Proteins are direct function performers in organisms, and changes in protein content play a crucial role in organism study. Metabolites are closely related to physiological phenotypes, and changes in metabolites in organisms can explore the metabolic mechanism of the whole organism by detecting changes in metabolites after exogenous stimuli or genetic modifications; moreover, comprehensive analysis of products in the life process of organisms can help to reveal the link between genotypes and phenotypes. Therefore, in order to comprehensively investigate the disease and stress mechanisms of organisms, and precisely study the expression patterns and regulatory mechanisms of important genes, only by integrating transcriptomics,proteomics, andmetabolomicsdata and conducting multifaceted studies on biological samples can we uncover the molecular regulatory mechanisms of the life process, and then explain the biological problems from a holistic point of view.

The use of metabolomics integrated with transcriptomic and proteomic studies for identifying key steps involved in the control of nitrogen metabolism in crops such as maize.

Journal: J Exp Bot

Published: 2012

Abstract

Linking plant phenotypes to gene and protein expression and metabolite synthesis and accumulation is one of the major challenges for improving global agricultural production. This challenge is particularly relevant to crop nitrogen utilization efficiency (NUE). In this article, the authors investigated differences in the accumulation of gene transcripts, proteins, and metabolites in maize leaves under long-term nitrogen (N)-deficient growing conditions at two important stages of plant development. The effects of nitrogen deficiency were examined at the transcriptomic, proteomic, and metabolomic levels. By integrating transcriptomic,proteomic, andmetabolomic data analyses, the authors contribute to improving researchers' understanding of plant nitrogen economics for better application in breeding and agronomy.

Results

The leaf proteome was not significantly altered functionally under chronic nitrogen deficiency. Comparison of the proteomes of N- and N+ leaves at the nutrient V stage revealed significant differences (P < 0.05) in the volumes of 45 protein spots. Only 40 proteins were identified. Quantification of the optical density of these differences is shown in JXB Online Supplemental Table S3. At the M maturation stage, the volume of 40 protein spots was significantly altered in N-deficient leaves. Examples of modifications occurring in leaf protein profiles show differences between V-stage N+ and N- plants ( Figure 1).

Figure 1Figure 1

Functional classes of metabolites, proteins and gene transcripts isolated from leaves of maize plants grown under low and high nitrogen fertilization conditions showed differences in accumulation levels. Pie charts show the number of metabolites, proteins, and transcripts identified in the three "omics" experiments, which increased at the nutrient (V) and maturity (M) stages of leaf development under either high (N+) or low (N-) nitrogen supply ( Figure 2).

Conclusion

The authors found that many key plant biological functions were either up- or down-regulated when N was limited, including major alterations in photosynthesis, carbon (C) metabolism, and to a lesser extent downstream metabolic pathways. The authors also found that the effects of N deficiency stress were similar to plant responses to many other biotic and abiotic stresses in terms of transcript, protein, and metabolite accumulation. Genetic and metabolic changes differed between the nitrogen assimilation and irrigation phases, suggesting that plant development is an important component in determining the key elements of the control of nitrogen use efficiency in plants. The integration of the three "omics" studies is not straightforward, as the different levels of regulation appear to occur in a stepwise manner from gene expression to metabolite accumulation.
