Activities of PtAP66 and PtAP17 promoters in transgenic Arabidopsis. GUS staining was detected in PtAP66promoter::GUS (a-i) and PtAP17promoter::GUS (j-r) transgenic plants. (a-c, j-l) 5-day-old seedlings, their roots and root tips, respectively. (d, m) Aerial parts of 2-week-old seedlings. (e-h, n-q) Inflorescences, siliques, rosette leaves and stem cross-sections of 40-day-old plants, respectively. (i, r) Magnification of stem cross-sections. if, interfascicular fiber; mx, metaxylem. Scale bars indicate 500 μm in a, d-g, j and m-p and 100 μm bars for b, c, h, i, k, l, q and r
