Taking into consideration, the challenges faced by the environment and agro-ecosystem make increased for suggestions more reliable methods to help increase food security and deal with difficult environmental problems. Environmental factors play a critical role in the growth, development, and productivity of crop plants. Unfavorable changes in these factors, such as abiotic stresses, can result in plant growth deficiencies, yield reductions, long-lasting damage, and even death of the plants. In reflection of this, cyanobacteria are now considered important microorganisms that can improve the fertility of soils and the productivity of crop plants due to their different features like photosynthesis, great biomass yield, ability to fix the atmospheric N capability to grow on non-arable lands, and varied water sources. Furthermore, numerous cyanobacteria consist of biologically active substances like pigments, amino acids, polysaccharides, phytohormones, and vitamins that support plant growth enhancement. Many studies have exposed the probable role of these compounds in the alleviation of abiotic stress in crop plants and have concluded with evidence of physiological, biochemical, and molecular mechanisms that confirm that cyanobacteria can decrease the stress and induce plant growth. This review discussed the promising effects of cyanobacteria and their possible mode of action to control the growth and development of crop plants as an effective method to overcome different stresses.
考虑到环境和农业生态系统面临的挑战，人们越发需要更可靠的方法来帮助提高粮食安全并应对棘手的环境问题。环境因素对农作物的生长、发育和生产力起着关键作用。这些因素的不利变化，如非生物胁迫，会导致植物生长不足、产量降低、长期损害甚至植物死亡。鉴于此，蓝藻细菌现在被认为是重要的微生物，由于其光合作用、高生物量产量、固氮能力、在非耕地上生长的能力以及多样的水源等不同特性，它们可以提高土壤肥力和农作物生产力。此外，许多蓝藻细菌含有色素、氨基酸、多糖、植物激素和维生素等生物活性物质，这些物质有助于促进植物生长。许多研究揭示了这些化合物在缓解农作物非生物胁迫方面的潜在作用，并通过生理、生化和分子机制的证据得出结论，证实蓝藻细菌可以减轻胁迫并促进植物生长。本综述讨论了蓝藻细菌的积极作用及其控制农作物生长发育的可能作用方式，作为克服不同胁迫的有效方法。
