Summary: Nitrogen availability and form significantly impact N uptake and assimilation in plants, with barley showing better growth under inorganic nitrogen (NO3-). Wild barley, particularly XZ179, appears to have a higher tolerance to organic nitrogen (glycine) compared to cultivated barley. Ammonium adversely affects growth parameters in both wild and cultivated barley genotypes.

Summary: This study found that nitrogen is an important factor for grain yield, grain nitrogen content, and grain protein content in rice. Certain rice genotypes showed higher nitrogen remobilization efficiency and nitrogen use efficiency under N deficiency and N sufficiency conditions, respectively. Identifying these genotypes is crucial for improving nitrogen fertilizer recovery rate and site-specific nitrogen management.

Summary: Cotton production efficiency in arid climates is constrained by low nitrogen utilization rate and high nitrogen application rate. Allocating more nitrogen to late application can alleviate these issues and improve plant growth and yield. A three-year field experiment showed that late nitrogen application narrowed plant width, increased canopy light transmittance, extended boll growth period, improved defoliation, and increased seed cotton yield. Therefore, adopting a late nitrogen application strategy can be an efficient fertilizer management approach in arid areas.

Summary: This study investigated the impact of water availability and nitrogen fertilization on plant growth, nutrient dynamics, and soybean crop yield. The results showed that water deficiency and absence of nitrogen fertilization decreased the accumulation and partitioning of various nutrients in plants. Although nitrogen fertilization led to increased nitrogen accumulation in tissues, it did not enhance yield significantly, while the highest seed yields were observed in plants under full irrigation regardless of nitrogen supplementation. However, deficient irrigation reduced the seed oil content in nitrogen-fertilized plants. In conclusion, nitrogen fertilization is crucial for nutrient homeostasis, and water availability affects biomass and nutrient accumulation, thus limiting soybean yield performance.

Summary: With increasing global warming, studying physiological responses to long-term heat stress is crucial for sustainable yield production. In this study, the effects of long-term heat stress on three cherry tomato accessions were evaluated. The results showed that HR17 had the highest fruit yield on the 35th day after heat treatment, while HR24 had the highest fruit yields with the smallest yield loss after longer heat treatment. Yield loss was associated with reductions in nitrogen use efficiency and water content under heat stress.

Summary: This study combined key genes involved in different nodes of nitrogen pathways to improve nitrogen uptake and assimilation in rice, leading to increased grain yield and nitrogen use efficiency. Overexpression of OsAMT1;2, OsGS1;2, and OsAS1 significantly increased plant biomass and grain yield, as well as glutamine synthase activity, free amino acids, and nitrogen utilization efficiency. Combining overexpression of OsAMT1;2, OsGS1;2, and OsAS1 is a promising breeding strategy for systematically increasing rice grain yield and nitrogen use efficiency.

Summary: Increasing soil nitrogen enhances calcium stress by promoting calcium leaching and affects the sensitivity of plants to calcium stress. However, the influence of increasing nitrogen on the soil calcium demand of seedlings is not well understood. This study investigated the effect of different concentrations of exogenous calcium on the growth, photosynthesis, calcium absorption, and water use efficiency of mulberry seedlings under different nitrogen levels. The results showed that there was an optimal concentration of soil calcium for mulberry seedling growth and photosynthetic rate, and nitrogen fertilizer application increased the optimal calcium concentration. Additionally, the water use efficiency of mulberry was positively correlated with soil calcium levels, except under the highest calcium treatment.

Summary: Leaf nitrogen content (LNC) is an important indicator for plant function, and in this study, sun-induced chlorophyll fluorescence (SIF) was proposed as a novel technique to estimate LNC. The results showed that SIF indices, particularly SIFR and SIFN, were better than traditional vegetation indices (VIs) in monitoring LNC and retrieving photosynthesis nitrogen use efficiency (PNUE). This study provides a new perspective for understanding plant nitrogen status and managing agriculture using remote sensing techniques.

Summary: Recent research suggests that modifying leaf-colour traits can improve canopy photosynthesis by allowing light penetration. However, the effects of leaf-colour modification on other growth-related traits and the mechanisms behind the increased photosynthesis remain unclear. This study found that yellow-leaf variants had a greater impact on crop growth and development compared to stay-green variants, but the delayed senescence in yellow-leaf variants contributed to improved photosynthesis.

Summary: The application of nitrogen fertilizer within a normal range can increase the leaf nitrogen content and photosynthetic rate of canola plants. This study analyzed two genotypes of canola with different leaf nitrogen content to determine the impact of nitrogen supply on leaf photosynthesis, mesophyll conductance, and nitrogen partitioning. The results showed that increasing nitrogen supply can enhance CO2 assimilation rate, mesophyll conductance, and photosynthetic nitrogen content in both genotypes.

Summary: Plants employ various adaptive strategies to respond to daylength variation, including adjustments in growth, photosynthesis, carbon utilization, and metabolic flux. Under short-day conditions, plants compensate for reduced CO2 fixation by enhancing photosynthetic rates and reducing respiration in the light, while also reducing the partitioning of glucose and increasing starch accumulation to sustain carbon availability during the longer night. Isotopic labeling results demonstrate substantial changes in the partitioning of amino acids and TCA cycle intermediates between rapidly and slowly turning over pools in response to different daylengths.

Summary: Improving nitrogen use efficiency in crops can help reduce nutrient loss in soil and alleviate environmental pressure. Different application rates of nitrogen fertilizer have varying effects on biomass accumulation, nitrogen accumulation, and nitrogen use efficiency in flue-cured tobacco plants. The Hongda cultivar exhibits higher biomass and nitrogen accumulation, as well as better nitrogen use efficiency, compared to the K326 cultivar. This is attributed to the Hongda cultivar's ability to accumulate more carboxylation, respiratory, and photosynthetic system nitrogen.

Summary: This study assessed the impact of N supply on leaf anatomical, biochemical, and photosynthetic features in tobacco, revealing that high N treatment led to enhanced photosynthesis due to increased CO2 diffusion conductance and photosynthetic biochemical capacity. The increase in gm in leaves treated with high N was related to changes in leaf anatomy, but the rapid response to N top-dressing could not be fully explained by leaf anatomical modifications.

Summary: This study aimed to uncover the physiological basis of differential tuber-Zn concentration between potato cultivars and identify the major source(s) of Zn to the tubers. The results showed that different cultivars have varied Zn concentration, Zn content, and biomass partitioning, with Lady Rosetta translocating higher amounts of Zn to the tubers while Cara accumulates relatively more Zn in the stems.
