Abstract

Soil chemical heterogeneity critically alters colonization and diversity of Arbuscular Mycorrhizal Fungi (AMF) in roots of same host plant among different agro-ecological zones. AMF, being a natural soil bio-fertilizer, significantly affects the plant metabolome, changing the quality of its fruit. In present study, subsequent effect of soil chemistry and AMF on nutritional value of tomato fruit from place to place have been monitored. For this purpose, tomato plants along with their rhizospheric soil were sampled from different agro-ecological zones of Pakistan. Soil edaphic factors, AMF root colonization status, rhizospheric spore densities and diversity were estimated and also correlated. Also, the variation in secondary metabolites and antioxidant capacity of tomato fruit was examined. Out results indicated that agro-ecological zones having low soil phosphorus availability exhibits high AMF colonization and diversity, subsequently possessing high phenolic and flavonoid content in tomato fruits resulting in enhanced antioxidant capacity. The concluded correlative effect of spatial AMF diversity and soil chemistry on metabolomic profiles of host plant suggests detailed studies so that qualitative value of various food plants can be enhanced.
