Abstract
Pšenica je zbog izloženosti nametnicima podložna raznim bolestima, među kojima je i Fusarijska palež klasa uzrokovana fitopatogenim gljivama roda Fusarium. Biljke su zbog svoje sesilne prirode razvile razne obrambene mehanizme, od kojih se neki temelje na sekundarnim metabolitima, produktima sekundarnog metabolizma. Prvi korak u sintezi sekundarnih metabolita katalizira fenilalanin-amonij-liaza (PAL), koja započinje kaskadu reakcija čiji konačni produkt čine razne skupine spojeva sintetiziranih u svrhu obrane organizma. Cilj ovog istraživanja bio je odrediti utjecaj inokulacije vrstama roda Fusarium na aktivnost PAL-a u klasovima ozime pšenice, u uvjetima različite gnojidbe dušikom, kao i korelaciju aktivnosti PAL-a sa sadržajem ukupnih fenola. Inokulacija vrstama roda Fusarium imala je značajan utjecaj na aktivnost PAL-a i sadržaj ukupnih fenola u klasovima pšenice. Sorte Graindor i Apache, koje su okarakterizirane kao djelomično otporne, imale su povećane aktivnosti PAL-a kao i sadržaj fenola, što ukazuje na važnu ulogu fenolnih spojeva u obrambenom odgovoru i boljoj tolerantnosti na patogene.
Abstract (english)
Due to exposure to pathogens, wheat is susceptible to various diseases, including Fusarium head blight caused by phytopathogenic fungi of the genus Fusarium. Due to their sessile nature, plants have developed various defense mechanisms based on secondary metabolites, products of secondary metabolism. The first step in synthesizing secondary metabolites is catalyzed by phenylalanine-ammonium lyase (PAL), which starts a cascade reaction whose final product consists of various groups of compounds synthesized for organism defense. This research aimed to determine the impact of the Fusarium inoculation on the activity of PAL in winter wheat spikes under conditions of different nitrogen fertilization, as well as the correlation of PAL activity with the content of total phenols. Fusarium inoculation significantly affected the PAL activity and the content of total phenols in wheat spikes. The varieties Graindor and Apache, characterized as partially resistant, had increased PAL activity and phenolic content, indicating the important role of phenolic compounds in the defense response and better tolerance to pathogens.
