Figure 1 PtrWRKY75 of Populus trichocarpa.
(A) Phylogenetic relationships among PtrWRKY75 and WRKY proteins from other plant species.
(B) Multiple alignment of amino acid sequences of PtrWRKY75 and other plant WRKY proteins.
(C) Subcellular localization of PtrWRKY75 protein in tobacco leaf cells.
(D) Transcript levels of PtrWRKY75 in various organs. Total RNA was isolated from the root, stem, young leaf, mature leaf, and senescent leaf of poplar plants(normalized against internal control UBQ ). Data are means ± SE (n = 6).
(E) Quantitative real-time PCR (qRT-PCR) analysis of PtrWRKY75transcript levels under dehydration stress (normalized against internal control UBQ ). Data are means ± SE (n = 6).
(F) qRT–PCR analysis of PtrWRKY75 transcripts levels in response to exogenous salicylic acid treatment (normalized against internal control UBQ ). Data are means ± SE (n = 6).
