RESPONSE OF MDR1 AND PDR1 ATP-BINDING CASSETTE-TYPE TRANSPORTER GENES TO BIOTIC SIGNALS IN WHEAT FLAG LEAF TIPS

Abstract

ATP-binding cassette-type (ABC) transporters are highly implicated in detoxification processes but not restricted to detoxification processes. Several ABC transporters including wheat Lr34 were shown to function in plant defense responses and secretion of plant antimicrobial compounds. Members of multidrug resistance (MDR) proteins and pleiotropic drug resistance (PDR) proteins were studied in wheat. MDR1 and PDR1 expression was relatively stable in all the developmental stages but responded differentially to salicylic acid and fumonisin B1. In silico analysis indicated that both MDR1 and PDR1 had expression levels in all analyzed parts of wheat.
