FIGURE 4.
Putative cis-elements in the promoter regions of PbCIPK genes. Stress-responsive cis-elements ABRE (involved in the abscisic acid responsiveness), CE3 (involved in ABA and VP1 responsiveness), HSE (involved in heat and oxidative stress responsiveness), LTR (involved in the low-temperature responsiveness), MBR (MYB binding site involved in ABA and drought responsiveness), W-box (WRKY binding site involved in abiotic stress and defense response) and WUN-motif (involved in the wound responsiveness) were shown in the promoters regions (1000 bp upstream) of PbCIPKs.
