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: This study identified and characterized mutation sites responsible for two types of nodulation-deficient phenotypes in chickpea using sequencing technologies. The results showed that one mutation was caused by the deletion of the entire nodulation gene, while the other mutation was caused by a small base deletion. The study also found that previous work was hindered by genomic misassemblies.

Summary: Nitrogen is essential for plant growth and productivity, and legumes forming a symbiotic relationship with nitrogen-fixing rhizobia bacteria allows them to thrive in nitrogen-poor environments. However, hosting nitrogen-fixing bacteria comes with metabolic costs and requires regulation. The symbiosis is regulated through three signal transduction pathways, controlling the communication and organ formation of symbiotic signals.

Summary: The specific mechanisms by which nitrogen affects nodulation and nitrogen fixation in leguminous crops are still unclear. This study investigates the effects of exogenous nitrogen on proteins and metabolites in soybean root nodules. The findings reveal that exogenous nitrogen regulates multiple metabolic pathways, promotes the synthesis of signaling molecules, and inhibits energy supply for nitrogen fixation, leading to reduced root nodule growth and nitrogen fixation.

Summary: The plant hormone gibberellin plays a crucial role in the development of legume nodules. Several GA biosynthesis and catabolism enzyme encoding genes are essential for nodule formation in soybean. Manipulating the level of GA by disrupting GA oxidase genes or treating with exogenous GA can affect the expression of nodulation genes and alter infection thread and nodule phenotypes.

Summary: Nitrogen availability and uptake levels can influence nutrient accumulation in plants. This study investigated the effects of valine and urea supplementation on the growth, lignin content, and carbon and nitrogen metabolism of 'Ruiguang 39/peach' trees. Valine application inhibited shoot longitudinal growth and increased lignification, while also increasing the levels of protein enzymes involved in sucrose and nitrogen metabolism. Urea application increased protein levels of carbon- and nitrogen-metabolizing enzymes, but reduced overall nutrient accumulation and lignin content per unit tree mass. In conclusion, valine application positively affects carbon and nitrogen nutrient accumulation in peach trees, as well as lignin content.

Summary: Potassium (K+) plays a crucial role in plant homeostasis, and its deficiency significantly impacts photosynthesis and crop production. Under potassium starvation, multiple factors interact to reduce the photosynthetic rate and crop growth. The application of exogenous potassium can improve plant tolerance to abiotic stresses and limit the production of reactive oxygen species through activation of the antioxidant system.

Summary: The potato is a widely cultivated and consumed crop worldwide, with its economically valuable swollen stolonic region containing abundant carbohydrates and modest quantities of minerals and vitamins. Tuber formation is regulated by various factors, including light, oxygen concentration, photosynthate availability, phytochromes, transcription factors, and metabolite availability. This review provides an update on our understanding of the involvement of these variables in the process of tuberization. Tuber formation starts at the beginning of the supportive season under optimal light conditions, where phytochromes in leaves perceive the signal and trigger a series of reactions leading to starch accumulation in the tuber.

Summary: The increasing concentration of heavy metals (HMs) due to human activities is a serious problem, affecting plants along with other abiotic stresses. Meeting the nutritional demands of a growing population under these adverse conditions is crucial. Soil remediation of HMs is costly and unsustainable, but applying nanobionics to enhance plant stress tolerance shows promise. This review highlights the impact of nanobionics on plant physiological traits, growth indices, and discusses associated concerns and stress tolerance.

Summary: This study investigated the use of copper oxide nanoparticles (CuO NPs) as seed primers to enhance the growth of Brassica juncea. The results showed that seed priming with 4 mg/L CuO NPs for 30 minutes significantly increased the growth indices and biochemical parameters of B. juncea. Antioxidant enzyme activity and biochemical parameters were also enhanced. This suggests that CuO NPs can effectively improve the performance of B. juncea and may have potential in other crop species.
