• MiR393 and miR390 synergistically regulate lateral root growth in rice under different conditions.
• Here we show that miR390 induced by auxin promotes lateral root growth in rice
• MiR390 was found to be dominantly expressed at lateral root primordia and roots tips while miR393 mainly expressed in the base part of roots at very low level
• We propose that miR390 induced by auxin triggers the lateral root growth under normal growth conditions, meanwhile miR393 just lurks as a potentially regulative role; Once plants suffer from stresses, miR393 will be induced to negatively regulate miR390-mediated growth of lateral roots in rice
• However, the risen expression level of miR390 induced by auxin didn’t affect the expression of miR393 and its target OsTIR1 (Transport Inhibitor Response 1)

• MiR390, OsTIR1, MiR393 and miR390 synergistically regulate lateral root growth in rice under different conditions., However, the risen expression level of miR390 induced by auxin didn’t affect the expression of miR393 and its target OsTIR1 (Transport Inhibitor Response 1)
• MiR390, OsDRB2~SRL10, DRB2 Modulates Leaf Rolling by Regulating Accumulation of MicroRNAs Related to Leaf Development in Rice., Moreover, OsDRB2 mutation also reduced accumulation of miR160, miR319, miR390, and miR396, which could cause the abnormal leaf development in rl89 by regulating expressions of their target genes related to leaf development
