Downstream of a Kinase Cascade: A Trihelix Transcription Factor Represses Immune Genes

Immunity in plants relies in large part on signaling mediated by protein kinase cascades (reviewed in [Tena et al., 2011][1]). Cascades that lead to pattern-triggered immunity are initiated by the recognition of microbe-associated molecular patterns (MAMPs), such as flg22, by receptors such as
