Kss1 will be preferentially active in a non-mating cell while Fus3 will be preferentially active in a mating cell [2].
The hardy few who try mating cell phones to computers soon bow in homage to the modem jack hiding in the hotel room's desk lamp.
During the period of genomic deletions, a mating cell contains 4 to 8 copies of each chromosome (6).
We created both cdc28-DAmP diploid and tetraploid strains by plasmid shuffling, with one mating cell carrying the WT CDC28 gene on a plasmid.
We then scooped up the mated cell mixture and spread it on minimal yeast nitrogen base (YNB) medium to select diploids.
During mating, cell lysis is observed when the shmoo is forming and Ccw12p is specifically localized to the mating projection, further supporting a local function for cell wall stability during remodelling.
In fission yeast pheromone signalling brings about G1 cell-cycle arrest prior to mating, cell elongation towards the partner cell, and is also involved in cell fusion and karyogamy.
Following syngamy, the nucleus serves as a transport capsule to conjunctly move the whole set of chromosomes of one mating cell into close proximity of the partner nucleus (i.e., nuclear congression) [ 10, 12].
1.5 mL of mating cells with 2 × 105 cells/mL density in 10 mmol/L Tris, pH 7.5 were mixed with 5 μL of partial Schaudin's fixative (two parts saturated HgCl2 to one part 100% ethanol) and incubated for 5 min at room temperature (RT).
Rescues were observed at the frequency of ∼92% of the wells (n = 480 corresponding to 107 mating cells).
