Deciphering nutrient stress in plants: integrative insight from metabolomics and proteomics

To comprehend the responses and resilience of plants under unfavorable environmental conditions, it is crucial to study the metabolomics and proteomic insights into nutrient stress. Nutrient stress substantially challenges agriculture, impacting plant growth, development, and productivity due to a lack or imbalance of essential nutrients, which can happen due to poor soil quality, limited nutrient availability, or unfavorable climatic conditions. Although there has been significant progress in the study of plant nutrient stress using metabolomics and proteomics, several challenges and research gaps still need to be addressed, such as the standardized experimental protocols, data integration strategies, and bioinformatic tools are necessary for comparative analysis and interpretation of omics data. Hence, this review explores the theoretical frameworks of metabolomics and proteomics as powerful tools to decode plant responses to nutrient stress, addressing critical knowledge gaps in the field. This review highlights the advantages of integrative analyses, combining metabolomics, proteomics, and transcriptomics, to uncover the molecular networks governing nutrient stress resilience. Key findings underscore the potential of these techniques to enhance breeding strategies and genetic engineering efforts aimed at developing nutrient-efficient crops. Through metabolomics and proteomic analyses, novel molecular components and regulatory networks have been revealed as responsive to nutrient stress, and this breakthrough has the potential to bolster plant resilience and optimize nutrient utilization. Understanding the synergistic roles of metabolites and proteins in nutrient stress resilience has profound implications for crop improvement and agricultural sustainability. Future research should focus on refining integrative methodologies and exploring their applications across diverse plant species and environmental conditions, paving the way for innovative solutions to nutrient stress challenges.
