Seed priming: an emerging tool towards sustainable agriculture

Seed germination is one of the most crucial and complex physiological phenomena in the lifecycle of a plant, which often falls prey to environmental and biological stress that leads to erratic germination. Priming is a traditional method, generally used for synchronized seedling growth and stable crop stand, but priming has emerged as a potent tool for sustainable agriculture in recent times. It is used to tide over many abiotic stresses, such as salinity, drought, cold, heavy metal stresses, and also escalate the growth of the crop plants. Priming is even found to be beneficial against biotic stress agents like pathogenic bacteria and fungi. In this review, we have tried to summarize different successful reports of priming that had brought remarkable results in terms of growth, yield, disease resistance, abiotic and biotic stress tolerance. It also identifies the subcellular changes induced by priming highlighting the molecular and physiological aspects. The specific proteomic changes during imbibition and seed dehydration processes associated with a priming that helps in uplifting the seed vigor are also summarized. In the wake of the soaring demand of the food supply due to continuous surge in population and excessive use of chemical fertilizers to achieve higher yield, soil health is compromised. As an alternative, seed priming can serve as a cost-effective, environment-friendly, and pragmatic approach to address global food security through sustainable agricultural innovation. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
