A Genomic PCR for identification of the CsGRF04-VIGS plants. Full-length gels are presented in Supplementary Figure S2. B Expression of CsGRF04 in ten randamly selected positive VIGS lines, as analyzed by qPCR. C Phenotypic observation of WT and CsGRF04-VIGS plants. D, E Length (D) and width (E) statistics of leave from WT and CsGRF04-VIGS plants. The asterisk indicates the significant difference between WT and the CsGRF04-VIGS plants based on a Tukey’s test (*** p < 0.001). The scale bar indicates 1 cmBack to article page
