In addition to light and water, CO 2 and mineral elements are required for plant growth and
development. Among these factors, nitrogen is critical, since it is needed to synthesize …

In the majority of agricultural growing regions, crop production is highly dependent on the
supply of exogenous nitrogen (N) fertilizers. Traditionally, this dependency and the use of N …

Dissimilatory nitrate reduction to ammonium (DNRA), the nearly forgotten process in the
terrestrial nitrogen (N) cycle, can conserve N by converting the mobile nitrate into non …

Publisher Summary This chapter discusses the physiological causes and ecological
consequences of inherent variation in growth rate among higher plants. When grown under …

Plant respiration is a large, environmentally sensitive component of the ecosystem carbon
balance, and net ecosystem carbon flux will change as the balance between photosynthesis …

This revision maintains the position of Forest Ecosystems as the one source for the latest
information on the advanced methods that have enhanced our understating of forest …

Long-distance transport of nitrate requires xylem loading and unloading, a successive
process that determines nitrate distribution and subsequent assimilation efficiency. Here, we …

Little is known about the molecular and regulatory mechanisms of long-distance nitrate
transport in higher plants. NRT1. 5 is one of the 53 Arabidopsis thaliana nitrate transporter …

We compared the effects of temperature on rates of microbial respiration, N mineralization,
nitrification, and P mineralization in soils from six arctic ecosystems located along a …
