Analysis of the promoter activity of TaeIF5A1 in transgenic Arabidopsis plants expressing the TaeIF5A1 promoter::GUS construct. A. Schematic map of the T-DNA inserted in the pCAMBIA1301 binary vector, which was used for Arabidopsis transformation. B. The spatial expression of TaeIF5A1 at different growth stages and in different organs or tissues of transgenic Arabidopsis plants expressing the TaeIF5A1 promoter::GUS construct. (a) Three-day-old seedling; (b) One-week-old seedling; (c) Ten-day-old seedling; (d) Two-week-old seedling; (e) Three-week-old seedling; (f) Four-week-old seedling; (g) Five-week-old seedling; (h) Roots from a 5-week-old plant; (i) Two rosette leaves from a 5-week-old plant; (j) The whole flower cluster; (k) Anther in pollen grains; (l) Pistil; (m) The intact pistil; (n) The intact silique; (o) The seed of Arabidopsis.
