Dear all. This is devastating news. Marty was one of the greatest molecular biologists to take advantage of Tetrahymena to answer fundamental scientific questions. While I did not have the privilege of being directly mentored by him, I always benefited from his critical comments. The Tetrahymena Genome Project would not have been gotten off the ground without his essential contributions. My condolences to his family and to the Ciliate community. Eduardo Orias
