Two ABA-responsive transcription factors reset the requirement for vernalization by re-activating FLOWERING LOCUS C in embryos

Xu et al. identify two transcription factors that activate FLOWERING LOCUS C during embryogenesis, thus re-setting the requirement for vernalization. https://doi.org/10.1093/plcell/koac077  By Guokai Xu, Zeng Tao and Yuehui He Peking University Institute of Advanced Agricultural Sciences Peking-Tsinghua…

An RNA splicing factor regulates temperature-responsive flowering

Chang et al. discover the role of an evolutionarily conserved splicing factor in regulating temperature-responsive flowering in Arabidopsis. Background: Eukaryotic genes contain non-coding sequences termed introns that intervene between coding sequences. After being transcribed into pre-mRNA, these…

Florigen sequestration in cellular membranes modulates temperature-responsive flowering (Science)($)

The existence of the FLORIGEN – a mobile floral activator produced in the leaf and transported to the apex – was hypothesized almost a century ago but its molecular nature remained elusive for decades. In the last 15 years, independent groups demonstrated that members of the Phosphatidyl Ethanolamine-Binding…

DELLA degradation by gibberellin promotes flowering via GAF1-TPR-dependent repression of floral repressors in Arabidopsis (Plant Cell)

In Arabidopsis, flowering is promoted by the activation of the florigen FT in response to long days and by the accumulation of the phytohormone GA under short days (SD). Despite the extensive knowledge of regulatory networks involving FT, the molecular mechanism controlled by GA is still unresolved.…
