Yeast Made to Harvest Light Hint at Evolution’s Past Scientists transferred light-harvesting proteins into yeast for the first time, shining a light on the past lives of eukaryotic cells.

Now we have the tools to do that,” he explains, referencing the Calico Labs team’s development of a molecule whose fluorescence level corresponds to the acidity of the yeast vacuole.

Leveille grew yeast at their typical laboratory temperature of 86 F with plenty of food. After the food dwindled, the yeast cell vacuole membranes underwent phase separation, as expected.

While it usually needs darkness to thrive, scientists have created a light-powered yeast by moving a single gene.

The researchers found the acidity of a structure in yeast cells known as the vacuole is critical to aging and the functioning of mitochondria -- the power plants of the cell.

But the vacuole of baker's yeast, a widely-studied organism, has a membrane large enough to observe the structural details of each step in the fusion process.

A) A 3D reconstruction of a yeast cell engulfing cytoplasmic misfolded proteins (purple) inside of the degradation cellular machinery, or vacuole (gray). B) Super-resolution reconstructions ...
