The Role of Fungi in Plant Development and Symbiosis

Fungi play an essential role in plant development and ecological balance contributing to nutrient cycling growth promotion and resilience to environmental stress. This manuscript examines the complex interactions between fungi and plants focusing on mutualistic relationships that facilitate nutrient absorption enhance plant growth and provide disease resistance. Mycorrhizal associations especially arbuscular mycorrhizae and ectomycorrhizae illustrate the mutual benefits plants receive through nutrient exchange and improved soil health (Smith & Read 2008). Endophytic fungi further contribute to plant survival by inhabiting internal tissues enhancing stress tolerance and protecting against pathogens (Arnold 2007). Fungi also produce growth-promoting hormones like auxins aiding plant development under adverse conditions (Harman 2006).Pathogenic fungi present challenges as they invade plants disrupting cellular processes and affecting agricultural productivity (Agrios 2005). However advancements in fungal research have opened new avenues in sustainable agriculture where mycorrhizal fungi are used as bioinoculants improving crop yield and soil remediation.
