sample commentGeneral description. Rice plants (Oryza sativa L. cultivar gNipponbareh) were cultivated in paddy fields dressed with low N (LN; 0 kg ha-1) and standard N (SN; 30 kg ha-1). The roots (approximately 100 g) were sampled on August 26, 2009 and homogenized without surface sterilization to prepare the root-associated bacterial cells, and the bacterial cells were extracted and purified using a bacterial cell enrichment method. Total DNA was extracted from the cell fraction.
