20.500.12556/DiRROS-19351 The physiological impact of GFLV virus infection on grapevine water status first observations In a vineyard, grapevines are simultaneously exposed to combinations of several abiotic (drought, extreme temperatures, salinity) and biotic stresses (phytoplasmas, viruses, bacteria). With climate change, the incidences of drought in vine growing regions are increased and the host range of pathogens with increased chances of virulent strain development has expanded. Therefore, we studied the impact of the combination of abiotic (drought) and biotic (Grapevine fanleaf virus (GFLV) infection) stress on physiological and molecular responses on the grapevine of cv. Schioppettino by studying the influence of drought and GFLV infection on plant water status of grapevines, on grapevine xylem vessel occlusion, and on expression patterns of 9-cis-epoxycarotenoid dioxygenase 1 (NCED1), 9-cis-epoxycarotenoid dioxygenase 2 (NCED2), WRKY encoding transcription factor (WRKY54) and RD22-like protein (RD22) genes in grapevines. A complex response of grapevine to the combination of drought and GFLV infection was shown, including priming in the case of grapevine water status, net effect in the case of area of occluded vessels in xylem, and different types of interaction of both stresses in the case of expression of four abscisic acid-related genes. Our results showed that mild (but not severe) water stress can be better sustained by GFLV infection rather than by healthy vines. GFLV proved to improve the resilience of the plants to water stress, which is an important outcome to cope with the challenges of global warming. grapevine water status virus infection GFLV xylem vessel occlusion gene expression vinska trta virusne okužbe GFLV izražanje genov true false true Angleški jezik Slovenski jezik Neznano 2024-07-16 05:09:49 2024-07-16 05:09:49 2024-07-17 03:59:13 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Soavtorji: Maja Rupnik-Cigoj, Marija Stele, Marko Chersicola, Maruša Pompe-Novak, Paolo Sivilotti; Opis vira z dne 12. 1. 2022; Št. članka: 161; str. 1-15 iss. 2 Vol. 11 January 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-07 578 2223-7747 10.3390/plants11020161 93001987 https://www.mdpi.com/2223-7747/11/2/161 1 dfc24e16-4320-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26680 RAZ_Jez_Krebelj_Anastazija_2022.pdf RAZ_Jez_Krebelj_Anastazija_2022.pdf 1 F5D9A2C7F1F3CA6D98AE1F09629636ED a50d3e9e4f8f34d12fc7a9c7631f6db2655f52d68b18cb9311581446c66b980c 31343eca-4321-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26681 Nacionalni inštitut za biologijo 0 0 0
