Persistent heat stress in Arabidopsis


ABSTRACT: Analysis of transcriptional changes upon persistent heat stress with emphasis on epigenetically regulated genes 3 week old seedling grown in vitro were exposed to 37oC for 30 h (LHS). After heat stress, plants were analyzed immediately (R0) or allowed to recover at ambient temperature for 2 days (R2).

Epigenetic factors determine responses to internal and external stimuli in eukaryotic organisms. Whether and how environmental conditions feed back to the epigenetic landscape is more a matter of suggestion than of substantiation. Plants are suitable organisms with which to address this question due to their sessile lifestyle and diversification of epigenetic regulators. We show that several repetitive elements of Arabidopsis thaliana that are under epigenetic regulation by transcriptional gene  ...[more]
