Abstract

Figure 1

Identification of IAA27 related to root development in the parents ‘BC’ and ‘M9’ and their progenies. (A) Variation in the IAA27 CDS sequence of the parents ‘BC’ and ‘M9’. (B) Amino acid sequence analysis of IAA27 transcription factors. (C) Phenotypes of adventitious roots from six progenies crossed from ‘BC’ and ‘M9’. The progenies were harvested for adventitious root trait analysis at 30 days after cutting. Scale bars: 5 cm. (D) After low phosphorus treatment for 30 days, adventitious roots of progenies were photographed. Scale bars: 5 cm.

MdARFs directly bind to the promoter of MdSAUR76 and MdLBD16. (A) Results of the Y1H, showing MdARF8, MdARF26, and MdARF27 binding to the MdSAUR76 and MdLBD16 promoter. (B–E) Effect of MdARFs on the regulation of the MdSAUR76 and MdLBD16 promoter in tobacco leaves and LUC/REN ratio analysis. Red color represents a stronger signal, and violet color represents a weaker signal. Error bars indicate standard deviations (s.d.) from three biological replicates. These assays were repeated three times with the same results. Different letters represent significant differences (p < 0.05).

Interaction of MdIAA27 with the promoter of MdSAUR76. (A) Schematic diagram of the MdSAUR76 promoter region; (B) Y1H confirmation of the binding of MdSAUR76 promoter P2 and P3 fragments by MdARF27; (C) EMSA assay showing that MdARF27 could directly bind to the promoters of MdSAUR76 (P2 and P3). The plus and minus signs indicate the presence or absence of that protein, respectively.
