With the growing human population worldwide, innovative agricultural development is needed to meet food security needs. However, this has inadvertently led problematic irrigation practices and overuse of agrochemicals. Such can exacerbate soil salinization, which prevents plant growth. As a progressively widespread escalating problem, salinization poses major threat global security. Compared with traditional use microalgae or microorganisms that act on growth, microalgae-microorganism symbiosis significant advantages in promoting Microalgae work together provide wide range nutrients required by plants, they exhibit nutrient complementarity, supports Here, potential microalgae-microbial for enhancing salt tolerance was investigated. Our review demonstrated metabolic complementarity between enhance tolerance. The diversity symbiotic system improve ecosystem stability resistance reduce incidence disease under stress. These systems produce bioactive substances (e.g., phytohormones) promote crop yield, structure increasing organic matter improving water storage capacity fertility.
