Figure 1

The seminal root length and histochemical localization of pDR5::GUS expression in the root tip of wild-type (WT) rice seedlings (Shiokari). Seedlings were grown in hydroponic medium containing normal nutrition (control; 2.5 mM N, 300 μM P), low N, or low P (LN, 0.02 mM; LP, 2 µM), or subjected to treatment with sodium nitroprusside (SNP, 10 µM), 2-(4-carboxyphenyl)-4,4,5,5- tetramethylimidazoline-1-oxyl-3-oxide (cPTIO, 80 µM), or a-naphthylacetic acid (NAA, 10 nM), or localized application of N-1-naphthylphthalamic acid (NPA, 20 µM) by dispensing diluted agar onto the root-shoot junction for 14 days. (a) Seminal root length; (b) histochemical localization of pDR5::GUS expression in root tip. Bar = 1 mm. Data are means ± SE of eight replicates and bars with different letters indicate significant differences at p < 0.05, as determined by ANOVA followed by the LSD test.
