2023年10月7日,Nature plants在线发表了南京农业大学李姗教授团队题为“Improving rice nitrogen-use efficiency by modulating a novel monouniquitination machinery for optimal root plasticity response to nitrogen”的研究论文。该团队在水稻中鉴定到一...
Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth’s atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammoni...
Plants need nutrients to grow. So scientists were surprised to learn that giant kelp maintains its impressive growth rates year-round, even in summer and early fall when ocean currents along the Calif...
The objectives of the experiment were to study nitrogen fractions of the Cornell Net Carbohydrate and Protein System (CNCPS) and digestibility of organic matter (OMD) and crude protein (CPD) along wit...
The objective of the current study was to evaluate the effect of supplementation of either L-methionine (L-Met) or DL-methionine (DL-Met) to diets of starter pigs on nitrogen (N) balance, metabolism, ...
The need to reduce anthropogenic nutrient inputs to aquatic ecosystems in order to protect drinking-water supplies and to reduce eutrophication, including the proliferation of harmful algal blooms...
In this study, nutritive values of rapeseed (R), rapeseed meal-expeller A (RM-A), rapeseed meal-expeller B (RM-B) and extracted rapeseed meal (ERM) were compared. The trials were performed using the i...
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients a...
This study evaluated the in situ ruminal degradability, and subsequent small intestinal digestibility (SID) of dry matter, crude protein (CP), and amino acids (AA) of cottonseed meal (CSM), sunflower ...
Nutrient pollution from nitrogen and phosphorus in streams has long been known to increase carbon production by algae, often causing nuisance and harmful algal blooms.But according to results of a new...
How effectively plants utilize nitrogen (N), the most limiting nutrient in natural ecosystems, will largely determine the success of plants in intra- and inter-specific competition. Theory suggests th...
Nitrogen deposition is changing biodiversity on Earth. We need to understand the underlying mechanisms to conserve biodiversity better. Both selection and chance are potential mechanisms, and they may...
Nitrogen (N) deposition is widely considered an environmental problem that leads to biodiversity loss and reduced ecosystem resilience; but, N fertilization has also been used as a management tool for...
We present research aimed at determining the role of soil structure in the organization of microbial communities in soil. We have focused on the microbial communities involved in functional roles with...
Sustainability is one of the biggest goals of humankind in the new millennium. An increasing global demand on agricultural products stimulates agricultural expansion in Brazil, especially in the South...
