CaCML13 Acts Positively in Pepper Immunity Against Ralstonia solanacearum Infection Forming Feedback Loop with CabZIP63.

ABSTRACT: Ca2+-signaling-which requires the presence of calcium sensors such as calmodulin (CaM) and calmodulin-like (CML) proteins-is crucial for the regulation of plant immunity against pathogen attack. However, the underlying mechanisms remain elusive, especially the roles of CMLs involved in plant immunity remains largely uninvestigated. In the present study, CaCML13, a calmodulin-like protein of pepper that was originally found to be upregulated by Ralstonia solanacearum inoculation (RSI) in RNA-seq, was functionally characterized in immunity against RSI. CaCML13 was found to target the whole epidermal cell including plasma membrane, cytoplasm and nucleus. We also confirmed that CaCML13 was upregulated by RSI in pepper roots by quantitative real-time PCR (qRT-PCR). The silencing of CaCML13 sign
