Abstract
The WRKY web, which is comprised of a subset of WRKY transcription factors (TFs), plays a crucial role in the regulation of plant immunity, however, the mode of organization and operation of this network remains obscure, especially in non-model plants such as pepper (Capsicum annuum). Herein, CaWRKY22, a member of a subgroup of IIe WRKY proteins from pepper, was functionally characterized in pepper immunity against Ralstonia Solanacearum. CaWRKY22 was found to target the nuclei, and its transcript level was significantly upregulated by Ralstonia Solanacearum inoculation (RSI) and exogenously applied salicylic acid (SA), Methyl jasmonate (MeJA), or ethephon (ETH)...
