Abstract
Viroids are plant–pathogenic molecules characterized by a single–stranded circular non–coding RNA genome. Despite their genomic simplicity, these plant pathogens are able to induce disease in a wide range of host plants with significant economic impact. The surveillance activities described in this study, revealed the presence of Potato spindle tuber viroid (PSTVd) in Croatia in two ornamental species, while no PSTVd infection was found in tomato or potato. This study was also aimed to evaluate the effects of PSTVd infection on endogenous plant growth regulator (PGR) content, and to identify common, but also specific, features of systemic hormonal response in solanaceous plant species in which PSTVd causes different degrees of symptoms. Endogenous brassinosteroide castasterone, salicylic acid, abscisic acid, indole–3–acetic acid, jasmonic acid and its precursor cis–12–oxophytodienoic acid were quantified using UHPLC–MS/MS. The study provides new evidences about the involvement of different PGRs and antioxidant enzymes in plant defense response against PSTVd infection, in both symptomatic and asymptomatic solanaceous species.
Abstract (croatian)
Viroidi su najmanji poznati uzročnici bolesti biljaka čiji genom karakterizira nekodirajuća jednolančana kružna molekula RNA. Unatoč njihovoj jednostavnosti, ovi biljni patogeni uzrokuju bolesti mnogih kultiviranih biljaka širom svijeta, kao i značajne ekonomske gubitke. Bolest uzrokovana viroidom vretenastoga gomolja krumpira (Potato spindle tuber viroid, PSTVd), otkrivena je u okviru redovitih nadzornih aktivnosti u dvije ukrasne vrste u Hrvatskoj, dok zaraza u rajčici i krumpiru nije potvrđena. Cilj ovog istraživanja ujedno je bio ispitati utjecaj zaraze viroidom vretenastoga gomolja krumpira na biljne regulatore rasta te odrediti zajedničke, kao i vrsno specifične značajke hormonskog odgovora u vrstama iz porodice Solanaceae koje pokazuju različite simptome bolesti. Izmjeren je sadržaj endogenog brasinosteroida kastasterona, salicilne kiseline, apscizinske kiseline, indol–3–octene kiseline, jasmonske kiseline i cis–12–oksofitodienoične kiseline, primjenom UHPLC–MS/MS metode. Ova studija daje nove dokaze o ulozi biljnih regulatora rasta i antioksidacijskih enzima uslijed staničnog odgovora biljke na zarazu viroidom PSTVd
