Seminal root length in the wild type (WT, Dongjin) and ospin1b mutants. Seedlings were grown in hydroponic medium containing normal nutrition (control; 2.5 mM N, 300 μM ), low N, or low P (LN, 0.02 mM; LP, 2 µM P), or subjected to treatment with sodium nitroprusside (SNP, 10 µM) or GR24 (analog of SLs, 2.5 µM) for 14 days. (a), Morphology and (b,c) seminal root lengths of rice plants. Data are means ± SE of eight replicates (b,c) and bars with different letters indicate significant differences at p < 0.05, as determined by ANOVA followed by the LSD test.
