Microalgae and Cyanobacteria have gathered immense importance as soil reclamator and enhancer of plant productivity leading to sustainable agricultural ecosystem. Multiple omics and meta-omics approaches, namely, genomic, transcriptomic, proteomic and metabolomic have widened their role due to the exploration of genetic elements, expression of genes under various ecological conditions, and increased understanding of functional mechanisms of algal soil interactions. Microalgae can enhance the soil conditioning by increasing the organic carbon content, nutrient solubilization, nitrogen fixation, and other metabolic compounds synthesis etc. Further microalgae inoculation enhances abiotic and biotic stress tolerance in plants due to several metabolites and genes offering resistance against various pathogens. Metabolomic approaches additionally unravel the synthesis of various compounds, lipids, carbohydrates, proteins, phytohormones and various phenol compounds that improve the soil composition and structure. This chapter thus explores the sustainable algal applications in the agricultural field with multiomics and metaomics approaches for optimizing gene expression, proteins, and metabolites in microalgae.

摘要

Microalgae and Cyanobacteria have gathered immense importance as soil reclamator and enhancer of plant productivity leading to sustainable agricultural ecosystem. Multiple omics and meta-omics approaches, namely, genomic, transcriptomic, proteomic and metabolomic have widened their role due to the exploration of genetic elements, expression of genes under various ecological conditions, and increased understanding of functional mechanisms of algal soil interactions. Microalgae can enhance the soil conditioning by increasing the organic carbon content, nutrient solubilization, nitrogen fixation, and other metabolic compounds synthesis etc. Further microalgae inoculation enhances abiotic and biotic stress tolerance in plants due to several metabolites and genes offering resistance against various pathogens. Metabolomic approaches additionally unravel the synthesis of various compounds, lipids, carbohydrates, proteins, phytohormones and various phenol compounds that improve the soil composition and structure. This chapter thus explores the sustainable algal applications in the agricultural field with multiomics and metaomics approaches for optimizing gene expression, proteins, and metabolites in microalgae.
