Plant requires seventeen essential mineral elements for proper growth and functioning classified as macro and micro-nutrients. Apart from these, cerium (Ce), cobalt (Co), iodine (I), aluminum (Al), selenium (Se), sodium (Na), lanthanum (La), silicon (Si), titanium (Ti), and vanadium (V) are evolving as pivotal bio-stimulants in plant growth and providing stress tolerance. Although, they are not mandatory for all plants directly but when they are supplemented, promote the plant growth positively and simulate multiple abiotic and biotic stresses tolerance. Though, these elements have crucial role in plant growth, still obscurethe uptake, transport and molecular understanding as much of macro and micronutrients. However, in recent years scientists are giving more emphasis to explore their mechanisms associated with enhancing antioxidant defense, stress responsive proteins accumulation, and transcription factors under variety of stresses. Likely, they are also crosstalk with other essential elements and plant growth regulators (PGRs) (salicylic acid, SA; jasmonic acid, JA), which is crucial for signaling network perception and regulate plant growth. Recent technologies developed in the field of nanotechnology assist in the further understanding of their uptake, transport and functions at cellular level andoptimizing their concentrations for better plant growth. Bio-fortification of crops with beneficial elements provides some cues regarding their importance in plant growth and also in human balance nutrition. To considering the importance of these compound, this review aimed to explore the uptake and transport mechanisms of beneficial elements and their function in plant development. Consequently, we pinpoint the crosstalk’s between PGRs and other mineral elements, which advance their crucial role during plant mineral nutrition and growth signaling. At the end, this review focused on the crucial role and mechanisms associated with these elements under multiple abiotic stresses that open exciting avanues in several directions related to crop stress breeding program. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.

Field crops are subjected to drought at different growth stages and cause for substantial yield loss in major crops, thus threaten to global food security. The crop researcher have evaluated numerous physiological, biochemical and molecular strategies to combat drought stresses but these approaches are not enough in present scenario. Therefore, it is argued that plants can be primed by assorted organic and in-organic promoters for excelling fortitude under stress conditions. Hence, seed priming with different agents is an auspicious area of research in stress biology and crop stress management, for conferring tolerance when plants are subjected to drought stress. However, the adaptation and tolerance mechanisms of drought stress are complex and quantitative in nature, which have been explored at physiological, biochemical and molecular levels thoroughly in this review. The concept of stress memory and its implication in future generation has also been discussed. Finally, in this review the challenges and opportunities of seed priming with effective application in crop stress management along with expanding the knowledge on deep understanding of drought stress tolerance to reduce the future yield gap are discussed thoroughly. © 2022

Photosynthesis is crucial for sustaining life on this planet and necessary for plant growth and development. Abiotic stresses such as high and low temperatures, and excess, or deficit of water limit the crucial plant processes, thus threatening the global food security. However, recent molecular approaches allowed elucidation of the photosynthetic components/compounds and their efficiency under stress conditions. In the present scenario, these approaches are not enough to reduce the yield penalty due to the reduction in photosynthetic efficiency. Therefore, comprehensive data on plant behavior and stress crosstalk networks could assist in understanding the in-depth mechanism of photosynthesis. In recent years, information regarding crosstalk, signaling characterization of candidate genes, and responses to multiple stressors have advanced our knowledge to understand the mechanism of photosynthesis. Therefore, in this review, we provide a comprehensive overview of various studies conducted on photosynthesis under multiple abiotic stress factors that affect the photosynthetic efficiency of a plant. We also discuss the role of crosstalk signaling compounds (plant growth regulators and micro RNAs) for an in-depth understanding of the photosynthesis mechanism. Finally, based on our gathered data set, the mechanism of damage and adaptive response of photosynthesis under multiple stressors are explained to enhance the scientific community's knowledge toward boosting photosynthesis and to accelerate stress tolerance strategies for crop improvement. © 2023
