(Top) Schematic representation of Fus1opto used to block cells pre-fusion in the dark and synchronize fusion upon blue light exposure. (Bottom) Time-lapse movie of h90 fus1opto cells mated in the dark and exposed to blue light at t = 0’, where Fus1C-CRY2 is tagged with sfGFP and cytosolic mTagBFP2 is expressed from the P-cell specific map3 promoter.
Nitrogen-starvation of #FissionYeast inactivates growth pathways (incl TORC1) & can trigger sexual reproduction. @sophiemartinlab.bsky.social use proteomic & phosphoproteomic changes during sexual development to show that TORC1 is reactivated by pheromone signaling 🧪 @plosbiology.org plos.io/4h3OUVO

A Petri dish with agar growth medium has fission yeast colonies from tetrads. Tetrad colonies are aligned vertically.
A Petri dish with agar growth medium has patches of fission yeast that are white or pink.
Belated introduction after more than a year on Bluesky 😊
While I post a lot about #Nature, #River, #FlyFishing and #IPA, I use the fission yeast Schizosaccharomyces pombe for my research. At some point, I plan to brew #Beer🍺

An alignment of patches of fission yeast growth on an agar medium on a Petri dish. Some show pink, some are white.
Got some pink yeast 😊
Can we make pink beer if we use this yeast strain ??? 🤔
The ade6 gene mutation causing red pigments for this color change in the fission yeast S. pombe 😉

S. Pombe tetrads from the parental asci are order aligned and have formed colonies on agar growth medium in a petri dish. There are some missing colonies when spores are not viable to grow and proliferate.
#TetradTuesday
Did some tetrad dissection of fission yeast (S. pombe) spores on Friday 😊
Today, they are showing pretty colonies 🥳
Tetrad = four spores produced after yeast meiosis
