CAA84882.1

The Skt5p homolog in Schizosaccharomyces pombe (27.586 % identity, 2.93e−14 E-value) is a regulatory gene that is involved in septum formation in fungi (Matsuo et al. 2004) and is required for chitin synthesis during mating in Saccharomyces cerevisiae [61].

Cmk1p

CMK1/S. cerevisiae

47%/1e−17/31.96%

Recip: 44%/1e−17/31.96%

KZV11616.1

In S. cerevisiae, exposure to pheromones induces sexual differentiation, but also induces cell death (Severin and Hyman 2002). CMK1 encodes a Ca2+/calmodulin-dependent protein kinase (Pausch et al. 1991) which is involved in the cell survival to pheromones [63].

40%/4e−20/25.48%

Recip: 56%/4e−20/25.48%

KZV12764.1

In S. cerevisiae, SPS1 is transcribed at the end of meiosis and plays a role in the spore wall development [64].

MKK2/S. cerevisiae

30%/1e−19/30.92%

Recip: 30%/2e−19/30.92%

KZV07375.1

MKK2 is involved in the cell wall integrity MAPK kinases cascade, which is associated to the

pheromone response during mating in budding yeast [32].

87%/6e−32/24.56%

Recip: 90%/6e−32/24.56%

KZV11281.1

MUP1 is a methionine transporter. In U. maydis methionine auxotrophs lack the ability to from mating tubes, but this defect is restored with the addition of methionine [65].

97%/3e−30/26.02%

Recip: 95%/5e−30/25.61%

KZV12646.1
