Abstract
Salicilna kiselina pripada skupini fenolnih fitohormona visoke metaboličke i fiziološke aktvnosti. Dva su predložena puta biosinteze salicilne kiseline u biljaka: od fenilalanina deriviranim korizmatom pretvara se u trans-cimetnu kiselinu pomoću fenilalaninamonij- lijaze (PAL) i iz korizmata, putem izokorizmata u reakciji s dva koraka koja je katalizirana izokorizmat sintazom (ICS) i izokorizmat-piruvat lijazom (IPL). Jednom sintetizirana salicilna kiselina u biljkama prolazi kroz niz biološki relevantnih kemijskih modifikacija uključujući glukoziliranje, metiliranje i konjugaciju aminokiselina. Salicilna kiselina ima važnu ulogu u različitim procesima u biljkama kao što su rast i razvoj,termogeneza, fotosinteza, cvjetanje, unos i transport iona te stomatalna transpiracija. Salicilna kiselina ima ključnu ulogu kao signalna molekula u abiotičkom i biotičkom odgovoru na stres. Uključena je u endogenu signalizaciju, posredujući u obrani biljaka od patogena inducirajući proizvodnju proteina povezanih s patogenezom. Uključuje sustavnu stečenu otpornost u kojoj patogeni napad na jedan dio biljke inducira otpornost na drugim dijelovima, a prevođenjem salicilne kiseline u metil salicilat, hlapljivi ester, signal se može premjestiti i u obližnje biljke.
Abstract (english)
Salicylic acid (SA) is a phenolic phytohormone high metabolic and physiological activity. Two pathways of SA biosynthesis have been proposed in plants: from cinnamate produced by the activity of phenylalanine ammonia lyase (PAL) and from chorismate through two reactions catalysed by isochorismate synthase (ICS) and isochorismate pyruvate lyase (IPL).Once synthesized salicylic acid in plants passes through a series of biologically relevant chemical modification including glycosylation, methylation, and amino acid conjugation. Salicylic acid has physiological roles in plant growth and development, photosynthesis, transpiration, thermogenesis, flowering, ion uptake and transport and stomatal transpiration. SA is an important signal molecule in plants, mediating in plant defence against pathogens. It plays a role in the resistance to pathogens by inducing the production of pathogenesis-related proteins. It is involved in the systemic acquired resistance in which a pathogenic attack on one part of the plant induces resistance in other regions. The signal can also move to nearby plants by salicylic acid being converted to the volatile ester, methyl salicylate.
