In Arabidopsis thaliana, miR396family contains two members:miR396a and miR396b, which are encoded by MIR396a and MIR396b, respectively. miR396targets seven members of GRF (Growth-Regulating Factor) family and a basic Helix-Loop-Helix transcription factor bHLH74. Previous studies revealed that miR396-target regulates cell proliferation and plays a critical role in leaf development.
In order to explore the function of different members of MIR396in root development, we studied the expression patterns of At...
