Transcriptional induction of AtTPPD by salt stress. AtTPPD and AtTPPE expression in roots (A) and shoots (B) of plants under control and salt stress conditions was analyzed by qRT-PCR. Ten-day-old seedlings were transferred to plates without (control) or with supplementation of 200 mM NaCl. Expression was normalized to PP2A and Ubi1 and is represented as fold change of expression relative to the respective controls. Data are mean±SD of three independent experiments. qRT-PCR, real-time polymerase chain reaction.
