The NAC transcription factor FaRIF controls fruit ripening in strawberry. Plant Cell. 2021 Jul 2;33(5):1574-1593. doi: 10.1093/plcell/koab070. PMID: 33624824; PMCID: PMC8254488. https://hdl.handle.net/10630/29630 10.1093/plcell/koab070 In contrast to climacteric fruits such as tomato, the knowledge on key regulatory genes controlling the ripening of strawberry, a nonclimacteric fruit, is still limited. NAC transcription factors (TFs) mediate different developmental processes in plants. Here, we identified and characterized Ripening Inducing Factor (FaRIF), a NAC TF that is highly expressed and induced in strawberry receptacles during ripening. Functional analyses based on stable transgenic lines aimed at silencing FaRIF by RNA interference, either from a constitutive promoter or the ripe receptacle-specific EXP2 promoter, as well as overexpression lines showed that FaRIF controls critical ripening-related processes such as fruit softening and pigment and sugar accumulation. Physiological, metabolome, and transcriptome analyses of receptacles of FaRIF-silenced and overexpression lines point to FaRIF as a key regulator of strawberry fruit ripening from early developmental stages, controlling abscisic acid biosynthesis and signaling, cell-wall degradation, and modification, the phenylpropanoid pathway, volatiles production, and the balance of the aerobic/anaerobic metabolism. FaRIF is therefore a target to be modified/edited to control the quality of strawberry fruits. eng http://creativecommons.org/licenses/by/4.0/ open access Atribución 4.0 Internacional Fresas - Maduración Genética vegetal The NAC transcription factor FaRIF controls fruit ripening in strawberry. journal article
