20.500.12556/DiRROS-23937 Chloroplast redox state changes indicate cell-to-cell signalling during the hypersensitive response version v3 We performed detailed spatiotemporal analysis of chloroplast redox response to potato virus Y (PVY) infection in resistant Ny‐1-gene-bearing potato and its transgenic counterpart with impaired SA accumulation and compromised resistance. We found that the chloroplasts are highly oxidized in the cells adjacent to the cell death zone at different stages after virus inoculation in both genotypes. This hypothesis is further supported by highly induced formation of stroma filled tubules that extend from chloroplasts (stromules) in the cells adjacent to signalling cells. This dataset s a deposit of all the raw microscopy images of the study, plus the relevant metadata in ISA-tab compliant folder structure. After receiving reviews, we have made an additional experiment using a ROS inhibitor. The raw and processed data for this is in a separate file: _S_chlROS_inhibitor.zip cell signalling chloroplasts microscopy ISA-tab potato virus Y redox responses cell death spatiotemporal analysis krompir krompirjev virus Y stromule analize slik mikroskopija celična smrt prostorsko-časovne analize true false true Zenodo Angleški jezik Slovenski jezik Neznano 2025-10-24 14:40:02 2025-10-24 14:40:02 2025-10-25 03:54:09 0000-00-00 00:00:00 2021 0 Genève 2021 Genève Nasl. z. nasl. zaslona; Opis vira z dne 14. 8. 2025; Soavtorji: Gruden, Kristina; Županič, Anže; Mahkovec Povalej, Tjaša; 1 spletni vir 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.2 10.5281/zenodo.6417635 245652995 https://doi.org/10.1111/nph.18425 0 928153f0-b0d6-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35528 https://doi.org/10.5281/zenodo.6417635 1 91e1b0f2-b0d6-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35527 Nacionalni inštitut za biologijo 0 0 0
