Abstract

Mikoriza je oblik mutualističkog odnosa uspostavljen između korijena biljaka i hifa gljiva. Posljedica tog odnosa jesu podzemna umreženja micelija koja spajaju pripadnike istih, ali i različitih vrsta. Smatra se kako su mikorizna podzemna umreženja kanali za prijenos informacija između biljaka. odnosno posreduju komunikaciji između biljaka. Mikorizne mreže provode biokemijske signale koji induciraju određene obrambene odgovore u biljkama. Nije još uvijek potvrđeno koji su to signali, ali se nagađa kako bi jasmonka i salicilna kiselina ili pak tvari lipofilnog karaktera mogle preuzeti tu ulogu. Putem podzemnih mikoriznih mreža biljke mogu proširiti područje bioaktivne zone djelovanja raznih signala koji sudjeluju u biljnom obrambenom sustavu, alelopatiji, otpornosti na razne bolesti i nametnike te se ovim mrežama mogu prenositi i nutrijenti poput fosfora, dušika i ugljika. Podzemne mikorizne mreže stoga imaju veliku ulogu u komunikaciji između biljaka koja je vrlo ključan element po pitanju obrane od napada nametnika i samog opstanka biljke.

Abstract (english)

Mycorrhiza is a form of a mutualistic simbiotic relation established between the roots of plants and hyphae of fungi. Due to this relation, underground hyphal networks are moulded. In proffesional literature these types of hyphal networks are often called “common mychorrhizal networks”-CMN, which refers to the fact that they are a linkage between members of the same and also of different species. It is believed that common mychorrhizal networks are a channel that mediates communication between plants. Mycorrhizal networks conduit biochemical signals that induce specific defense responses in plants. Although these compounds remain unknown, there are some speculations that jasmonic and salicic acid, or perhaps some lipid compounds could take the role. Through a network of underground mycorrhizal networks, plants can extend the bioactive zone for various signals involved in plant defense system, allelopathy, resistance to various diseases and pests. Also CMNs can transmit nutrients such as phosphorus, nitrogen and carbon. Therefore, the CMNs have a key role in interplant communication as they are a conduit for information that help plants thrive and survive.
