Benzoxazinoids - protective secondary metabolites in cereals: The role and application
Benzoksazinoidi - zaštitni sekundarni metaboliti žitarica - uloga i primena
Апстракт
Benzoxazinoids (BXs) are secondary plant metabolites that provide innate defence against a plethora of pests and pathogens. They are identified both in monocots, namely grasses, and in several families of dicots. Among crops, BXs are best characterised in wheat, maize, and rye. These natural pesticides have inhibitory effects on weeds, insects, plant pathogenic fungi, bacteria, and nematodes. Besides, BXs demonstrated the ability to suppress production of mycotoxins, mitigate negative effects of microelement deficiency and toxicity and attract plant beneficial bacteria in the rhizosphere. Here, we summarise benefits and possible applications of these allelochemicals in pest control, which may be of special interest for production systems based on reduction or elimination of pesticides, such as integrated pest management or organic farming. In the light of it, we discuss possible limitations and risks of BX application that are worth considering. Finally, we refer to available germplasm... with high BX level that can be exploited as a source of resistance in cereal breeding programmes.
Benzoksazinoidi su sekundarni metaboliti biljaka koji obezbeđuju zaštitu od brojnih štetočina i patogena. Utvrđeni su kod monokotila, poput trava, i nekoliko porodica dikotila. Među usevima, benzoksazinoidi su najbolje opisani kod pšenice, kukuruza i raži. Ovi prirodni pesticidi imaju inhibitorno dejstvo na korove, insekte, fitopatogene gljive, bakterije i nematode. Pored toga, benzoksazinoidi pokazuju sposobnost da potisnu stvaranje mikotoksina, ublaže negativno dejstvo nedostatka mikroelemenata i toksičnosti i privuku korisne bakterije u rizosferi useva. U ovom radu, sažete su prednosti i mogućnosti primene ovih alelojedinjenja u zaštiti žitarica, ukazujući na njihov značaj u proizvodnji sa integralnim merama zaštite u kojoj je smanjena upotreba pesticida, ili u organskoj proizvodnji u kojoj se pesticidi ne koriste. S tim u vezi, razmatraju se moguća ograničenja i rizici primene benzoksazinoida. Konačno, ukazuje se na dostupnu germplazmu sa velikim sadržajem benzoksazinoida koja može... poslužiti kao izvor otpornosti u oplemenjivačkim programima žitarica.
