Abiotic stresses are the foremost limiting factors for agricultural productivity. Crop plants need to cope up adverse external pressure created by environmental and edaphic conditions with their intrinsic biological mechanisms, failing which their growth, development, and productivity suffer. Microorganisms, the most natural inhabitants of diverse environments exhibit enormous metabolic capabilities to mitigate abiotic stresses. Since microbial interactions with plants are an integral part of the living ecosystem, they are believed to be the natural partners that modulate local and systemic mechanisms in plants to offer defense under adverse external conditions. Plant– microbe interactions comprise complex mechanisms within the plant cellular system. Biochemical, molecular and physiological studies are paving the way in understanding the complex but integrated cellular processes. Under the continuous pressure of increasing climatic alterations, it now becomes more imperative to define and interpret plant–microbe relationships in terms of protection against abiotic stresses. At the same time, it also becomes essential to generate deeper insights into the stress-mitigating mechanisms in crop plants for their translation in higher productivity. Multi-omics approaches comprising genomics, transcriptomics, proteomics, metabolomics and phenomics integrate studies on the interaction of plants with microbes and their external environment and generate multi-layered information that can answer what is happening in real-time within the cells. Integration, analysis and decipherization of the big-data can lead to a massive outcome that has significant chance for implementation in the fields. This review summarizes abiotic stresses responses in plants in-terms of biochemical and molecular mechanisms followed by the microbe-mediated stress mitigation phenomenon. We describe the role of multi-omics approaches in generating multi-pronged information to provide a better understanding of plant–microbe interactions that modulate cellular mechanisms in plants under extreme external conditions and help to optimize abiotic stresses. Vigilant amalgamation of these high-throughput approaches supports a higher level of knowledge generation about root-level mechanisms involved in the alleviation of abiotic stresses in organisms. © 2017 Meena, Sorty, Bitla, Choudhary, Gupta, Pareek, Singh, Prabha, Sahu, Gupta, Singh, Krishanani and Minhas.
Micro-level assessment of agricultural vulnerability to climate variability in Mirzapur District, Uttar Pradesh

The variation in climatic parameters like temperature, precipitation and humidity significantly influences agricultural ecosystem and human societies by affecting crop yield, cropping pattern and overall agricultural practices. Understanding agricultural vulnerability to these variations is crucial for preventing long-term consequences such as food security, changing human settlement patterns and economic instability. Thus, this study attempted to study micro level vulnerability in agriculture in Mirzapur district of Uttar Pradesh. The study aimed to introduce Agriculture Vulnerability Index (AVI) and evaluate the farmer perception about climate change and significant impact on agriculture utilising both primary and secondary data. The primary data was collected from 240 respondent using multistage random stratified sampling. The AVI was computed utilising Shannon Information Entropy method based on four indicators such as exposure to climatic variability, exposure, sensitivity, and adaptive capacity divided into 23 indicators. Ground Water Extraction (17.03%), Agricultural Wasteland (9.92%), Rural population (7.30%), and Barren land (6.21%) disproportionately influenced the agricultural vulnerability. The findings of the study revealed significant variation in agricultural vulnerability in which Hallia, Kon, Nagar, and Pahari block were found to be severely vulnerable to climatic variation. The farmers opinion revealed that the study area is experiencing erratic climatic variation like unseasonal rains and droughts causing serious distress to them. The agricultural landscape has undergone a notable transformation, characterized by a transition to a rice–wheat-gram cropping system, primarily facilitated by enhanced irrigation infrastructure as observed from primary survey. The farmers are compelled to revert to their old system of millet-gram-wheat cropping system due to increased ground water exploitation and present climatic variability. The research underscores the critical imperative of implementing agricultural diversification strategies, drought-resistant crop varieties, micro-irrigation, or policy incentives to mitigate climate vulnerability and improve food sustainability. The study reinforces the farmers opinion-based research to integrate indigenous knowledge system with conventional science-based knowledge to enhance resilience and ensure agricultural development at the micro level. © The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature 2025.
