A comparison of the arbuscular mycorrhizal fungal communities among Bangladeshi modern high yielding and traditional rice varieties

Arbuscular Mycorrhizal Fungi (AMF) are ubiquitous soil microorganisms playing a vital role in the functioning of agricultural ecosystems. Although AMF generally considered to have low host specificity, it has been suggested that modern plant breeding selected crop genotypes more selectively associated with AMF, possibly resulting high yielding varieties (HYV) having lower diversity than traditional varieties. Whether this is true for paddy rice under field conditions not known so far. Here, we aimed at comparing differences communities among HYV and We collected root samples five Bangladeshi (two three HYV) from 40 different fields quantified richness, community composition through throughput amplicon sequencing small subunit (SSU) ribosomal RNA cistron. Overall, 75 OTUs, distributed over six families Glomeraceae as predominant family were found. After accounting conditions, found significantly differed was higher The structure distinct between An indicator species analysis detected 9 OTUs varieties, whereas no HYV. conclude coupled fertilizer application rates provide plausible explanation reduced
