Genome architecture drives protein evolution in ciliates.
Studies of microbial eukaryotes have been pivotal in the discovery of biological phenomena, including RNA editing, self-splicing RNA, and telomere addition. Here we extend this list by demonstrating that genome architecture, namely the extensive processing of somatic (macronuclear) genomes in some ciliate lineages, is associated with elevated rates of protein evolution. Using newly developed li...
متن کاملThe Experimental Production of Life Cycles in Ciliates
WOODRUFF and other workers claim on the basis of experiment that a single protozoan can be cultured indefinitely without conjugation. Other observers, chiefly centred around Calkins, claim also with experimental support that unless conjugation takes place the protozoa finally die. A review of this controversy and its historical setting is given in Wilson's The Cell, and nothing is to be gained ...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...

متن کاملUniversal Molecular Computation in Ciliates
How do cells and nature \compute"? They read and \rewrite" DNA all the time, by processes that modify sequences at the DNA or RNA level. In 1994, Adleman's elegant solution to a seven-city Directed Hamiltonian Path problem using DNA 1] launched the new eld of DNA computing, which in a few years has grown to international scope. However, unknown to this eld, ciliated protozoans of genus Oxytrich...
