Method Abstract: "[Researchers] used soft X-ray tomography (SXT)-a high-resolution, quantitative imaging technique-to measure cell size and organelle volumes in yeasts"
Comments P.233 right column bottom paragraph to p.234 left column top paragraph: "This work demonstrates that both haploid and diploid cells of S. cerevisiae maintain a constant ratio of total major organelle volume to cell volume throughout the cell cycle. To find out whether this correlation was influenced by morphology, species or mutation, [researchers] characterized C. albicans, Sz. pombe and a S. cerevisiae mutant. Surprisingly, similar O: C ratios (i.e. 0.18–0.21) were observed in C. albicans that exhibited three different phenotypes (i.e. yeast-like, germ tubes and hyphae), Sz. pombe cells at the different stages of cell cycle, and cofilin mutant cells (coff1-22) (data not shown). The ratio of nuclear to cell volume was also similar among all of these different yeasts (i.e. 0.05–0.08)."
