The expression pattern of OsIAGT1. a Expression pattern of OsIAGT1 in rice. Young leaf and root were harvested from two-week-old seedlings. Adult leaf and stem were from plants growing for 2 months. Old leaf, root and stem were from plants growing for three and a half months. The dough grain was from maturing seeds. Transcript levels were normalized relatively to the mRNA levels of OsActin1. c and d Induction of OsIAGT1 transcription by IAA or IBA. One-week-old wild-type rice was subjected to treatment with or without 10 μM IBA or 10 μM IAA for 1, 3, 6 and 12 h, respectively. Expression of OsIAGT1 was analyzed with qRT-PCR analysis. The results represent mean ± SD from three replicates. Different lower-case letters indicate significant difference based on the Duncan’s multiple range test (p < 0.05)
