James Umen, Ph.D., associate member at Donald Danforth Plant Science Center, and colleagues have discovered a protein that enables the single-celled green alga Chlamydomonas to count cell divisions, a process that is critically important for its cells to maintain optimal size. The findings were published March 25, in a paper titled, “A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division,” in the open access journal eLife
