Florigen controls its own production to fine-tune flowering | Plantae
Flowering at the right time is essential for plants to balance vegetative growth and reproduction. In Arabidopsis, long days induce CONSTANS (CO) to activate the transcription of FLOWERING LOCUS T…

Here’s the clue that got us interested:
Without the systemic flowering signal #florigen (sft), tomato still flowers - but vSYM initiation is strongly delayed.
So #floraltransition and its associated reprogramming of shoot architecture can be genetically uncoupled!

Our work reveals a broader role for florigen in coordinating shoot growth at floral transition, while local inputs tune parallel meristem programs to shape architecture.
Dedicated to Prof. Eliezer Lifschitz (Technion), who shared with us his curiosity, creativity and wisdom.

Our emerging model suggests that apical AMs activate a common PUCHI/LOB30 programme through distinct inputs. vSYM is strongly florigen (SFT)-dependent, while rSIM relies more on UNIFLORA. Partially independent control provides developmental flexibility to shape shoot architecture.

Florigen-producing cells express FPF1-LIKE PROTEIN 1 to accelerate flowering and stem growth in Arabidopsis
Takagi and Lee et al. show that florigen-producing cells express unique transcripts not found in other phloem cells by analyzing transcripts translated into proteins. One such transcript encodes FLP1,...

Saturday Morning editing, working on explaining what florigen is. Also, apparently however long you think it takes to animate something, like double it. #pngtuber, #vtuber

The "tourism industry" is the largest industry in America, it employees more people & generates more tax dollars than any other industry in America. Florigen tourists spend the most money when they take vacations, which means they are more highly treasured the domestic tourists.

Okay, so in plant physiology molecular geneticist Chailakhyan of Florigen fame was actually reinstated in 1953 - under de jure rule of Lysenko and during Stalin's life, as I learnt from book on his life edited by GP, so in certain areas of science Lysenkoism lasted barely over 4 years.
If we are to compare Lysenkoism in USSR to any social phenomenon in contemporary USA, it would have been the ban on federal funding studies covering effects of gun lobby on people - except Lysenko lasted 6 years, and this one lasted decades.

Florigen genes are central to the floral transition in rice, but their full role remains underexplored. This study reveals a two-phase action of Hd3a and RFT1, showing how low and high florigen levels distinctly regulate developmental timing and floral induction.

16/ It turns out that the evolution of flowers - a "relatively modern" invention - took a much more complicated route than primitive plants. Rather than simple molecules (ethylene has only two carbons!), florigen involves transportable *proteins*.

14/ Strigolactones affect branching and also function as a means of communication with mycorrhizæ in the soil (discussed here):

And so forth.

But for much of a century, one key hormone eluded us - the fabled "Florigen".

Until now.

But these sorts of things were easy to find, because they're simple compounds, and we're coming to understand that it's not nearly that simple. We've probably *finally* found for example the long-theorized "florigen" (the hormone to cause flowering), and it's a complex series of proteins.

Our single nucleus RNA-seq work targeting companion cells expressing florigen is finally out. In @elife.bsky.social: Companion cells with high florigen production express other small proteins and reveal a nitrogen-sensitive FT repressor doi.org/10.7554/eLif...
Companion cells with high florigen production express other small proteins and reveal a nitrogen-sensitive FT repressor
A distinct subset of leaf companion cells expresses high levels of the florigen gene, and the same cells also produce other possible mobile floral regulators and small proteins.
