Summary: It was found that there is substantial genetic variation in maize for multiple ion-uptake rates and specific nutrient uptake rates are positively correlated with specific root respiration, indicating shared mechanisms governing uptake. RNA-seq analysis of maize lines with high and low specific uptake rates identified key regulatory components involved in nutrient uptake. The high-throughput multiple ion-uptake kinetics pipeline will further understanding of nutrient uptake and help identify breeding targets for crops with more efficient nutrient acquisition.

Summary: Aerosols can contribute to plant nutrition via foliar uptake, especially at night when humidity is high. Although stomata tend to be closed at night, plants can benefit from nocturnal stomatal opening to increase humidity and facilitate nutrient uptake. This hypothesis was supported by experiments on P-deficient soil.

Summary: This study describes a high throughput phenotyping platform for testing the effects of small signaling peptides (SSP) on root uptake of multiple nutrients in plants. The results show that SSP CEP1 can enhance nitrate uptake rate in Medicago truncatula plants deprived of nitrogen. Furthermore, specific structural variants of CEP1 peptides not only enhance nitrate uptake, but also phosphate and sulfate uptake in both Medicago truncatula and Arabidopsis thaliana. Transcriptome analysis reveals that CEP1 peptides can induce the expression of several genes, including nutrient transporters and signaling pathway genes.

Summary: This study aimed to investigate the relationship between deep roots in winter wheat and drought tolerance, and how this relationship is affected by genotype and nitrogen fertilization. The study found that deep roots were correlated with higher grain yield, uptake of water and nitrogen from deeper layers, and tolerance to drought. Therefore, breeding efforts should consider enhancing deep rooting for more climate resilient crops.

Summary: Winters in snow-covered regions have warmed, affecting nutrient export and water quality. Rain-on-snow events, a major flood-generating mechanism, impact more than half of the contiguous United States, putting nitrogen and phosphorus pools at risk of export. The lack of sufficient data hampers accurate measurement and prediction of these large-scale wintertime nutrient export events.

Summary: This study investigated the effects of graphene oxide (GO) on the growth, structure, and physiology of alfalfa roots. The results showed that high levels of GO significantly reduced root length, diameter, volume, dry weight, number of lateral roots, and root activity, as well as vascular cylinder diameter, periderm thickness, vessel diameter, and phellem thickness. The presence of GO also inhibited the uptake of essential nutrients by the roots.

Summary: In this study, the deposition rates of atmospheric nutrients in a previously unexplored Siberian mountain region were reported, along with their potential effects on lake phytoplankton biomass limitation. Despite low atmospheric nitrogen deposition rates inducing nitrogen limitation in unproductive mountain lakes, phosphorus deposition was also found to be extremely low, resulting in unaffected N: P ratios in lake water. This suggests that the studied lakes' phytoplankton are split between phosphorus and nitrogen limitation even with very low nutrient deposition rates.

Summary: Juveniles and canopy trees may not exhibit similar nitrogen acquisition responses to soil temperature change caused by variation in snow cover over winter. The use of (15)N tracer can effectively track the effects of variation in soil frost on plant nitrogen acquisition. Estimating the nitrogen acquisition responses of mature canopy trees based on juveniles may lead to overestimation due to differences in (15)N enrichment responses.

Summary: Research on ruffed grouse in high-latitude environments shows that they seek refuge in thermally stable microhabitats under deep snow during winter to buffer against the negative effects of cold temperatures on physiological stress levels. Despite variability in snow depth, snow density, and temperature, areas with elevated stress levels were consistently identified across the landscape, highlighting the importance of stress-scapes in understanding the indirect effects of stressors.

Summary: A study conducted on drip-fertigated winter wheat on the Loess Plateau of China found that water and fertilizer management has significant effects on crop growth, yield, and grain quality. Adequate supply of water and nutrients promotes wheat growth and nutrient uptake, but excessive supply can also affect grain quality. Under sufficient water and fertilizer supply, the stem, leaf, and rachis + glume obtained higher proportions of nutrients, while the harvest index for grain nitrogen and phosphorus decreased. Increasing irrigation and fertilization levels can increase yield and irrigation water use efficiency, but careful control is needed to avoid excessive supply.

Summary: This study investigated the effect of exogenous histidine supply on the translocation of zinc (Zn) and nickel (Ni) in shoot-excised root systems of non-accumulating species. The results showed that pretreatment with histidine significantly increased the translocation and exudation of Zn and Ni. However, histidine pretreatment did not affect the translocation of Ni in Arabidopsis thaliana. Additionally, pretreatment with alanine did not increase the translocation of Zn and Ni.

Summary: Phytochelatins (PCs) are small peptides with cysteine-rich structures that can bind to metal(loid)s. They are mainly involved in detoxifying cadmium and arsenic (III) as well as other metal ions that have high affinities for SH-groups. This review provides a comprehensive account of the biosynthesis, structure, and role of PCs in metal(loid) transport and sequestration in plant cells. It also examines the role of PCs in hyperaccumulator and excluder plants and concludes that while PCs do not contribute to metal(loid) hyperaccumulation, they play a crucial role in metal(loid) homeostasis.

Summary: This pilot study aimed to compare the effects of zinc and nickel on the fatty acid profiles, oxidative stress and desaturase activity in two different species of Arabidopsis plants, one being a zinc hyperaccumulator and the other being a metal excluder. The results showed that significant changes in fatty acid composition were observed in both species, but the changes were metal-dependent and species-specific. These metal-induced changes in fatty acid composition could affect the fluidity and stability of membranes in the plants, potentially contributing to their metal tolerance or acclimation.

Summary: This study investigated the effects of high-intensity light on pigment content, photosynthetic rate, and fluorescence parameters of photosystem II in high-pigment tomato mutants (hp 3005) and low-pigment mutants (lp 3617). The results showed that the high-pigment mutant displayed increased levels of photosynthetic pigments and anthocyanins, while the low-pigment mutant showed heightened content of ultraviolet-absorbing pigments. The high-pigment mutant exhibited the highest photosynthetic rate, photosystem II activity, antioxidant capacity, and carotenoid content after 72 hours of exposure to intense light, suggesting superior physiological adaptability and reduced photoinhibition.
