Senescence and the Fluidity of Rose Petal Membranes : RELATIONSHIP TO PHOSPHOLIPID METABOLISM.
In previous work, senescence of rose petal cells has been shown to be accompanied by a gradual decrease of membrane fluidity, as measured by a fluorescence polarization technique. Concomitantly, an increase in the free sterol-to-phospholipid ratio was found. Both observations were verified in this study. Further, experiments carried out on whole tissue and isolated protoplasts during senescence...
متن کاملPhysiology and molecular biology of petal senescence.
Petal senescence is reviewed, with the main emphasis on gene expression in relation to physiological functions. Autophagy seems to be the major mechanism for large-scale degradation of macromolecules, but it is still unclear if it contributes to cell death. Depending on the species, petal senescence is controlled by ethylene or is independent of this hormone. EIN3-like (EIL) transcription facto...
متن کاملChanges in the Physical State of Membrane Lipids during Senescence of Rose Petals.
Changes in the physical state of microsomal membrane lipids during senescence of rose flower petals (Rosa hyb. L. cv Mercedes) were measured by x-ray diffraction analysis. During senescence of cut flowers held at 22 degrees C, lipid in the ordered, gel phase appeared in the otherwise disordered, liquid-crystalline phase lipids of the membranes. This was due to an increase in the phase transitio...
متن کاملIs petal senescence due to sugar starvation?
Senescence occurs at every stage of plant development. Shriveling of the cotyledons in young plants and the seasonal recurrence of leaf yellowing are obvious examples. Similarly, after pollination, petals have fulfilled their biological role and become senescent. Despite this ubiquity, however, the molecular events that initiate senescence have thus far remained a mystery. Thimann et al. (1977)...
متن کاملThe rose petal effect and the modes of superhydrophobicity.
The wetting of rough surfaces remains a subject of active investigation by scientists. The contact angle (CA) is a traditional parameter used to characterize the hydrophobicity/philicity of a solid surface. However, it was found recently that high CAs can coexist with strong adhesion between water and a solid surface in the case of the so-called 'rose petal effect'. Several additional parameter...
