For the first time, the effect of 5- and 10-day soil flooding on the ultrastructure of the leaf mesophyll cells of the psammophyte desert madwort (Alyssum desertorum L.) was investigated. The seeds for the experiments were collected from plants of dry sandy areas of the gully slopes of the ravine forest in the steppe zone of the Dnipropetrovsk oblast. It is shown that a characteristic feature of the leaf photosynthetic cells of this species is the presence of single and large, up to 6 pm, peroxisomes, which are in close contact with chloroplasts and mitochondria, playing a key role in photorespiration. The general organization of palisade parenchyma cells on days 5 and 10 of soil flooding is similar to that in the control. A slight decrease in the size of peroxisomes on day 5 of flooding and its increase on day 10 and more often formation of multivesicular structures (assembly of endomembranes) in the vacuole, which is considered as an autophagy enhancement of the cytoplasm under hypoxia, were noted. Differences in the ultrastructure of chloroplasts under the influence of soil flooding consisted in a significant, almost twofold increase in transient starch, the size and number of plastoglobules, especially on day 10, and swelling of granal and stroma thylakoids on day 10. Changes in the ultrastructure of desert madwort chloroplasts under the influence of soil flooding coincide with those of mesophytes studied in this respect. The obtained data on the chloroplast ultrastructure of desert madwort psammophyte prove the functioning of the photosynthetic apparatus in conditions of short-term soil flooding, which contributes to the survival of seedlings. The subsequent yellowing of leaves and death of plants indicates, as is assumed, the lack of systemic adaptation, primarily metabolic, that is, the transition to anaerobic metabolism, in this species to long-term hypoxia.

Researchers reveal how a #nanomachine cleans up inside the #cell.
Have you ever put off cleaning the house or decluttering the overflowing basement? Living cells cannot afford this procrastination when it comes to clearing the decks. Tiny garbage chutes are constantly active there to capture worn-out proteins, faulty cell components, or defective organelles. These garbage chutes, called autophagosomes, pick out the discarded components before they accumulate in the cell and cause damage. The cellular waste is then passed on to the cell's own recycling machinery, the lysosome, where it is digested and recycled.
New #laser technology for #micromanipulation allows researchers to control movement in living #cells
https://phys.org/news/2023-05-laser-technology-micromanipulation-movement-cells.html
A new laser technology called FLUCS (Focused Light-induced Cytoplasmic Streaming) makes it possible to influence and specifically control movements within living cells and embryos. The technology developed at the Max Planck Institute of Molecular Cell Biology and Genetics has now been licensed by Rapp OptoElectronic and can help us to better understand embryonic developmental disorders. As an additional module for high-resolution microscopes, FLUCS will not only improve cell biological and medical research in the future, but also open up new possibilities in microfluidics.
