摘要

光合作用是一种特殊的机制，它形成了地球上的生命，并为所有已知的生命创造了条件。近几十年来，钙（Ca）作为植物次生信使的功能一直是大量研究的主题。由于它们的无根性，植物受到各种非生物胁迫，如农药污染、重金属、盐、干旱、营养缺乏、光照强度和高温。非生物胁迫主要对植物的气体交换参数、电子传递过程、光系统性能和叶绿素产生不利影响，从而降低植物的光合效率。这些胁迫导致植物光合能力的下降与产量的降低直接相关。因此，详细了解钙（Ca）和纳米Ca在光合机制中的作用，更好地了解光合机制，有助于在逆境环境下开发更高产量的新策略。有趣的是，在这篇综述中，我们概述了非生物胁迫下影响光合作用的机制。本文综述了几种非生物胁迫对植物光合作用机制的负面影响，以及钙和纳米钙在植物光合作用中的调节作用。这篇综述还强调了使用纳米ca提高光合效率的优势。

Untapped potential of calcium and nano-calcium to develop abiotic stress resilience in photosynthetic machinery: The primary source of plant food and fuels

Photosynthesis is a special mechanism that has formed life on earth and created the conditions for all known life. The function of calcium (Ca) as a secondary messenger in plants has been the subject of substantial research in recent decades. Due to their sessile nature, plants are subject to a variety of abiotic stresses, such as pesticide pollution, heavy metals, salt, drought, nutrient deficiencies, light intensity, and severe temperatures. Abiotic stresses mainly lower plants' photosynthetic efficiency because they have detrimental effects on gas exchange parameters, electron transport processes, photosystem performance, and chlorophyll production. The decline in photosynthetic capacity of plants due to these stresses is directly associated with reduction in yield. Therefore, detailed information of the role of calcium (Ca) and nano-Ca on photosynthetic machinery and better understanding of the photosynthetic machinery could help in developing new strategies with higher yield even under stressed environments. Interestingly, in this review, we provide an overview of insight into mechanism affecting photosynthesis under abiotic stresses. The present review explains how several abiotic stressors can negatively affect the photosynthesis mechanism and Ca and nano-Ca mediated-regulation in plant photosynthesis. The review also highlights the advantages of using nano-Ca to increase photosynthetic efficiency.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
