More and longer lateral roots presented in Arabidopsis STTM390 transgenic lines. a Sequence alignment of members of miR390 family of Arabidopsis and tomato. The name marked in bold was the miRNA used to construct STTM vector. b Schema chart of STTM390 vector construction. c Comparison of the expression of miR390b-5p in STTM390 transgenic plant and wild type (WT). Asterisks indicate statistically significant differences compared with WT plants by Student’s t test (*P < 0.05; **P < 0.01). d The phenotypes of two weeks old seedling of representative STTM390 transgenic plants compared with the WT plants
