Mineral nutrients in plants under changing environments: A road to future food and nutrition security

Abstract

Plant nutrition is an important aspect that contributes significantly to sustainable agriculture, whereas minerals enrichment in edible source implies global human health; hence, both strategies need to be bridged to ensure “One Health” strategies. Abiotic stress‐induced nutritional imbalance impairs plant growth. In this context, we discuss the molecular mechanisms related to the readjustment of nutrient pools for sustained plant growth under harsh conditions, and channeling the minerals to edible source (seeds) to address future nutritional security. This review particularly highlights interventions on (i) the physiological and molecular responses of mineral nutrients in crop plants under stressful environments; (ii) the deployment of breeding and biotechnological strategies for the optimization of nutrient acquisition, their transport, and distribution in plants under changing environments. Furthermore, the present review also infers the recent advancements in breeding and biotechnology‐based biofortification approaches for nutrient enhancement in crop plants to optimize yield and grain mineral concentrations under control and stress‐prone environments to address food and nutritional security.

The Effect of Renewable Phosphorus Biofertilizers on Selected Wheat Grain Quality Parameters

“…This could be attributed to the fact that P application stimulates root development, more intensive plant uptake of other nutrients as well as their translocation, assimilation and accumulation of assimilates in the grain [6,7,9], leading to the observed stability in yield quality. According to current knowledge, plants use a variety of molecular, physiological, and ecological mechanisms to maintain nutrient homeostasis [68,69].…”

Optimizing Nitrogen Application for Enhanced Barley Resilience: A Comprehensive Study on Drought Stress and Nitrogen Supply for Sustainable Agriculture

“…This includes crucial enzymes like superoxide dismutase and catalase, which play a role in mitigating the stress associated with deficit irrigation [10]. Nitrogen serves as a regulator influencing the impact of short-term heat, drought, and combined stresses on diverse aspects of wheat physiology, encompassing photosynthesis, yield, nitrogen metabolism, and nitrogen use efficiency [11,12].…”

Ameliorating heat stressed conditions in wheat by altering its physiological and phenotypic traits associated with varying nitrogen levels

“…Plants need adequate and proper supply of mineral nutrients for driving essential physiological processes and maintaining their structural stability (Hassan et al, 2020). Nutrients are a vital components of different plant systems and play important role in coordination of several developmental and physiological processes in plants such as respiration, photosynthesis, root and shoot growth, seed germination and flower development (Khan et al, 2023). Moreover, exogenous applications of certain minerals are also involved in improving heat tolerance in crop plant by regulating stomatal conductance and upregulation of metabolic and physiological processes (Khan et al, 2023).…”
