Endoplasmic reticulum (ER) whorl and whorl-like structure in desiccating cell. a Wild type cells growing in YPD medium for 3 days to stationary phase, then dried for 14 days, showing the endoplasmic reticulum (ER) whorl structure; b A whorl-like ER structure in cells at the same growing conditions as in (A). c ire1Δ mutant growing in YPD medium for 3 days to stationary phase, then dried for 14 days, showing the disorganized ER membrane around the nucleus, and the opening of the nucleus (arrow). d hac1Δ mutant growing in YPD medium for 3 days to stationary phase, then dried for 14 days, showing the opening of the nucleus (arrow).
