    (Frontiers Media S.A., 2021) Singhal, Rajesh K.; Saha, Debanjana; Skalicky, Milan; Mishra, Udit N.; Chauhan, Jyoti; Behera, Laxmi P.; Lenka, Devidutta; Chand, Subhash; Kumar, Vivek; Dey, Prajjal; Indu; Pandey, Saurabh; Vachova, Pavla; Gupta, Aayushi; Brestic, Marian; El Sabagh, Ayman
    In the era of rapid climate change, abiotic stresses are the primary cause for yield gap in major agricultural crops. Among them, salinity is considered a calamitous stress due to its global distribution and consequences. Salinity affects plant processes and growth by imposing osmotic stress and destroys ionic and redox signaling. It also affects phytohormone homeostasis, which leads to oxidative stress and eventually imbalances metabolic activity. In this situation, signaling compound crosstalk such as gasotransmitters [nitric oxide (NO), hydrogen sulfide (H2S), hydrogen peroxide (H2O2), calcium (Ca), reactive oxygen species (ROS)] and plant growth regulators (auxin, ethylene, abscisic acid, and salicylic acid) have a decisive role in regulating plant stress signaling and administer unfavorable circumstances including salinity stress. Moreover, recent significant progress in omics techniques (transcriptomics, genomics, proteomics, and metabolomics) have helped to reinforce the deep understanding of molecular insight in multiple stress tolerance. Currently, there is very little information on gasotransmitters and plant growth regulator crosstalk and inadequacy of information regarding the integration of multi-omics technology during salinity stress. Therefore, there is an urgent need to understand the crucial cell signaling crosstalk mechanisms and integrative multi-omics techniques to provide a more direct approach for salinity stress tolerance. To address the above-mentioned words, this review covers the common mechanisms of signaling compounds and role of different signaling crosstalk under salinity stress tolerance. Thereafter, we mention the integration of different omics technology and compile recent information with respect to salinity stress tolerance. � Copyright � 2021 Singhal, Saha, Skalicky, Mishra, Chauhan, Behera, Lenka, Chand, Kumar, Dey, Indu, Pandey, Vachova, Gupta, Brestic and El Sabagh.

    Drought stress responses and inducing tolerance by seed priming approach in plants
    (Elsevier B.V., 2022) Saha, Debanjana; Choyal, Prince; Mishra, Udit Nandan; Dey, Prajjal; Bose, Bandana; MD, Prathibha; Gupta, Narendra Kumar; Mehta, Brijesh Kumar; Kumar, Pawan; Pandey, Saurabh; Chauhan, Jyoti; Singhal, Rajesh Kumar
    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

    Molecular advances in plant root system architecture response and redesigning for improved performance under unfavorable environments
    (Elsevier, 2021) Indu; Lal, Dalpat; Dadrwal, Basant Kumar; Saha, Debanjana; Chand, Subhash; Chauhan, Jyoti; Dey, Prajjal; Kumar, Vivek; Mishra, Udit Nandan; Hidangmayum, Akash; Singh, Ankita; Singhal, Rajesh Kumar
    A future challenge in crop improvement, mostly driven by global unfavorable environment variables, is to develop climate smart crops that are competent for multiple biotic and abiotic stresses. Researchers have addressed the elementary mechanism focused on aboveground plant organs, as extensive study on root traits are very confined. Moreover, most of our knowledge regarding root research is limited to certain developmental aspects, while a direct connectivity to developing environment sensitive roots under various stresses is extremely urgent to explore thoroughly. Therefore this chapter covers the most recent research on the root system architecture (RSA) of different crop species with regard to different extreme environmental variables such as high temperature, elevated CO2, low temperature, drought, excess water, and stressed soil. We highlight the recent physiological, genetic, and molecular strategies used in the rapid advancement of RSA traits under these stresses. There is an urgent need to explore RSA in order to improve crop stress tolerance, therefore we discuss and explore the link between RSA and stress tolerance. Further, this chapter will provide new insights into the relevance of the redesign and selection of improved RSA for the development of climate resilient plants. We conclude by discussing the functional and molecular evidence of RSA components such as deep root weight, root length density, root volume, root penetration, and other root traits for improving root plasticity in a fluctuating environment, which will help the researchers to select RSA pipelines for abiotic stress resilience and crop improvement programs. � 2021 Elsevier Inc.

    Physiological, biochemical, and molecular adaptation mechanisms of photosynthesis and respiration under challenging environments
    (Elsevier, 2021) Dey, Prajjal; Datta, Diptanu; Pattnaik, Debasish; Dash, Deepali; Saha, Debanjana; Panda, Darshan; Bhatta, Bishal Binaya; Parida, Selukash; Mishra, Udit Nandan; Chauhan, Jyoti; Pandey, Himanshu; Singhal, Rajesh Kumar
    Photosynthesis and respiration are two central and basic physiological processes in regulation to carbon budget and carbon sink in the terrestrial ecosystem, as well as assessment and feedback of highly variable and fluctuating environmental conditions. Elevated CO2, salinity, alkalinity, drought, flood, nutrient deficiency and toxicity, extreme cold and heat, and various natural and anthropogenic pollutants are critical challenges in near future and their primary target is to alteration of photosynthetic and respirational processes, which ultimately influence the final yield potential of major agricultural crops. However, plants adapt themselves to these environmental circumstances via complicated changes at physiochemical and molecular levels. The current chapter highlights the underline mechanisms of photosynthetic and respiration in response to climate change at physiological, biochemical, and molecular levels. This chapter also covers the timely and substantial information regarding the recent progress in photosynthesis and respiration research. First, an outline of future climate change and its impacts on plant processes, functions, and yield potential is presented. Then, responses and adaptation of photosynthesis and respiration mechanisms against multiple stresses are discussed. Globally the present issues are crucial and this chapter helps in better understanding how plants deal with climatic change and their physiological, cellular, and molecular processes to the development of sustainable environment. � 2022 Elsevier Inc.

    Plant photosynthesis under abiotic stresses: Damages, adaptive, and signaling mechanisms
    (Elsevier B.V., 2023) Chauhan, Jyoti; Prathibha, M.D.; Singh, Prabha; Choyal, Prince; Mishra, Udit Nandan; Saha, Debanjana; Kumar, Rajeev; Anuragi, Hirdayesh; Pandey, Saurabh; Bose, Bandana; Mehta, Brijesh; Dey, Prajjal; Dwivedi, K.K.; Gupta, N.K.; Singhal, Rajesh Kumar
    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
