Fig. 4From: Rice nitrate transporter OsNPF7.2 positively regulates tiller number and grain yieldOsNPF7.2 influenced NO3− influx, NO3− concentration and total nitrogen content among transgenic lines. a Analysis of NO3− influx rate among WT, OX lines, Ri lines and osnpf7.2 cultured under 6 mM NaNO3 supply. b NO3− concentration of WT, OX lines, Ri lines and osnpf7.2 cultured under 6 mM NaNO3 supply. c Comparison of total nitrogen content among WT, OX lines, Ri lines and osnpf7.2 cultured under 6 mM NaNO3 supply. d Expression level of crucial genes involved in absorbing, transporting and assimilation of nitrate among WT, OX-M, Ri-M and osnpf7.2 cultured under 6 mM NaNO3 supply. OX-M and Ri-M indicated that mixed equal-amount RNA which extracted from 10 seedlings’ tiller buds of each three OX lines and Ri lines, respectively. Date are shown as mean ± SD (n = 10) from three replicates; “*”, “**” and “***” indicated significant differences at P < 0.05, P < 0.01 and P < 0.001, respectivelyBack to article page
