Incipient cytorrhysis
Cytorrhysis is the permanent and irreparable damage to the cell wall after the complete collapse of a plant cell due to the loss of internal positive pressure (hydraulic turgor pressure). Positive pressure within a plant cell is required to maintain the upright structure of the cell wall. Desiccation … See more Desiccation tolerance refers to the ability of a cell to successfully rehydrate without irreparable damage to the cell wall following severe dehydration. Avoiding cellular damage due to metabolic, mechanical, and See more Many resurrection plants use constitutive and inducible mechanisms to deal with drought and then later desiccation stress. Protective proteins such as cyclophilins, dehydrins, and LEA proteins are maintained at levels within a desiccation resistant species typically … See more WebTherefore, cytorrhysis assays were subsequently performed using polyethylene glycerol 8000 (PEG8000), which has a larger molecular size than glycerol, as the external inductive …

WebNov 16, 2024 · An incipient cytorrhysis assay was carried out by allowing appressoria to form in water on borosilicate cover slips for 24 hr, after which the water was replaced with a range of aqueous glycerol ranging from 0.25 to 2.5M and, after 30 min, the frequency of cytorrhysis determined ( de Jong et al. 1997 ). WebSep 9, 2024 · Appressorium turgor pressure was evaluated through incipient cytorrhysis (cell collapse) assays as described previously ( Howard et al., 1991 ). At 24–48 hpi, appressoria were incubated in a series of glycerol solutions (0.5–2.0 M) for 5 min and then the collapsed appressoria were counted under a microscope.
