Summary: The study revealed that the expression variation of MdNRT2.4 in apple rootstocks contributes to differences in nitrate uptake capacity. Overexpression of MdNRT2.4 enhanced nitrogen absorption in apple seedlings under low nitrogen conditions by increasing net NO3- influx at the root surface. Additionally, MdNRT2.4-overexpressing apple seedlings recruited a greater number of bacterial taxa with nitrogen metabolic functions in the rhizosphere microbiota, especially Rhizobiaceae, highlighting the interaction between host plant genes and rhizosphere microbiota for nutrient uptake.

Summary: The bZIP transcription factor plays a critical role in the cold stress response in chrysanthemum. Overexpression of DgbZIP3 and DgbZIP2 enhances tolerance and activates the expression of DgPOD, an important gene related to peroxidase activity. The interaction between DgbZIP3 and DgbZIP2 regulates the expression of DgPOD and improves the defense mechanism against low-temperature stress.

Summary: The study found that ammonium nutrition impacts plant primary metabolism, cell wall remodelling, and redox homeostasis. Additionally, it induces proteins related to methionine metabolism and phytosiderophore synthesis. While increasing root iron content, plants fed with ammonium show higher sensitivity to iron deficiency.

Summary: In this study, loss-of-function mutation in SLAH3 gene in Arabidopsis thaliana enhanced tolerance to high KNO3 concentrations but reduced sensitivity to high K+. SLAH3 interacted with potassium channels GORK and SKOR to modulate membrane potential and coordinate the balance between nitrogen and potassium.

Summary: The research found that under salinity treatment, the expression of nitrate transporter 2.1 (SsNRT2.1) in Suaeda salsa was up-regulated, leading to increased nitrate uptake and accumulation. The inhibitor of plasma membrane H+-ATPase, Na3VO4, was found to affect this process.

Summary: This study reveals that the floral repressors, SVP and TPL, interact to inhibit flowering in chrysanthemum and Arabidopsis via a thermosensory pathway. These findings suggest a conserved mechanism of temperature-dependent flowering regulation in different species. This research is important for understanding the molecular basis of flowering regulation in plants.

Summary: In this study, 101 RWP-RKs were identified in Chrysanthemum lavandulifolium, including 38 NIN-like proteins (NLPs) and 31 RWP-RK domain proteins (RKDs), as well as 32 specific expansion members. qRT-PCR results showed that certain ClNLPs were up-regulated at the floral transition stage and negatively regulated by low nitrate conditions. Under optimal nitrate conditions, the flowering time was advanced, and the expression level of certain floral integration genes and ClCRYs was up-regulated.

Summary: This study revealed that MdBT2 undergoes posttranslational modifications in response to nitrate deficiency, and interacts with MdGRF11, a 14-3-3 protein, which negatively regulates the stability of MdBT2 protein via a 26S proteasome-dependent pathway. This leads to increased abundance of MdMYB1 proteins and activation of anthocyanin biosynthesis-related genes. The results demonstrate the critical role of 14-3-3 proteins in the regulation of nitrate deficiency-induced anthocyanin accumulation.

Summary: The uptake of ascorbic acid in neurons is mediated by the sodium-dependent vitamin C transporter-2 (SVCT2) and regulated by the synaptogenic adhesion protein, calsyntenin-3 (CLSTN3). Decreased expression levels of SVCT2 and CLSTN3 have been observed in the hippocampus of Alzheimer's disease mouse models and patients, indicating a potential pathophysiological significance in neuronal cells.

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: This study investigates the effects of different forms of nitrogen fertilizer on the reduction and dissolution of arsenic-bearing iron minerals and microbial-mediated arsenic transformation processes. The results show that nitrate nitrogen fertilizer reduces the bio-availability of arsenic in soil, while ammonium nitrogen fertilizer promotes the release of arsenic into porewater. However, the combined application of nitrate and ammonium nitrogen has no significant effect on arsenic concentration in rice grain and its transformation in paddy soils. These findings provide insights into the rational use of nitrogen fertilizers to reduce the risk of arsenic contamination in rice.

Summary: Rootstocks play a crucial role in vine cultivation by modulating nitrogen uptake and transport, which can impact the growth and development of grafted plants. Variations in rootstock responses to nitrogen absorption and utilization can lead to significant differences in biomass allocation between roots and shoots.

Summary: GLK1 is a key transcriptional regulator of photomorphogenesis, and, together with TCP15, it regulates the light-induced cotyledon opening and expression of related genes in plants. TCP15 forms a complex with GLK1 to coordinate the expression of cell expansion genes and genes involved in the development of the photosynthetic apparatus.

Summary: The study suggests that under high nitrate concentration conditions, high densities of rotifers enhance the nitrogen uptake capacity of phototrophic biofilms. Additionally, densities of rotifers and bacteria in biofilms are positively correlated under N - NO3- enriched conditions, indicating interaction between these two communities during the experimental period.
