20.500.12556/RUL-167981 Raziskovanje vloge okužb rastlin z virusi pri povečanju tolerance na sušo Investigating the role of plant virus infections in increasing drought tolerance Virusne okužbe rastlin, ki so bile tradicionalno obravnavane kot škodljive, lahko v določenih okoliščinah, kot so sušni pogoji, preidejo v mutualizem in povečajo toleranco rastlin pri abiotskem stresu. V nalogi je narejen pregled molekularnih in fizioloških mehanizmov, ki so ključni pri toleranci rastlin na sušo, vključno z vlogo antioksidativnih encimov, kot sta SOD in katalaza, ter reaktivnih kisikovih spojin. Evolucijska prilagoditev virusov v sušnih razmerah kaže na spremembe v ekspresiji genov rastlin, ki spodbujajo toleranco do stresa, vključno z osmoregulacijo, hidracijo in zmanjšanjem oksidativnih poškodb. Ta pregled poudarja kmetijsko vrednost potencialne uporabe virusnih okužb kot načina za preprečevanje stresa zaradi suše in morda biološki nadomestek sistemom za namakanje in kemične dodatke. Čeprav študije odpirajo nova vrata za trajnostno kmetijstvo, je potrebnih še več analiz za razumevanje celotne slike okoljske škode in pa vseh morebitnih nevarnosti, ki jih vključuje evolucijska selekcija. Ta pristop ponuja večplasten pogled na sposobnost izkoriščanja naravnih mehanizmov za spopadanje s škodljivimi vplivi podnebnih sprememb. Plant viral infections, traditionally considered harmful, can, under certain conditions such as drought, transition into mutualism and enhance plant resistance to abiotic stress. This review focuses on the molecular and physiological mechanisms underlying this shift, including the roles of antioxidant enzymes such as SOD and catalase, as well as reactive oxygen species (ROS). The evolutionary adaptation of viruses to drought conditions reveals changes in the expression of plant genes that promote stress tolerance, including osmoregulation, hydration, and the reduction of oxidative damage. This review highlights the agricultural potential of utilizing viral infections as a means of mitigating drought conditions and possibly as a biological substitute for irrigation systems and chemical additives. While these studies open new avenues for sustainable agriculture, further work is required to understand the broader environmental impacts and potential risks associated with evolutionary selection. This approach offers a multifaceted perspective on harnessing natural mechanisms to address the adverse effects of climate change. virusne okužbe rastlin mutualistični odnosi sušni stres abiotski stres reaktivne kisikove spojine (ROS) antioksidativni encimi osmoprotektanti evolucija virusov molekularni mehanizmi signalne poti trajnostno kmetijstvo odpornost rastlin plant viral infections mutualistic relationships drought stress abiotic stress reactive oxygen species (ROS) antioxidant enzymes osmoprotectants virus evolution molecular mechanisms signaling pathways sustainable agriculture plant resistance true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-03-22 07:15:16 2025-03-22 07:15:23 2025-03-24 08:28:32 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 257180 229933315 47477.pdf 47477.pdf 1 E666B020EB3045EBF220CD91A2ED6755 5a22bbb13dca31a70438d102b50b527787b9401e9581215f40733c3703334aa0 0a393507-06e4-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200949 Biotehniška fakulteta 0 0 0
