Abstract
U biološkim se istraživanjima često koriste modelni organizmi. Mahovina P. patens razmatra se kao novi modelni organizam u instraživanjima interkacije biljka – patogen. Cilj ovog seminarskog rada je opisati interakciju mahovine i pojedinih patogena (gljiva B. cinerea, oomicete P. debaryanum i P. irregulare, bakterija P. c. carotovorum i virus pjegavosti i venuća rajčice), usporediti proces infekcije različitih patogena i obrambene mehanizme koji se aktiviraju u mahovini nakon infekcije. Otkriveno je da spomenuti patogeni mogu inficirati mahovinu te pokrenuti obrambene mehanizme mahovine. Obrambeni mehanizmi su često inducirani signalnim molekulama poput SA i JA. Različiti patogeni različito interferiraju sa signalnim molekulama u mahovini P. patens. Rani odgovor na infekciju gljivom i oomicetama, kojim se nastoji spriječiti širenje gljive i oomiceta je akumulacija fenolnih spojeva u staničnu stijenku mahovine. Ugradnja fenolnih spojeva nije dovoljno učinkovita u sprječavanju infekciju. Druga metoda obrane od gljive, bakterije i oomiceta je programirana stanična smrt mahovine koja je karakterizirana odumiranjem stanica i karakterističnim staničnim promjenama. Infekcije gljivom i oomicetama uzrokuje proizvodnju ROS. Mahovina P. patens je podložna infekciji virusom pjegavosti i venuća rajčice te su u tkivu mahovine pronađena dva virusna proteina. Pronalazak proteina pretpostavlja da je u tkivu mahovine u potpunosti repliciran i prepisan genom virusa što može rezultirati sklapanjem novih virusnih čestica.
Abstract (english)
In biological research we often use model organisms. Moss P. patens is considered as a new model organism in research on plant – pathogen interactions. Purpose of this seminar is to describe the interactions between moss and certain pathogens (fungus B. cinerea, oomycetes P. debaryanum and P. irregulare, bacteria P. c. carotovorum and Tomato spotted wilt virus), to compare the process of infection of various pathogens and defense mechanisms that are activated in moss after infection. It has been discovered that these pathogens can infect moss and induce defense mechanisms in moss. Defense mechanisms are often induced by signal molecules such as SA and JA. Different pathogens interfere with different signal molecules in moss P. patens. Early response to infection by fungus and oomycetes, which aims to prevent the spread of fungus and oomycetes, is incorporation of phenolic compounds in the mosses cell wall. Incorporation of phenolic compounds is not enough efficient to stop infection. Another method of defense against fungus, bacteria and oomycetes is programmed cell death in moss which is characterized by cell death and characteristic cell changes. Infection with fungus and Oomycetes causes the production of ROS. Moss P. Patens is subject for Tomato spotted wilt virus infection. Two viral proteins were found in moss tissue after inoculation of virus. The discovery of the protein assumed that viral genome was replicated and transcribed which can direct assembly of new viral particels.
