Phosphorus (P) is a major plant nutrient. It transported into and allocated inside plants by four families of phosphate transporters (PHT1 to PHT4) with high or low affinity phosphate. Here, we studied whole-plant P uptake kinetics expression profiles members the PHT under high, intermediate availability in woody crop poplar (Populus × canescens) relation performance.Poplars exhibited strong growth reduction increased use efficiency response lower availabilities. The relative rate decreased...
Roots facilitate acquisition of macro- and micronutrients, which are crucial for plant productivity anchorage in the soil. Phosphorus (P) is rapidly immobilized soil hardly available plants. Adaptation to P scarcity relies on changes root morphology towards rooting systems well suited topsoil foraging. Root-system architecture (RSA) defines spatial organization network comprising primary, lateral stem-derived roots important adaptation stress conditions. RSA phenotyping a challenging task...
Potato is considered to have a low phosphorus (P) efficiency compared other crops. Therefore, P fertilization requirements are high. New cultivars with improved may contribute save limited mineral sources and reduce eutrophication of surface water bodies. The present study aims characterize the different potato genotypes identify mechanisms that improve in cultivated potato. A diversity set 32 accessions was used assess their efficiency. From this set, five were selected two pot experiments...
Phosphorus (P) is an essential macronutrient required for plant metabolism and growth. Its acquisition by plants depends on the availability of dissolved P in rhizosphere characteristics uptake mechanisms such as root-system architecture (RSA). Compared to other crops, potato (Solanum tuberosum L.) has a relatively poor efficiency. This mainly due its shallow sparsely branched root system, resulting rather limited exploitable soil volume. Information about genotypes with RSA traits suitable...
Abstract Background Seed retention is the basic prerequisite for seed harvest. However, only little breeding progress has been achieved this trait in major forage grasses. The aim of study was to evaluate potential plant genetic resources important fodder grasses Festuca pratensis Huds. and Lolium perenne L. as source process. Furthermore, morphology abscission zone, where shattering occurs, studied on cell tissue level different developmental stages contrasting accessions. Results 150 286...
Phosphorus (P) is an essential plant nutrient, but its availability often limited in soil. Here, we studied changes the transcriptome and nutrient element concentrations leaves roots of poplars (Populus × canescens) response to P deficiency. starvation resulted decreased S major cations (K, Mg, Ca), increased N, Zn Al, while C, Fe Mn were only little affected. In >4,000 >9,000 genes differently expressed upon starvation. These clustered eleven co-expression modules which seven correlated...
Abstract Long-term field experiments (LTFEs) can provide an extensive overview on the effectiveness of phosphorus (P) management. In order to have a detailed insight into availability and distribution P in soil as affected by organic inorganic fertilizers (no P, triple-superphosphate (TSP), compost + TSP), samples collected at LTFE established 1998 Northern Germany different sampling dates depths were subjected characterization including double-lactate method (P-dl) standard test, degree...
Soil salinity is a critical problem for rice production and also often associated with phosphors (P) deficiency. Plant hormones, like brassinosteroids, were shown to play role in plant responses different stresses are expected mitigate salt stress. The aim of this study was compare shoot growth root architecture traits two cultivars (INCA LP-5 Perla de Cuba) during early development response salt, P limitation brassinosteroid. Seeds placed (I) paper rolls 7 days (II) mini-rhizotrons 21...
Abstract Background Plants are not able to take up organically bound phosphorus (P) before it is hydrolyzed by extracellular phosphatases while intracellular play a role in P remobilization. Aims The aim of this study was evaluate intra‐ and acid phosphatase activity as well root shoot growth two modern starch potato cultivars at different levels deprivation. Methods In vitro propagated plantlets (cultivars Kuba Cardoso) were grown sand fertigated with five concentrations, ranging from 1...
In a future exposed to threats of climate change, sustainable biomass production will be crucial. Maize (Zea mays) and sorghum (Sorghum sp.) are important crops for human animal nutrition, as well bioenergy. The aim this study was investigate maize in mixed cropping with soybean (Glycine max) faba bean (Vicia faba) regarding yield, drought tolerance, phosphorus (P) availability, enzyme activity soil affected by the single combined effects water P supply two outdoor pot trials rainout...
