Special Issue Information

Dear Colleagues,

Carbon and nitrogen are the most important essential elements constituting the organic compounds in plants. Carbohydrates (i.e., sugars, starches, and cell wall polysaccharides) are mostly composed of C, H, and O; and proteins and nucleic acids consist of C, H, O, and N. Terrestrial plants are photoautotrophs turn carbon dioxide into sugar by using light energy and water in the leaves. At the same time, plants absorb nitrogen from the soil, mainly in the form of nitrate or ammonium for their posterior incorporation into amino acids, and hence for the synthesis of protein. Several microorganisms fix nitrogen symbiotically by partnering with a host plant. The shoots and roots depend on each other by exchanging the C and N through xylem and phloem transport systems. C and N metabolism are regulated by complex mechanisms in order to optimize plant growth, agricultural crop production, and the maintenance of agro- and natural-ecosystem. The up-to-date review articles are welcomed as well as original regular papers.

This Special Issue aims to shed light on cutting-edge research of:

  • The molecular basis of carbon and nitrogen metabolism and their regulation.
  • Integrated networks using multiple omics for understanding C and N metabolisms under normal and/or biotic and abiotic stresses in plants. Only-omics approaches providing further insights into C and N regulation will be considered for review.
  • The interaction of C and N metabolism, transport, and storage.
  • Insights into the interaction and regulation of carbon and nitrogen metabolisms within the plant–microorganism communication.
  • The signal transductions related to phytohormones, signal peptide, and non-coding RNA.
  • Agricultural and ecological aspects based on molecular approaches will be welcome.

Physiological, Hormonal and Metabolic Responses of two Alfalfa Cultivars with Contrasting Responses to Drought

Alfalfa (Medicago sativa L.) is frequently constrained by environmental conditions such as drought. Within this context, it is crucial to identify the physiological and metabolic traits conferring a better performance under stressful conditions. In the current study, two alfalfa cultivars (San Isidro and Zhong Mu) with different physiological strategies were selected and subjected to water limitation conditions. Together with the physiological analyses, we proceeded to characterize the isotopic, hormone, and metabolic profiles of the different plants. According to physiological and isotopic data, Zhong Mu has a water-saver strategy, reducing water lost by closing its stomata but fixing less carbon by photosynthesis, and therefore limiting its growth under water-stressed conditions. In contrast, San Isidro has enhanced root growth to replace the water lost through transpiration due to its more open stomata, thus maintaining its biomass. Zhong Mu nodules were less able to maintain nodule N2 fixing activity (matching plant nitrogen (N) demand). Our data suggest that this cultivar-specific performance is linked to Asn accumulation and its consequent N-feedback nitrogenase inhibition. Additionally, we observed a hormonal reorchestration in both cultivars under drought. Therefore, our results showed an intra-specific response to drought at physiological and metabolic levels in the two alfalfa cultivars studied. Full article

An Integrated Analysis of the Rice Transcriptome and Metabolome Reveals Differential Regulation of Carbon and Nitrogen Metabolism in Response to Nitrogen Availability

Nitrogen (N) is an extremely important macronutrient for plant growth and development. It is the main limiting factor in most agricultural production. However, it is well known that the nitrogen use efficiency (NUE) of rice gradually decreases with the increase of the nitrogen application rate. In order to clarify the underlying metabolic and molecular mechanisms of this phenomenon, we performed an integrated analysis of the rice transcriptome and metabolome. Both differentially expressed genes (DEGs) and metabolite Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated that carbon and nitrogen metabolism is significantly affected by nitrogen availability. Further analysis of carbon and nitrogen metabolism changes in rice under different nitrogen availability showed that high N inhibits nitrogen assimilation and aromatic metabolism pathways by regulating carbon metabolism pathways such as the tricarboxylic acid (TCA) cycle and the pentose phosphate pathway (PPP). Under low nitrogen, the TCA cycle is promoted to produce more energy and α-ketoglutarate, thereby enhancing nitrogen transport and assimilation. PPP is also inhibited by low N, which may be consistent with the lower NADPH demand under low nitrogen. Additionally, we performed a co-expression network analysis of genes and metabolites related to carbon and nitrogen metabolism. In total, 15 genes were identified as hub genes. In summary, this study reveals the influence of nitrogen levels on the regulation mechanisms for carbon and nitrogen metabolism in rice and provides new insights into coordinating carbon and nitrogen metabolism and improving nitrogen use efficiency in rice.
