This I4-FFL ensures robust and tunable accumulation of salicylic acid during immune activation through flagellin sensing. Jasmonate (JA) induces EDS5 expression while repressing the positive EDS5 regulator …

WebIncoherent feed-forward loops have been characterized in the context of transcriptional networks, where the inhibitors are transcription factors or RNA binding proteins that directly repress expression of another primary target, giving rise to a biphasic response (40, 41). There are four varieties of incoherent feedforward (FF) control in a three-node system [5, 23]. In this paper, we study the incoherent feedforward loop Type 1 (I1-FFL) motif, in which the input signal (X) activates both the intermediate (Y) and the ultimate output (Z), while Y represses Z (Fig. 1a) [12]. Our model is one of … See more Previous analysis of the above model (Eqs. 1–3) showed that I1-FFL transcriptional regulation can, under the right conditions, act as a fold-change detector (FCD) [12].
