Ammonium (NH4+) toxicity is an issue of global ecological and economic importance. In this
review, we discuss the major themes of NH4+ toxicity, including the occurrence of NH4+ in …

Many forest ecosystems have evolved at sites with growth‐limiting nitrogen (N) availability,
low N input from external sources and high ecosystem internal cycling of N. By contrast …

Abstract Using a new Arabidopsis (Arabidopsis thaliana) mutant (Atnrt2. 1-nrt2. 2) we
confirm that concomitant disruption of NRT2. 1 and NRT2. 2 reduces inducible high-affinity …

Ammonium and nitrate are the prevalent nitrogen sources for growth and development of
higher plants. Here, we report on the characterization of the ammonium transporter (AMT) …

Amino acids constitute a potentially important source of nitrogen for plants in boreal forest
ecosystems. Accordingly, it may be suggested that distinct plant species differing abilities to …

A wide range of recent studies have indicated that organic nitrogen may be of great
importance to plant nitrogen (N) nutrition. Most of these studies have, however, been …

Soil is a complex system where biotic (eg, plant roots, micro-organisms) and abiotic (eg,
mineral surfaces) consumers compete for resources necessary for life (eg, nitrogen …

喀斯特地质与生态系统是地球表层系统中的重要组成部分, 其变化将对其他地区以及整个地球
系统产生影响. 生物地球化学循环是全球和区域变化研究的核心内容, 而生态系统的演化与系统 …

Several recent studies have suggested that control of isoprene emission rate is in part
exerted by supply of extrachloroplastic phosphoenolpyruvate to the chloroplast. To test this …

Soil salinity is a major abiotic stressor affecting plant growth. Salinity affects nitrification and
ammonification in the soil, however, limited information is available on the influence of …
