More and longer lateral roots presented in Arabidopsis STTM171 transgenic lines. a Sequence alignment of members of miR171 family of Arabidopsis and tomato. The name marked in bold was the miRNA used to construct STTM171. b Schema chart of STTM171 vector construction. c Comparison of the expression of miR171b in STTM171 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 STTM171 transgenic plants compared with the WT plants
