Protein kinase genes essential in <i>S. cerevisiae</i>, <i>S. pombe,</i> or <i>F. graminearum</i>.

aOne of the two paralogs in F. graminearum. -, no distinct ortholog. bOrthologous to nimA, an essential gene in A. nidulans. cIn S. pombe, orb6, nak1, and sid1 are essential genes. KIC1 and CBK1 are essential genes in the wild-type but no ssd1 mutant strains of S. cerevisiae. Fg07344 and Fg05734 are orthologous to Sid1 and Nak1 of S. pombe, respectively. Sid1 has no distinct ortholog in S. cerevisiae. dPHO85, KNS1, IRE1, and VPS15 are not essential genes in S. cerevisiae.
