    Annexins: A family of calcium binding proteins with variety of roles in plant development and abiotic stress tolerance
    (Elsevier, 2024) Faizan, Mohammad; Ashoka, Hadagali; Karabulut, Fadime; Alam, Pravej; Ahmed, S. Maqbool; Khan, Ira; Soysal, Sipan
    Plant annexins are a multigene family of phospholipid-binding, calcium-dependent proteins that respond to signals and environmental challenges as plants grow and develop. Plant annexins are functionally unique due to their ATPase/GTPase, peroxidase, and calcium (Ca2+) channel-regulating activities. They play a major role in controlling many different aspects of cellular and metabolic functions, plant growth and development, and reactions to both biotic and abiotic environmental stimuli. In this review, we provide an overview of how intracellular and extracellular annexins work, mechanism of reactive oxygen species (ROS) and annexins, highlight recent developments of the roles of annexins in abiotic stress tolerance in plants, and emphasize the role of annexins in plant growth and development.

    Karrikins biosynthesis, signaling route, regulatory roles, and hormonal crosstalk in plant soil system
    (Natl Information Documentation Cent, Acad Scientific Research & Technology, 2024) Faizan, Mohammad; Rajput, Khushboo; Patyal, Urvasha; Kaur, Manpreet; Sanchan, Rohan Kumar; Alam, Pravej; Maruthi, Katenahalli Rudrappa
    Modern agriculture will face new obstacles, such as the increased frequency of forest and grassland fire outbreaks brought on by climate change, which will call for creative solutions. The chemicals known as karrikins are present in smoke produced by burning plant matter. Several additional known functions, including seed germination and other photo-morphogenetic processes, are linked to them. Nowadays, it is becoming clearer how KARs can improve plant performance in a variety of ecological limits. KARs not only regulate antioxidative metabolism (SOD, POX, GR, APX) but also up-regulate the expression of several stress-related genes in plants to reduce oxidative stress in plants brought on by biotic and abiotic factors. Plants have an intricate tolerance mechanism that includes stomatal pore management, systemic communication, redox equilibrium maintenance, and other functions to cope with abiotic stressors. In Arabidopsis thaliana, Karrikins signaling is mediated by the F-box protein MAX2, which also controls responses to the structurally related strigolactone family of phytohormones. This review paper goes into great detail about the discovery, biosynthesis, and signaling mechanism of karrikins as well as their interactions with other phytohormones and future prospects.

    Unraveling the nano-biochar mediated regulation of heavy metal stress tolerance for sustaining plant health
    (Elsevier B.V., 2024) Faizan, Mohammad; Alam, Pravej; Kumari, Asha; Suresh, Gali; Sharma, Priyanka; Karabulut, Fadime; Soysal, Sipan
    Heavy metal (HM) toxicity of agricultural soils poses a major risk to plant health, human life, and global food chain. Crop output and health are negatively impacted when HM levels in agricultural soils reach hazardous points. The nano-biochar (nano-BC) mediated stress tolerance has attracted growing scientific interest because biochar has the potential to be a novel and sustainable solution that may be actively included into the development of sustainable agriculture and food production. At present, biochar is extensively employed as a powerful tool to enhance sustainable agriculture with minimal impact on ecosystems and the environment. Nano-BC offers improved surface area, adsorption and mobility properties in soil compared to traditional fertilizers. Furthermore, nano-BC may prove to be the most practical substitute for traditional waste management techniques because of its affordability, sustainability, and environmental friendliness. In this review, we examine the application of nano-BC in the regulation of HM stress tolerance for improving plant growth and development. We focus on the impact of HMs impact on crop productivity, nano-BC amendments, their application, and production. The article also explores the nano-BC risk and toxicity. Through the perspective of multidisciplinary research, this work highlights the significance of nano-BC as cutting-edge tools in the field of agriculture, igniting a paradigm shift toward sustainable and stress-resilient farming systems. © 2024 The Author(s)
