include (i)...
Aleppo pine (Pinus halepensis) is widely distributed in the Mediterranean region and other areas of world, where it has been introduced due to its adaptive capacity xerothermic conditions. The giant scale Marchalina hellenica often infests pine, as well pines, several southeastern European countries, causing declines. When combined with expected intensified heat drought events eastern Mediterranean, impact this biotic parameter on host pines may be exacerbated. importance understanding...
Abstract Background and Aims The processes connected with prey capture the early consumption of by carnivorous Dionaea muscipula require high amounts energy. aim present study was to identify involved in flytrap energy provision ATP homeostasis under these conditions. Methods We determined photosynthetic CO2 uptake chlorophyll fluorescence as well dynamics contents snap traps upon closure without prey. Key Results results indicate that capture, a transient switch from linear cyclic electron...
Very limited information is available on the drought tolerance of European beech and silver fir in mixed cultivation, both for mature forests natural regeneration. Particularly, little regarding significance memory effects exposure. Therefore, was analyzed seedlings these species grown cultivation present study. The results showed that previous-year hardening mediated enhanced biomass accumulation leaves root subsequent year, but did not impact growth. Total carbon (C) content decreased by...
