Before revision:  Our results for the crosstalk model suggest that the interaction between transcription factors  exerts more influence on the dynamics of the signalling pathways , and that perturbations in the GA signalling pathway have larger effects on the dynamics of components of the BR signalling pathway , apart from in the case when the model for the BR signalling pathway has periodic solutions .
After revision:  Our results for the crosstalk model suggest that the interaction between transcription factors BZR and DELLA exerts more influence on the dynamics of the signalling pathways , and that perturbations in the GA signalling pathway have larger effects on the dynamics of components of the BR signalling pathway , apart from in the case when the model for the BR signalling pathway has periodic solutions .
