Eukaryotic Sexual Reproduction Evoked “with a Little Help from My Friends”  James Umen, Ursula Goodenough, Joseph Heitman  Cell  Volume 170, Issue 6, Pages 1059-1061 (September 2017) DOI: 10.1016/j.cell.2017.08.038 Copyright © 2017 Elsevier Inc. Terms and Conditions

Figure 1 Transkingdom Interactions Stimulate a Eukaryotic Sexual Cycle The bacterium V. fischeri secretes an aphrodisiac, EroS, which stimulates swarming and sexual reproduction of the choanoflagellate eukaryotic microbe S. rosetta. Nuclei in the haploid phase (denoted as 1N) prior to mating are colored solid blue and green. The two haploid cells fuse, resulting in a diploid cell (denoted as 2N) after nuclear fusion. Meiosis and recombination then produces haploid progeny carrying a genetic mixture of the parental haploids (denoted as blue and green). (We thank Shelby Priest for her efforts in generating this illustration). Cell 2017 170, 1059-1061DOI: (10.1016/j.cell.2017.08.038) Copyright © 2017 Elsevier Inc. Terms and Conditions
