Summary: This study demonstrates that the accumulation of carotenoids in carrot cells is affected by nitrogen concentration and the ratio of nitrate to ammonium, while other components in the media do not significantly impact carotenoid content or callus growth.

Summary: Plants uptake and assimilate nitrogen from the soil, and nitrate and ammonium transporters play important roles in this process. Nitrogen is then incorporated into organic compounds through nitrogen metabolism pathways. Nitric oxide has been found to enhance plant survival under drought stress, and the interaction between nitrogen and salt stress has been studied. Excessive use of nitrate fertilizers can have negative impacts on health and the environment, highlighting the importance of alternative strategies. Genomics can identify new genes related to nitrogen fixation, which can be utilized to improve plant productivity.

Summary: Molecular hydrogen, nitrate reductase, and nitric oxide can synergistically regulate nitrate assimilation and seed size in response to nitrogen starvation conditions. Genetic and molecular evidence suggests that nitrate reductase may be a target of hydrogen sensing, positively regulating nitrogen use efficiency and seed size in Arabidopsis. These findings provide insights into the signaling and functions of hydrogen in plant metabolism.

Summary: The study found that at low boron supply, plants fed with nitrate and ammonium had similar B-10 uptake rates, accumulation, and xylem B-10 concentrations, but these attributes were reduced at high boron supply. Ammonium-induced acidity and nitrate-induced alkalinization led to altered B distribution between roots and shoots as well as different B transport mechanisms in plants.

Summary: The study focused on the molecular mechanisms of nitrogen acquisition and assimilation processes in the fungus Verticillium dahliae. It demonstrated that nitrate metabolism requires additional energy input, while ammonium metabolism is accompanied by reductions in specific cellular processes. The findings shed light on the convergent and distinctive regulatory mechanisms between preferred and alternative nitrogen metabolism in V. dahliae at the transcriptome level.

Summary: Nitrogen is an essential element for plant growth, and different nitrogen sources and forms have significant effects on the biomass, quality, and metabolite composition of lettuce. The NH4+/NO3- ratio plays a crucial role in determining the chlorophyll content and biomass of lettuce. The 25% NH4+/75% NO3- ratio is the most suitable for increasing lettuce biomass in hydroponic cultivation systems. Different concentrations of nitrogen sources also affect the taste and quality-related compounds in lettuce.

Summary: Nitrogen uptake and assimilation are crucial for plant growth and productivity. This study evaluated eleven rice genotypes under sufficient and low nitrogen conditions, and identified a genotype associated with enhanced nitrogen levels and assimilation. The findings provide important insights for breeding nitrogen use-efficient rice varieties.

Summary: Nitrogen is essential for crop yields, but excessive application can lead to increased production costs and environmental problems. Understanding the molecular mechanisms of nitrogen use efficiency (NUE) and breeding crops with higher NUE is crucial. NUE is determined by nitrogen uptake, transport, assimilation, and remobilization, involving key enzymes like NR, NiR, GS, and GOGAT.

Summary: This study found that tire wear particle-derived compounds can be absorbed by lettuce and transformed into more stable compounds in the plant. Furthermore, continuous tire wear leads to a resupply and replenishment of these compounds in the lettuce leaves. This is an important aspect for the impact assessment of tire wear in the environment.

Summary: This study investigated the effect of nitrate-dependent suberization in maize roots on the uptake and accumulation of cadmium (Cd). The suberization in maize roots was significantly lower under high nitrate supply compared to low nitrate. The decrease in suberin content was mainly due to a decrease in aliphatic suberin, while there was no difference in aromatic suberin content between different nitrogen treatments.

Summary: Nitrogen strongly affects plant growth and metabolism. This study investigated the effects of different concentrations of NH4+ on the growth of Arnebia euchroma hairy roots (AEHR) and the accumulation of shikonin in them. The results showed that low concentrations of NH4+ promoted growth and shikonin synthesis, while high concentrations inhibited growth and shikonin accumulation in AEHR.

Summary: The study investigated the pattern of arsenic uptake and its influence on plant growth in bean and lettuce at different developmental stages. The human health risk from consuming these arsenic-laced vegetables was also determined. The results showed that arsenic had an impact on the biomass of plant parts, but the changes were not significant. The concentration of arsenic in the plants increased with the increase in arsenic concentration in the irrigation water. Lettuce had higher transfer factor at the young stage, while bean had the highest transfer factor at the flowering stage. The concentration of arsenic in lettuce was significantly higher than that in bean, posing significant health risks.
