Symbiotic Rhizobia and their Contribution to Plant Health

Abstract

Silvia Hayat

Symbiotic interactions between plants and rhizobia, a group of nitrogen-fixing bacteria, play a vital role in enhancing plant health and productivity. Rhizobia establish a mutually beneficial relationship with leguminous plants, wherein the bacteria reside within specialized root nodules and convert atmospheric nitrogen into a biologically available form. This process, known as nitrogen fixation, provides an essential nutrient to the plants while promoting soil fertility and sustainability. Beyond nitrogen fixation, rhizobia also contribute to plant health by promoting root development, increasing stress tolerance and influencing nutrient uptake. This article explores the multifaceted contributions of symbiotic rhizobia to plant health, emphasizing the importance of understanding and harnessing these interactions for sustainable agriculture and ecosystem functioning.
