Light microscopy and deep-etch electron microscopy were used to visualize triacylglyceride (TAG)-filled lipid bodies (LBs) of the green eukaryotic soil alga Chlamydomonas reinhardtii, a model organism for biodiesel production. Cells growing in nitrogen-replete media contain small cytoplasmic lipid bodies (α-cyto-LBs)

Potassium glutamate accumulates upon hyper-osmotic shock and serves as a temporary osmoprotectant. This salt leads to transcriptional activation of sets of genes that allow the cell to achieve long-term adaptation to high osmolarity. The current experiments show that potassium glutamate
