Q.1
Read the following statements regarding arbuscular mycorrhizal fungal (AMF) fatty acids:
(A) . Itcan be used for identification but not for quantification purpose
(B) . Provide useful indication of an infection index for plant root.
(C) . Useful to differentiate AMF and non-AMF.
(D) . 16:1W5 is found in the AMF genus Glomus.
(©). 18:1w11 is found in the genus Gigaspora
Choose the correct answer from the options given below:
- Lipid Biomarkers for Arbuscular Mycorrhizal Fungi (AMF):
- Statement (B) is correct: Phospholipid fatty acid (PLFA) analysis provides an objective quantitative index of AMF root colonization and hyphal biomass in soil ecosystems.
- Statement (C) is correct: Specific signature fatty acids clearly differentiate AMF from saprotrophic fungi, ectomycorrhizal fungi, and bacteria.
- Statement (D) is correct: The fatty acid $16:1\omega5c$ (cis-11-hexadecenoic acid) is the diagnostic signature lipid biomarker characteristic of the AMF genus Glomus and the phylum Glomeromycota.
- Statement (A) is incorrect: PLFA is widely used for both identification and precise biomass quantification.
- Statement (E) is incorrect: The lipid biomarker for Gigaspora is predominantly $20:1\omega9$, not $18:1\omega11$.
- Conclusion: Statements (B), (C), and (D) are correct (Option 3).
