A novel biosensor to monitor proline in pea root exudates and nodules under osmotic stress and recovery [0.03%]
一种新型生物传感器监测渗透胁迫及恢复过程中豌豆根系分泌物和根瘤中的脯氨酸动态分布
María I Rubia,Vinoy K Ramachandran,Cesar Arrese-Igor et al.
María I Rubia et al.
Background and aims: Plant and bacteria are able to synthesise proline, which acts as a compound to counteract the negative effects of osmotic stresses. Most methodologies rely on the extraction of compounds using destruc...
Regulation of nitrogen fixation from free-living organisms in soil and leaf litter of two tropical forests of the Guiana shield [0.03%]
圭亚那盾牌两片热带森林土壤和枯落层中游离有机体固氮作用的调控
Leandro Van Langenhove,Thomas Depaepe,Sara Vicca et al.
Leandro Van Langenhove et al.
Background and aims: Biological fixation of atmospheric nitrogen (N2) is the main pathway for introducing N into unmanaged ecosystems. While recent estimates suggest that free-living N fixation (FLNF) accounts for the maj...
Chloride and sulfate salinity differently affect biomass, mineral nutrient composition and expression of sulfate transport and assimilation genes in Brassica rapa [0.03%]
氯离子和硫酸盐对蔊菜生物量、矿质营养成分及硫酸根转运和同化基因表达的影响不同
Martin Reich,Tahereh Aghajanzadeh,Juliane Helm et al.
Martin Reich et al.
Background and aims: It remains uncertain whether a higher toxicity of either NaCl or Na2SO4 in plants is due to an altered toxicity of sodium or a different toxicity of the anions. The aim of this study was to determine ...

Edward J M Joy et al.
Background and aims: Use of zinc (Zn) fertilisers may be cost-effective in increasing crop yields and in alleviating dietary Zn deficiency. However, Zn fertilisers are underutilised in many countries despite the widesprea...
Significance of root hairs at the field scale - modelling root water and phosphorus uptake under different field conditions [0.03%]
根毛在田间尺度上的意义-不同条件下根系吸水和磷营养的模拟研究
S Ruiz,N Koebernick,S Duncan et al.
S Ruiz et al.
Background and aims: Root hairs play a significant role in phosphorus (P) extraction at the pore scale. However, their importance at the field scale remains poorly understood. ...
Soil resilience and recovery: rapid community responses to management changes [0.03%]
土壤的恢复力及修复：管理变化下的群落快速响应
Penny R Hirsch,Deveraj Jhurreea,Jennifer K Williams et al.
Penny R Hirsch et al.
Background and aims: Soil degradation is a major global problem; to investigate the potential for recovery of soil biota and associated key functions, soils were monitored during the early years of conversion between perm...
Methods to estimate changes in soil water for phenotyping root activity in the field [0.03%]
估算田间表征根系活力的土壤水分变化方法
W R Whalley,A Binley,C W Watts et al.
W R Whalley et al.
Background and aims: There is an urgent need to develop new high throughput approaches to phenotype roots in the field. Excavating roots to make direct measurements is labour intensive. An alternative to excavation is to ...
Chemical changes in organic matter after fungal colonization in a nitrogen fertilized and unfertilized Norway spruce forest [0.03%]
氮肥施用和不施用情况下云杉林木的真菌定植对有机物质化学变化的影响
César Nicolás,Juan P Almeida,Magnus Ellström et al.
César Nicolás et al.
Background and aims: Decomposition and transformation of organic matter (OM) in forest soils are conducted by the concomitant action of saprotrophic and mycorrhizal fungi. Here, we examine chemical changes in OM after fun...
Impacts of peat bulk density, ash deposition and rainwater chemistry on establishment of peatland mosses [0.03%]
泥炭容重、灰分沉降和雨水化学性质对泥炭地藓类植物建群的影响
Alice Noble,Sheila M Palmer,David J Glaves et al.
Alice Noble et al.
Background and aims: Peatland moss communities play an important role in ecosystem function. Drivers such as fire and atmospheric pollution have the capacity to influence mosses via multiple pathways. Here, we investigate...
Plant exudates improve the mechanical conditions for root penetration through compacted soils [0.03%]
植物分泌物通过改善紧实土壤的力学状况来促进根系生长穿透
E Oleghe,M Naveed,E M Baggs et al.
