Summary: This study investigated the changes in nitrogen metabolism in phosphorus-starved bloom-forming cyanobacteria. The results showed that decreased expression of nitrogen source transporters led to reduced nitrogen uptake and nitrogen deficiency. Additionally, phosphorus starvation resulted in a drastic decrease in phycocyanin content. While external nitrogen supply did not significantly alter the transcription of nitrogen metabolism-related genes, it still helped to maintain the survival of phosphorus-starved cells.

Summary: This study investigated the effect of elevated CO2 on phosphorus (P) requirement for enhanced N2 fixation in white lupin plants. The results showed that elevated CO2 increased the critical P concentration needed for N2 fixation, indicating that more P is required to support greater N2 fixation under elevated CO2. Additionally, elevated CO2 improved N2 fixation in P-deficient plants by increasing nitrogenase activity and excess cation uptake.

Summary: Through a greenhouse trial, we found that non-native pioneer plant Lupinus angustifolius can improve the conditions of mine tailings by increasing nitrogen and promoting phosphorus transformation, thereby facilitating the growth of subsequent native plants. Significant increases in soil organic phosphorus and organo-bound aluminum minerals suggest the initiation of pedogenesis in mine tailings.

Summary: Nutrition is a crucial factor in the growth and development of plants, particularly in terms of flowering. The process of flowering represents a transition from vegetative to reproductive stages, which requires nutrient consumption. Furthermore, nutrients such as nitrate act as signals that impact flowering. This review aims to enhance our understanding of how plant nutrition influences flowering by examining the relationships between nutrients (primarily nitrogen, phosphorus, and potassium) and the flowering process.

Summary: Substrate-grown crops in southern Spain make up 10% of intensive greenhouse horticulture, and their free-draining nature leads to significant nutrient loss in drainage, causing water contamination. This study examined two management approaches, ratio-based and uptake concentration-based, to reduce nutrient loss in drainage. Both strategies significantly reduced nutrient application, with ratio-based management reducing nutrient loss by 58-77% and uptake concentration-based management reducing it by 65-80%.

Summary: The study finds significant variation in the methods used by European countries to set river nutrient thresholds, with some countries relying on expert judgement or statistical distribution, while others prefer statistical relationships based on biological variables. For the first time, an ecology-based approach is used to derive nutrient thresholds for various river types in Central Europe. The results demonstrate that adopting ecology-based nutrient targets could improve sustainable river management where nutrients are the main pressure preventing the achievement of good ecological status.

Summary: In understanding the drought tolerance of canola, it is important to consider the efficiency of the antioxidant response and the potential involvement of calcium-dependent protein kinases (CDPKs). This study found that higher activities of antioxidant enzymes were observed in drought-tolerant canola cultivars, suggesting the importance of antioxidant response in drought tolerance. Additionally, the expression of BnaCDPK genes and the presence of stress-related elements in their promoter regions implied that CDPKs may play a role in regulating canola's response to drought stress.

Summary: The maintenance of intracellular nitrogen-fixing bacteria has detrimental effects on proteins' location and gene expression, leading to decreased fitness of the host cell. The high vulnerability of nodules to salt stress may be a result of altered mechanisms involved in excluding Na+ from the host cytoplasm. The misplacement of Na+/K+ exchangers in infected cells suggests a loss of functionality, and downregulation of ion transporters and Na+/K+ exchangers genes in mature nodules further weakens the ability to exclude Na+. Salt-treated nodules show higher accumulation of Na+ in infected cells compared to non-infected cells. These findings indicate that the inability of infected cells to withstand salt stress is due to defects in protein localization and reduced expression of key genes involved in ion homeostasis, leading to premature senescence and termination of symbiosis.

Summary: Lupin is a versatile legume crop that can grow in various environmental conditions where other crops struggle. It has unique seed nutrients and can be used for phytoremediation. The bacteria that nodulate Lupins belong to different genera, including Bradyrhizobium and other fast-growing genera. Horizontal gene transfer plays a crucial role in facilitating the symbiotic relationship between Lupin and these bacteria. Further studies on unstudied Lupinus species and their microsymbionts will enhance our understanding of Lupin's adaptability and its potential for marginal soils.
