Summary: This study evaluated the effects of exogenous proline application on the ionomic profile of tobacco plants and found that proline application significantly affected the ionomic profile, rather than the water regime. The absorption and translocation mechanisms were likely affected by the higher amount of proline, leading to the separation of mineral elements into different groups. Ultimately, the data suggests that proline may act as a mitigator of nutritional deficiencies caused by water deficit conditions in tobacco plants.

Summary: The molecule nitric oxide (NO) plays a crucial role in plant physiology and biological processes, especially in response to abiotic and biotic stresses. It interacts with various signaling networks to regulate stress tolerance in plants. Greenhouse gases (GHGs), including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3), have been found to trigger similar signaling pathways in plants as commonly studied abiotic stresses. This review focuses on the role of NO signaling and its interaction with calcium and hormonal signaling pathways under elevated GHGs levels, and explores the mechanisms underlying GHGs-induced stress in plants.

Summary: Seed germination plays a significant role in plant development and crop yield. Recent studies have found that nitric oxide (NO) acts as both a nitrogen source during seed development and a participant in stress responses to salt, drought, and high temperature. NO influences seed germination by integrating various signaling pathways. However, the precise network mechanism of NO's regulation of seed germination is still unclear due to the instability of NO gas activity.

Summary: Plant defense and growth depend on multiple transcriptional factors, including the Repression of shoot growth (RSG) protein. In this study, researchers identified the protein kinase NtMPK3 as an interacting partner of RSG in tobacco. The phosphorylation of specific sites on RSG by NtMPK3 was found to regulate the intracellular localization of RSG and affect its function in the plant's response to plant defense elicitors.

Summary: Manipulating the mole fractions of CO2 and O-2 during gas exchange experiments has a broad impact on metabolism beyond just carboxylation and oxygenation pathways. Non-targeted metabolic analyses have shown changes in tricarboxylic acid cycle, anaplerosis, and nitrogen or sulphur assimilation pathways as a result. This approach has also revealed significant alterations in branched chain amino acids, phenylpropanoid metabolism, and adenosine turnover, all of which involve CO2 assimilation or liberation and affect net CO2 exchange.

Summary: Polyamines (PAs) play crucial roles in growth, development, and stress responses in plants. Exogenous applications of Spm and Spd induced cell death at high concentrations but primed resistance against Botrytis cinerea. Both Spm and Spd triggered the accumulation of antioxidant enzymes and soluble sugars, while inhibiting nitrate reductase activities. This suggests the potential of using Spm and Spd as sustainable alternatives to chemical pesticides.

Summary: This study examined the impact of nitrogen source on the susceptibility to an necrotrophic fungus in Arabidopsis thaliana. The results showed that nitrate nutrition increased fungal lesions considerably, while infection with the fungus induced stronger gene expression of ammonium transporters in ammonium-grown plants. Nitrogen source also affected plant metabolism and the production of nitric oxide, which facilitated fungal infection. The study highlighted the complex relationship between nitrogen availability and disease susceptibility in plants.

Summary: Nitrate is not only a necessary nutrient for plants, but also a signal involved in plant development. This study investigated the role of MtNPF6.8, a nitrate transporter, in regulating root growth and identified the POD isoforms responsible for changes in POD activity. It was found that MtNPF6.8 is a master mediator of the nitrate signal and its integrity is crucial for the sensitivity of the root tip to nitrate. Additionally, transcriptomic and proteomic analysis revealed the genes and proteins that respond to nitrate and provided insights into the changes in POD activity.

Summary: Seed size is an important trait for seed quality, reflecting the quantity of reserve material available for post-germinative processes. This study examined seed size and composition in different accessions of Medicago truncatula and found that N content increased and H content decreased with seed size. Metabolomic analysis showed that seed size correlated with free amino acid and hexoses content, and anticorrelated with amino acid degradation products, disaccharides, malic acid, and free fatty acids. The results suggest that seed size is determined by metabolic balance and may be influenced by phloem source metabolite delivery during seed development.

Summary: Legumes are suitable for sustainable agroecosystems due to their ability to fix atmospheric nitrogen through symbiotic nitrogen fixation (SNF). In this study, we investigated whether signals derived from Rhizobium interfere with nitrate signaling in pea plants. Our results showed that Rhizobium-altered nitrate-mediated processes affected the expression of major genes involved in nitrate transport, sensing, and signaling. Additionally, the characteristic limitation of root foraging and branching response to nitrate supply was abolished in infected peas. The findings suggest that Rhizobium allows for favorable management of trade-offs between nodules growth and root foraging in pea plants. These results can be used to develop molecular tools for breeding pea genotypes with deep-foraging and branched root systems without compromising nodulation.

Summary: Plants exposed to extreme climatic conditions have a disrupted balance between energy absorption and processing. Variegated leaves provide a model system to study source-sink interactions in the same leaf. Under excess excitation energy conditions, metabolic reprogramming occurs in both green leaf tissue and white leaf tissue, allowing increased consumption of reducing equivalents. The white leaf tissue acts as an energy escape valve to maintain the successful performance of the green leaf tissue.

Summary: Phloem sap transport plays a crucial role in plant nutrition and development by redistributing nutrients, metabolites, and signaling molecules. However, its biochemical composition is not well-studied due to the difficulty in sampling and analyzing phloem sap. Recent metabolomics studies using liquid or gas chromatography coupled with mass spectrometry have provided insights into the phloem sap metabolome and its physiological implications. These studies show that phloem sap contains not only sugars and amino acids but also diverse metabolic pathways. They also suggest that metabolic exchange between source and sink organs is a common phenomenon, contributing to whole-plant metabolic cycles and shoot-root coordination of growth and development.

Summary: By analyzing previously published data on yield, respiration, carbon isotope composition, nitrogen content, and water consumption in winter wheat cultivars grown under different irrigation conditions, we found that phloem sucrose transport rate is closely related to phloem nitrogen transport rate and mainly depends on grain weight. The velocity of phloem sap or its proportionality coefficient to xylem velocity changes little with environmental conditions. Overall, phloem transport from leaves to grains appears to be homeostatic within a narrow range and follows relationships with other plant physiological parameters. This suggests that phloem transport itself is not a limitation for yield in wheat, but rather it is regulated to sustain grain filling.

Summary: This opinion article analyzes the hypothesis that the jasmonic acid (JA)-mediated defense system against necrotrophic fungi in Arabidopsis thaliana is weakened when there is a high supply of NO3-. The study suggests that the increase in bioactive ABA induced by high NO3- supply can disrupt the phosphorylation of NO3- and K+ transporters, leading to a weakened defense system against necrotrophic fungi.
