The DOG 1 （DELAY OF GERMINATION 1） gene is the main QTL controlling this trait in Arabidopsis （Bentsink et al., 2006） and therefore is extensively regulated. This includes the alternative polyadenylation （APA） of DOG1 mRNA （Cyrek et al., 2016） and an antisense transcript, asDOGl, which in cis suppresses DOG1 expression during seed maturation （Fedak et al., 2016）. As with many antisense transcripts （Mellor et al., 2016; Rosa et al., 2016）, asDOG1 originates from close to the transcription termination site of the sense gene. This raises the question of how this proximity affects antisense promoter activity.展开更多
