摘要

Arbuscular mycorrhiza, a widespread symbiotic association between higher plant roots and Glomeromycota fungi, is important for plant nutrition, particularly phosphorus uptake. The establishment of this partnership initiates with intricate molecular crosstalk. Plants, especially under nutrient stress, exude strigolactones into the rhizosphere. These signalling molecules attract endomycorrhizal fungi, stimulate spore germination, promote hyphal branching, and activate fungal metabolic pathways preparing for root colonization. Upon root contact, arbuscular mycorrhizal fungi release Myc (mycorrhizal) factors, such as chitooligosaccharides (COs) and lipo-chitooligosaccharides (LCOs). These fungal signals are recognized by plant receptors, triggering the activation of the Common Symbiosis Pathway (CSP) within the root. This pathway orchestrates the necessary cellular and genetic changes for fungal entry and arbuscule formation, the site of nutrient exchange for both the partners. This molecular dialogue continues for the maintenance of the symbiosis, involving the regulated transfer of carbon from the plant to the fungus and mineral nutrients vice versa, alongside the dynamic turnover of arbuscules. Beyond nutrient acquisition, arbuscular mycorrhizal fungi play crucial roles in bioremediation by enhancing plant resilience and uptake of heavy metals and organic pollutants, and in ecological succession by facilitating the establishment of pioneer plant species in harsh environments and influencing plant community development across different seral stages. These attributes might have made arbuscular mycorrhiza as one of the major protagonists in primary terrestrial colonization of primeval photosynthesizing plants on primitive earth, making them important for evolutionary studies. Understanding this molecular interplay is as well vital for leveraging the potential of arbuscular mycorrhiza in sustainable agriculture, environmental restoration efforts and other biotechnological applications.
