Which of the following fungi form endomycorrhizal associations with the plants?
निम्नलिखित में से कौन से कवक पौधों के साथ एंडोमाइकोराइज़ल (अंतःकवकजाल / Endomycorrhizal) संबंध बनाते हैं?

Endomycorrhizal Fungi:

  • Arbuscular mycorrhizae (AM) / Vesicular-Arbuscular Mycorrhizae (VAM) represent the most widespread type of endomycorrhiza, forming mutualistic symbiotic associations with more than 80% of terrestrial vascular plants.
  • The hyphae penetrate root cortical cells to form branched arbuscules (for nutrient exchange, notably phosphorus) and vesicles (for storage).
  • All arbuscular mycorrhizal fungi belong exclusively to the phylum Glomeromycota (Glomeromycetes), including genera such as Glomus, Gigaspora, Acaulospora, and Rhizophagus.
  • Ectomycorrhizae are predominantly formed by Basidiomycetes and Ascomycetes with forest trees.

Correct Answer: Option 4 (Glomeromycetes).
