Root development refers to the process by which plant roots grow and develop in order to absorb water and nutrients from the soil. This process involves the formation of various root structures, such as primary and lateral roots, as well as interactions with soil microorganisms. Researchers in this area study the molecular, genetic, and physiological mechanisms that regulate root growth and development, as well as how environmental factors, such as water availability and soil composition, influence root development. Understanding root development is important for improving crop productivity, nutrient uptake, and overall plant health.
