Abstract
Phytoliths, the microscopic silica structures formed within plant tissues, are an emerging component of many sustainable plant protection attempts. They offer defense in multiple directions, physically strengthening plant tissues and biochemically engaging with the surroundings, and can diminish reliance on chemical pesticides and fertilizers. Physically, phytoliths enhance plant tissue rigidity and toughness, rendering them indigestible and less nutritious to herbivores and pathogens, thereby reducing feeding damage and disease incidence. Biochemically, phytoliths influence plant–microbe and plant–herbivore interactions by decreasing leaf palatability to herbivores, altering rhizosphere microbial communities including silica-specializing, plant-growth-promoting rhizobacteria, and diminishing pathogen proliferation. These effects enhance plant health by reducing pathogen spread and improving overall resilience. Furthermore, phytoliths accomplish crucial biogenic environmental roles such as facilitating biogeochemical silica and participating in essential nutrient cycles that uphold soil pH, fertility, and agricultural sustainability. Their enduring presence in soil enhances its structure, augments water retention, and improves nutrient availability, thereby fostering optimal conditions for plant growth. Additionally, phytoliths play a pivotal role in carbon sequestration and can immobilize heavy metals, mitigating soil contamination and advocating safer agricultural practices. This dual function in bolstering direct plant defense and indirectly enhancing soil health through carbon sequestration underscores the significant potential of phytoliths in sustainable agriculture. In our comprehensive exploration, we delve deeply into the imperative of integrating phytoliths into sustainable agricultural practices to cultivate innovative, eco-friendly, and resilient farming systems. Harnessing the complete potential of phytoliths can lead to advanced strategies for sustainable plant protection, aligning with global initiatives aimed at promoting environmental sustainability and agricultural resilience.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science.
