title: PB2PrS4_DNA_seq of Panicum racemosum
design: Arbuscular mycorrhizal fungal communities colonizing roots of plants occurring on the Brazilian coast were analyzed through DNA metabarcoding approach using the nuclear small subunit (SSU) rRNA gene. Roots were ground in liquid nitrogen with a mortar and pestle and DNA was extracted from 80 mg of dried roots with PowerSoil 96 Well Soil DNA Isolation Kit (MO BIO Laboratories, Carlsbad, CA, USA) according to the manufacturers specifications.
