"I am ready to talk to her as and when she is ready to talk to me," Mukherjee, whose candidature has been opposed by the West Bengal Chief Minister, told reporters here.
Mukherjee said since his candidature for the Presidential poll was announced by the UPA, he had expressed the desire to get the support of all the partners in the ruling alliance.
"I understand they (Trinamool) have not yet taken a decision and that they will take a decision at an appropriate time," said Mukherjee, who is in Kolkata to camapign for the July 19 election.
He said he has been visiting state capitals to thank leaders and members of all the parties who have extended support to him.
Mukherjee said all the UPA partners, except one, have endorsed his candidature and he has also received support from the SP, BSP, RJD, CPI(M), Forward Bloc, JD(U), Shiv Sena and some regional parties.
