Upon his arrival at Stanford, he began a collaboration with Edward Tatum, who had been working with Neurospora crassa since 1941 in collaboration with George Beadle. In this way, he was connected to the very earliest research with Neurospora. Throughout his career, he continued to work with Neurospora crassa, which he often championed as a model organism. Many of his most important papers were concerned with the genetic basis of meiosis and ascospore genesis. Tatum won the Nobel Prize for his work in genetics Edward Lawrie Tatum (December 14, 1909 - November 5, 1975) was an American geneticist. ... Binomial name Neurospora crassa Shear & B.O.
