Flowering locus m
WebChanges in ambient temperature affect flowering time in plants; understanding this phenomenon will be crucial for buffering agricultural systems from the effects of climate change. Here, we show that levels of FLM-b, an alternatively spliced form of the flowering repressor FLOWERING LOCUS M, increase at lower temperatures, repressing … WebNational Center for Biotechnology Information
Flowering locus m
Did you know?
WebIts regulatory partner, FLOWERING LOCUS M ( FLM )- β, is the product of alternative splicing of transcripts from the gene encoding FLM that favors the β form at lower temperatures. SVP and FLM-β form a complex that represses flowering. At lower temperatures, more of the repressive complex is present and flowering is delayed. WebFlorigen (or flowering hormone) is the hypothesized hormone-like molecule responsible for controlling and/or triggering flowering in plants. Florigen is produced in the leaves, and acts in the shoot apical meristem of buds and growing tips. It is known to be graft-transmissible, and even functions between species. Florigen has been found identical to …
WebDec 12, 2024 · The maintenance of the silenced chromatin state at the FLC locus in warm conditions after prolonged cold exposure enables plants to flower in spring when days become longer, but the “memory of winter cold” must be erased or reset in offspring to ensure that next generation must overwinter again prior to spring flowering (Amasino … WebJan 5, 2024 · 2.1 Florigen. The model plant Arabidopsis is an excellent material for studying flowering control because of its short life cycle and the various tools available for genetic studies. Floral transition in Arabidopsis is controlled by photoperiod, ambient temperature and vernalization. Among the regulatory networks, the FT gene is the strongest …

WebOct 1, 2024 · Interestingly, Bao et al. [33] showed that CO and MYC3 compete for binding to the FT locus explaining their antagonistic behavior. Furthermore, they mutated the MYC3 binding site at the FT locus, phenocopying myc3 early flowering. This is a nice example of signal integrations at the promoter level, and how they might be tested by genome editing.
