Isolation, Expression, and Promoter Analysis of GbWRKY2: A Novel Transcription Factor Gene from Ginkgo biloba

Figure 6

Sequence multialignment of the deduced GbWRKY2 protein with other WRKYs. The completely identical amino acids are indicated with white foreground and black background. The conserved amino acids are indicated with white foreground and grey background. Nonsimilar amino acids are indicated with black foreground and white background. The WRKY domain and zinc finger motif (CX₄CX₂₃HX₁H) are underlined. A putative nuclear localization signal (KRRKK) is shown by bold letters and boxed. The GenBank accession numbers of WRKY proteins and translation of their names are shown as follows: GbWRKY2: Ginkgo biloba; CjWRKY1: Coptis japonica var. dissecta BAF41990.1; PsWRKY: Picea sitchensis ADE77055.1; AaWRKY2: Artemisia annua AGR40498.1.
