Communications Minister Eamon Ryan tonight said he hoped Green Party ministers would not be affected by a Cabinet reshuffle by Taoiseach-in-waiting Brian Cowen next month.
The Fianna Fail leader-designate is expected to assign new Government portfolios when he succeeds Bertie Ahern on May 7.
Mr Ryan said he didn't think the change of leadership would affect the working relationship between the Coalition partners.
"I would be hopeful we would stay in our ministries," he said, referring to himself, Environment Minister John Gormley and Horticulture Minister Trevor Sargent.
Mr Ryan and Mr Cowen were on opposition sides of the programme for government talks tabled before the Greens entered power with Fianna Fail last June.
"I can work with Brian Cowen as Taoiseach," Mr Ryan added.
The TD said the Greens had made genuine progress on several core issues in the ten months it had been in Government.
Speaking ahead of the Green Party Convention in Dundalk this weekend, the TD denied that there was significant disagreement within the party on the Lisbon Treaty.
Party members at a special convention in January voted to support the charter but it was less than the 2:1 majority required.
But Mr Ryan said: "The Greens are a European party. We are not Eurosceptics."
The theme of the three-day Convention is Vision Into Action and party leader Mr Gormley is expected to focus on climate change in his keynote address on Saturday night.
Up to 600 delegates will also discuss issues including cycle paths, carbon footprints and ways to attract Polish voters.
