Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts

Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plant species have demonstrated a better ability to tolerate and accumulate heavy metals than their co‐occurring native plants. Given the potential biological toxicity of heavy metals to phytopathogens, we postulated that heavy metal contamination could ...

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession
Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

Ecological relationship between biofuel-producing crops, microalgae and the corresponding microorganisms [PDF]
随着近年来传统化石燃料消耗所引发的能源短缺危机及全球气候变暖等环境问题的不断加剧,世界各国都在关注并积极开展有关可再生清洁能源的开发与利用研究。其中,在边际土地种植柳枝稷、芒草、杨树及柳树等多年生纤维素类非粮食作物(第二代生物能源物质)和水体中培养产油微藻(第三代生物能源物质),作为生物乙醇及生物柴油的原材料,由于能避免“与人争粮”及“与粮争地”的矛盾,而引起广泛关注。本研究第一部分通过研究美国能源部“五大湖生物能源研究中心”(GLBRC)边际土地上能源作物与土壤微生物的相互关系 ...
