• MicroRNA (miRNA)-mediated regulation of auxin signaling components plays a critical role in plant development. miRNA expression and functional diversity contribute to the complexity of regulatory networks of miRNA/target modules. • This study functionally characterizes two members of the rice (Oryza sativa) miR393 family and their target genes, OsTIR1 and(More)
Hydrogen peroxide (H(2)O(2)) is known to be a key player in apoptosis in animals. The components and pathways regulating H(2)O(2)-induced programmed cell death in plants, however, remain largely unknown. In the present study, rice transgenic lines overexpressing Bcl-2, a human apoptotic suppressor, were obtained. These transgenic lines showed increased(More)
The conserved miRNA393 family is thought to be involved in root elongation, leaf development and stress responses, but its role during seed germination and seedling establishment remains unclear. In this study, expression of the MIR393a/target module and its role in germinating rice (Oryza sativa L.) seeds were investigated. β-Glucuronidase (GUS) analysis(More)
