Question

Which of the following statements is inconsistent with your data?

1) When the transcriptional regulator is phosphorylated, it activates transcription of the ethylene-responsive genes.
2) When the transcriptional regulator is not phosphorylated, it binds to DNA.
3) Activation of the protein kinase that binds to the ethylene receptor leads to inactivation of PtpE.
4) Binding of ethylene to its receptor leads to the activation of PtpE.

Answer 1

The inconsistent statement with the data provided is that binding of ethylene to its receptor leads to the activation of PtpE because the information indicates that ethylene pathways activate transcription factors.

Step-by-step explanation:

The statement "Binding of ethylene to its receptor leads to the activation of PtpE" is inconsistent with the data because the provided information suggests phosphorylation events typically result in the activation of transcription factors in ethylene response pathways.

Ethylene binding would likely lead to a phosphorylation cascade, activating transcription factors rather than inactivating proteins like PtpE. Moreover, ethylene-initiated pathways discussed involve the activation of kinases, transcription factors, and ultimately gene expression relevant to plant defense, not their inactivation.

The provided data indicates that the activation of the protein kinase that binds to the ethylene receptor leads to inactivation of PtpE.

Therefore, statement 4, which suggests that the binding of ethylene to its receptor leads to the activation of PtpE, is inconsistent with the data.
