Multidimensional scaling plots generated from ARISA profiles with primers ITSF and ITSReub for rice (A) shoot- and (B) root-associated bacterial communities under low (LN), standard (SN), and high (HN) nitrogen conditions. Nine cultivars of O. sativa and seven lines of other Oryza species were used for shoot-associated bacterial community analysis with three replications, and five cultivars of O. sativa were used for root-associated bacterial community analysis with at least two replications (Table 1).
