Leaf senescence and nitrogen remobilization efficiency in oilseed rape (Brassica napus L.).
Despite its worldwide economic importance for food (oil, meal) and non-food (green energy and chemistry) uses, oilseed rape has a low nitrogen (N) use efficiency (NUE), mainly due to the low N remobilization efficiency (NRE) observed during the vegetative phase when sequential leaf senescence occurs. Assuming that improvement of NRE is the main lever for NUE optimization, unravelling the cellul...
متن کاملNitrogen recycling and remobilization are differentially controlled by leaf senescence and development stage in Arabidopsis under low nitrogen nutrition.
Five recombinant inbred lines (RILs) of Arabidopsis (Arabidopsis thaliana), previously selected from the Bay-0 x Shahdara RIL population on the basis of differential leaf senescence phenotypes (from early senescing to late senescing) when cultivated under nitrogen (N)-limiting conditions, were analyzed to monitor metabolic markers related to N assimilation and N remobilization pathways. In each...
متن کاملGenetic analysis of the function of major leaf proteases in barley (Hordeum vulgare L.) nitrogen remobilization.
Most of the nitrogen harvested with the seeds of annual crops is remobilized and retranslocated within the plant between anthesis and plant death. While chloroplasts contain most of the reduced nitrogen present in photosynthetically active leaf cells, the (major) pathway(s) involved in the degradation of their proteins prior to the retranslocation of the resulting amino acids are unknown. In th...
متن کاملModeling Nitrogen Species as Pollutants: Thermochemical Influences.
To simulate emissions of nitrogen-containing compounds in practical combustion environments, it is necessary to have accurate values for their thermochemical parameters, as well as accurate kinetic values to describe the rates of their formation and decomposition. Significant disparity is observed in the literature for the former, and we therefore present herein high-accuracy ab initio gas-phas...
متن کاملNitrogen metabolism and remobilization during senescence.
Senescence is a highly organized and well-regulated process. As much as 75% of total cellular nitrogen may be located in mesophyll chloroplasts of C(3)-plants. Proteolysis of chloroplast proteins begins in an early phase of senescence and the liberated amino acids can be exported to growing parts of the plant (e.g. maturing fruits). Rubisco and other stromal enzymes can be degraded in isolated ...
