additional information
higher levels of free indole-3-acetic acid (IAA) and abscisic acid (ABA) are identified in germinating seeds of osiaglu mutants compared to wild-type plants. When treated with exogenous IAA and ABA, the osiaglu mutants and wild-type plants show sensitivity to ABA while not IAA, but the exogenous IAA amplified ABA-induced reduction of seed vigour in rice. The continuously higher expressions of ABA-INSENSITIVE 3 (OsABI3) and OsABI5 occur in germinating seeds of osiaglu mutants compared to wild-type plants. ABSCISIC ACID-INSENSITIVE 3 (ABI3) is a major downstream component of ABA signalling, and it has been reported as a major regulator of seed dormancy and ABA inhibition of seed germination
additional information
overexpression of OsIAAGLU reveals a role for indole-3-acetic acid (IAA)-glucose conjugation in modulating rice plant architecture. 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. Transgenic plant phenotypes, overview
