NOTORHIZAL Meaning and Definition

1. The term "notorhizal" refers to a specific type of root system that is formed in some plants. It is derived from the combination of two words, "noto" meaning back or reverse, and "rhizal" which refers to roots. In botanical terms, it describes a root system where the primary or tap root grows in a reverse or backward direction.

   This type of root system is commonly found in certain plant families, such as the Fabaceae (legume) family. In notorhizal plants, the primary root, which is initially formed during the seedling stage, starts growing downwards before it begins to curve or reorient itself and grow horizontally along or just below the surface of the ground. As a result, the primary root appears to be growing in the opposite direction, relative to the typical downward growth observed in plants with a tap root system.

   The main function of notorhizal roots is to enable the plant to efficiently gather nutrients and water from the soil. By growing horizontally and spreading widely, notorhizal roots can explore a larger area of soil and access resources present at various depths. Moreover, notorhizal root systems are known for their ability to form symbiotic associations with certain soil bacteria, particularly nitrogen-fixing bacteria called rhizobia. These bacteria colonize the roots and form specialized structures called nodules, where they convert atmospheric nitrogen into a form that can be used by the plant as a nutrient. This unique adaptation makes notorhizal plants crucial in nitrogen cycling and contributes to soil fertility.
