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...

Nitrogen is an essential element for plant growth and yield. Improving Nitrogen Use Efficiency (NUE) of crops could potentially reduce the application of chemical fertilizer and alleviate environmental damage. To identify new NUE genes is therefore an important task in molecular breeding. Macroautophagy (autophagy) is an intracellular process in which damaged or obsolete cytoplasmic components ...

Increasing yield potential of lowland rice remains to be the top priority in rice geneticimprovement programmes, because rice farmers’ primary concern is still grain yield and world rice production has to increase by 1% annually in the next 20 years to meet the demand of the growing population. Improvements in yield potential of irrigated lowland rice were achieved under ample supply of water a...

Nitrogen (N) is the primary growth-limiting nutrient in many terrestrial ecosystems, and therefore plant production per unit N taken up (i.e., N use efficiency, NUE) is a fundamentally important component of ecosystem function. Nitrogen use efficiency comprises two components: N productivity (A(N), plant production per peak biomass N content) and the mean residence time of N in plant biomass (M...

Excretion of excess dietary N from dairy cows contributes to environmental pollution, with ammonia, nitrate, and nitrous oxide being the major pollutants. Apparent efficiency of feed N use for milk protein production is typically about 25%, depending on diet. However, there are long periods when a dairy cow is not productive (during heifer growth and when dry) which reduce lifetime apparent N u...

enhancing nitrogen use efficiency is one of the most important strategies for improving productivity in agriculture and reducing risk of environmental pollutions in sustainable agriculture. in order to study the effects of different levels of organic manure and chemical fertilizer on nitrogen uptake efficiency (nupe), nitrogen utilization efficiency (nute) and nitrogen use efficiency (nue) of i...

Assembly of active Fe-hydrogenase in the chloroplasts of the green alga Chlamydomonas reinhardtii requires auxiliary maturases, the S-adenosylmethionine-dependent enzymes HydG and HydE and the GTPase HydF. Genes encoding homologous maturases had been found in the genomes of all eubacteria that contain Fe-hydrogenase genes but not yet in any other eukaryote. By means of proteomic analysis, we id...

The overuse of nitrogen fertilizers in agricultural production China, resulting negative impacts on the environment, has become a serious issue. Thus, reducing use one top priorities for achieving sustainable development goals Chinese sector. Searching effective approaches to reduce is essential and environmental sustainability. In this study, we selected Yangtze River Basin as research area, o...
