Definition of mycorrhiza in English:

noun (plural mycorrhizae ˌmʌɪkə(ʊ)ˈrʌɪziː)

A fungus which grows in association with the roots of a plant in a symbiotic or mildly pathogenic relationship.
Example sentences
  • In addition, most vascular plants could not grow without the symbiotic fungi, or mycorrhizae, that inhabit their roots and supply essential nutrients.
  • A special type of beneficial root fungi, called mycorrhizae, actually grow into plant roots, feeding off plant sap but also providing water and nutrients to the plant.
  • These data thus support the authors' suggestion that mycorrhizae are important in enabling plant roots to exploit nutrient patches that might otherwise be out of reach.


Example sentences
  • One hundred intersections were investigated out of a subsample of root pieces of one plant and the presence of at least one mycorrhizal hypha was counted as infection.
  • We quantified mycorrhizal colonization rates because mycorrhizae can play an important role in the nitrogen nutrition of plants.
  • Roots were stained, mycorrhizal colonization in roots was measured and fungal hyphae development in soil was determined as explained above.


Late 19th century: modern Latin, from myco- 'of fungi' + Greek rhiza 'root'.
