Arabidopsis thaliana | auxin is a strong negative regulator of AtAOX1 a transcript abundance | down |
Arabidopsis thaliana | the transcription factor MYB29 acts as a negative regulator, not directly by binding the AtAOX1a promoter, but rather by crosstalk with a number of hormone signalling pathways that interact with ETHYLENE RESPONSE FACTOR and WRKY transcription factors | down |
Arabidopsis thaliana | WRKY transcription factors 15 and 40 act as negative regulators of AtAOX1a. It is possible that they and other negative regulators are displaced when the latent NAC17 transcription factor is released from the ER upon proteolysis, with subsequent competition for the binding site | down |
Arabidopsis thaliana | cyclin-dependent kinase E1 (CDKE1), a subunit of the mediator complex, is required for induction of AOX1a in Arabidopsis,acting at both a transcriptional and post-transcriptional level | up |
Arabidopsis thaliana | the transcription of AtAOX1a is under strong negative regulation and can be derepressed by activation of the NAC17 transcription factor present in the ER. A variety of ER-bound NAC transcription factors, including NAC13, act downstream of NAC17 to positively regulate AtAOX1a expression. NAC17 is a tail-anchored protein in the ER that must be released by proteolytic cleavage to turn on the expression of AtAOX1a itself and other downstream regulators of AtAOX1a. The transcript abundance of NAC17 is low and not affected by a wide variety of stresses that induce AtAOX1a, and other membrane-bound NAC transcription factors cannot compensate for it. It appears that this positive masterregulator of AOX1a is constitutively expressed at a low level in a latent form and is activated (by proteolytic cleavage on the ER) by mitochondrial dysfunction to turn on AtAOX1a. AtAOX1a is under both negative and positive regulation by WRKY transcription factors that bind to the AtAOX1a promoter | up |
Neurospora crassa | two transcription factors, AOD2 and AOD5, are required for the expression of AOX when the cytochrome pathway is inhibited | up |
