Protein Variants Comment Organism
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 Oryza sativa Japonica Group

General Information

General Information Comment Organism
malfunction disruption of OsIAGLU results in low seed vigour in rice, ABA-sensitive phenotypes during seed germination, overview Oryza sativa Japonica Group
physiological function the enzyme plays a role on seed vigour in seeds. Transcriptome analysis reveals that the indole-3-acetic acid (IAA)- and abscisic acid (ABA)-related genes are involved in the OsIAGLU regulation of seed vigour in rice. The regulation of seed vigour by OsIAGLU accurs through modulating IAA and ABA levels to alert OsABIs expression in germinating seeds in rice. Based on analysis of single-nucleotide polymorphism data of rice accessions, two haplotypes of OsIAGLU that positively correlate with seed vigour are identified in Oryza sativa subsp. indica accessions.
