Strategija razvoja biosenzorjev imunskega odziva v krompirju

Kadar rastlina doživi stres, naj bo biotskega ali abiotskega izvora, v ogroženih celicah pride do imunskega odziva. Informacija o vrsti stresa se prenese med celicami s hormoni in drugimi signalnimi molekulami, ki nastajajo med celičnim imunskim odzivom. Imunski odziv lahko spremljamo v tkivu skozi ...

Jasmonic acid and salicylic acid interact to determine spatial regulation of gene expression responses in potato leaf to herbivory by Colorado potato beetle and mechanical wounding
Valentina Levak, Tjaša Mahkovec Povalej, Karmen Pogačar, Katja Stare, Maja Zagorščak, Tim Hawkins, Joanne Robson, David Dobnik, Tjaša Lukan, Kristina Gruden
Izvirni znanstveni članek
Oznake: koloradski hrošč;jasmonska kislina;krompir;odziv rastlin na ranjenje;salicilna kislina;Colorado potato beetle;herbivore;hormonal crosstalk;jasmonic acid;potato;salicylic acid;wounding;
We investigated the spatial dynamics of potato (Solanum tuberosum) responses to herbivory and mechanical wounding. We first followed the spatiotemporal response of jasmonic acid (JA) signaling, known to be involved in the response. We generated two potato sensor lines: a JAZ degradation sensor and a ...

MicroRNA 160 controls the auxin response factor–class III peroxidase module and couples salicylic acid and redox signaling networks in the potato hypersensitive response to potato virus Y

Oznake: hypersensitive response;miR160;PVY;redox;salicylic acid;Solanumtuberosum (potato);sRNA;thermotolerance;
Hypersensitive response (HR) is an effector-triggered immune response leading to pathogen restriction and local cell death. Small RNAs (sRNAs), mediating RNA silencing, have a well-established role in antiviral immunity; however, their role in HR has not been addressed to date. We applied a spatiall ...

Functionality of potato virus Y coat protein in cell-to-cell movement dynamics is defined by its N-terminal region
Anže Vozelj, Tjaša Mahkovec Povalej, Katja Stare, Magda Tušek-Žnidarič, Katarina Bačnik, Valentina Levak, Ion Gutierrez-Aguirre, Marjetka Podobnik, Kristina Gruden, Anna Coll Rius, Tjaša Lukan

Oznake: krompirjev virus Y;krompir;plaščni proteini;gibanje virusa;točkovne mutacije;potato virus Y;potato;coat proteins;viral movement;point mutations;
Potato virus Y (PVY) is one of the top 10 economically most important plant viruses and responsible for major yield losses. We previously suggested the involvement of the N-terminal region of PVY coat protein (CP) in PVY spread. By constructing different N-terminal deletion mutants of the PVY N605 s ...

Erylysin A (EryA), an aegerolysin protein produced by the edible king oyster mushroom (Pleurotus eryngii), interacts strongly with an invertebrate-specific membrane sphingolipid ceramide phosphoethanolamine. Recently, a fluorescently fused variant of EryA was shown to bind to artificial and bacterial l ...
