Construction of iaaglu mutants using the CRISPR/Cas9 system. Construction of hybrids Dongjin as well as IAAGLUOE3 containing pDR5:GUS obtained by crossing pDR5:GUS plants as the male parent with wild-type, OsIAAGLU overexpression plants (IAAGLUOE3) as the female parent, respectively. OsIAAGLU-overexpressing plants are insensitive to exogenous IAA/NAA (1-naphthalene acetic acid) and exhibit reduced root gravitropism.

Expression

|---|---|---|
| Oryza sativa Japonica Group | expression of OsIAAGLU can be induced by indole-3-acetic acid (IAA) and 1-naphthalene acetic acid (NAA). Quantitative RT-PCR analysis show that within 2-6 h of exogenous auxin (0.01 mM IAA or 0.001 mM NAA) treatment, the expression of OsIAAGLU is upregulated in the leaves of 14-day-old rice seedlings. The response to NAA is earlier and many times greater than IAA. The transgenic plants are shorter than the wild-type plants and exhibit exaggerated leaf angles at the 5-leaf stage compared to the wild-type plants | up |
General Information
| General Information | Comment | Organism |
|---|---|---|
| malfunction | Overexpression of OsIAAGLU results in altered plant architecture. The number of tillers and leaf angle is significantly increased with a concomitant decrease in plant height and panicle length in the transgenic rice lines overexpressing OsIAAGLU compared to the wild-type plants. Phenotypes of iaaglu mutants show no obvious differences with wild-type plants. Overexpression of OsIAAGLU results in reduced sensitivity to indole-3-acetic acid (IAA) and 1-naphthalene acetic acid (NAA) and altered gravitropic response of the roots in the transgenic plants. Free IAA contents in the leaves, root tips, and lamina joint of OsIAAGLU-overexpressing transgenic lines are lower than those of wild-type plants. The transgenic plants are shorter than the wild-type plants and exhibit exaggerated leaf angles at the 5-leaf stage compared to the wild-type plants | Oryza sativa Japonica Group |
| physiological function | indole-3-acetic acid glucosyltransferase (OsIAAGLU) catalyzes the reaction of free indole-3-acetic acid (IAA) with glucose to generate IAA-glucose. OsIAAGLU plays a regulatory role in IAA homeostasis and rice architecture | Oryza sativa Japonica Group |
