In a new paper deposited at bioRxiv, we have investigated whether the plant model species Arabidopsis thaliana has antisense transcription - so called PROMPTs - at promoter regions - a feature that most non-plant eukaryotes seem to have. We found that most promoter regions in Arabidopsis do not have detectable PROMPTs even when multiple RNA degradtion systems are made non-functional, there are at least 100 clear cases of bona fide PROPMTs. We also see enhancer like signatures. Great work with Axel Theiffry and Peter Brodersen lab.
