Abstract
Fitopatogena gljiva Puccinia triticina uzrokuje lisnu hrđu pšenice, sve češću i razorniju bolest pšenice u svijetu, stvarajući tako velike agronomske i ekonomske gubitke u proizvodnji pšenice. Uzgoj rezistentnih kultivara pšenice predstavlja najisplativiji i ekološki najprihvatljiviji pristup u kontroli ove bolesti. Rezistentne biljke posjeduju različite mehanizme obrane, pri čemu je aktivacija ili represija gena koji sudjeluju u tom odgovoru regulirana različitim signalnim putevima koji uključuju fitohormone kao što je salicilna kiselina (SA). Cilj je ovog istraživanja odrediti molekularni odgovor klijanaca šest sorti pšenice na infekciju lisnom hrđom. Infekcija klijanaca značajno je inducirala obrambene mehanizme pšenice, koji uključuju ekspresiju gena povezanih s patogenezom, gena uključenih u metabolizam SA, ekspresiju transkripcijskih faktora, te sintezu fenolnih spojeva. Učinak infekcije ovisio je o genotipu pšenice, pri čemu se sorte Demetra i Antonija, s obzirom indukciju molekularnog odgovora, izdvajaju kao otpornije, dok su sorte OS Olimpija i Felix osjetljivije. Istraživanje doprinosi razumijevanju molekularnih mehanizama tolerancije pšenice na lisnu hrđu, što je je iznimno važno za uspješan razvoj i selekciju tolerantnih genotipova pšenice.
Abstract (english)
The phytopathogenic fungus Puccinia triticina causes wheat leaf rust, an increasingly prevalent and destructive disease of wheat worldwide, resulting in significant agronomic and economic losses in wheat production. Cultivating resistant wheat cultivars is the most cost-effective and environmentally sustainable approach to controlling this disease. Resistant plants possess various defense mechanisms, where the activation or repression of genes involved in this response is regulated by different signaling pathways, including phytohormones such as salicylic acid (SA). This research aims to determine the molecular response of six wheat varieties seedlings to leaf rust infection. The infection of seedlings significantly induced defense mechanisms in wheat, including the expression of genes associated with pathogenesis, genes involved in SA metabolism, the expression of transcription factors, and the synthesis of phenolic compounds. The effect of the infection depended on the wheat genotype, with the Demetra and Antonija varieties standing out as more resistant due to their pronounced induction of the molecular response, while the OS Olimpija and Felix varieties were more susceptible. This research contributes to understanding the molecular mechanisms of wheat tolerance to leaf rust, which is crucial for the successful development and selection of tolerant wheat genotypes.
