Abstract
Isolation of high quality high molecular weight RNA from plant tissues is complicated by high levels of polyphenols and polysaccharides which bind to and/or coprecipitate with RNA Using high molecular weight polyethylene glycol HMWPEG RNA was successfully isolated from plant species in which other RNA extraction methods and commercially available kits failed to deliver suitable results We tested various buffer systems and isolation conditions with and without PEG or PVP polyvinylpyrrolidone using tissue from species ofAloe Ananas Clusia Euphorbia Kalanchoe Opuntia andPyrrosia all of which contain high amounts of phenolic compounds and/or polysaccharides HMWPEG was found to be more effective than PVP in removing these compounds RNA extraction using HMWPEG resulted in RNA of high quality from all species investigated as indicated by UV light absorption profiles and also yielded PCR amplification products after reverse transcription
