Transcriptional control of strawberry ripening - Two to tango

Abstract

Although many genomic regions encoding putative transcription factors have been identified in sequencing efforts, the roles of relatively few have been elucidated. Now, working with strawberry, Molina-Hidalgo et al. (2017) have identified a second transcription factor (FaDOF2) involved in regulating eugenol synthase and production of the aroma compound eugenol during strawberry ripening. Not only is this important in understanding the control of ripening in non-climacteric fruit but, potentially, in breeding to reintroduce flavor into modern germplasm.
