Rewrite (April 2009)

I gave the article a pretty major rewrite and upgraded it to start class, although there's still a fair way to go with it. Here's a suggested to do list:

Expand Mechanism section to include more detailed information (esp. on regulation of CO expression and FT protein production/translocation)
Image showing complete pathway
Full research history
Graphs showing accumulation of CO mRNA, CO protein and FT mRNA during long and short days
Add new section on conservation of florigen between species

Any help/comments welcome. Ribrob (talk) 14:42, 6 April 2009 (UTC)[reply]

Is it still a mystery? Why?

The introduction currently (February 2012) states that florigen is still a mystery, but the article then seem to explain quite succintly what it is. So is it still a mystery? If so, I think the article should explain why. — Preceding unsigned comment added by 90.185.56.99 (talk) 11:00, 17 February 2012 (UTC)[reply]

Yes, it's still a mystery: although we've figured out a lot of what florigen does -- assuming it's a single molecule, which is not conclusively proven -- we haven't actually found florigen itself. So we don't know what it is. DS (talk) 17:20, 17 February 2012 (UTC)[reply]

Article lacks focus

The article doesn't read like an article about a plant hormone.

The "Mechanism" section in particular is rambling, spending most of its length talking about daylight duration and temperature, and not about florigen. It says "Florigen is a systemically mobile signal", which is overblown ("systemically" is meaningless in context, and calling any signal "mobile" is redundant since the capacity to propagate is the essential characteristic of a signal) while also not really saying anything about what it actually is. Compare this to how Melatonin is described in its article: "play[s] a role in regulating the sleep-wake cycle...", "melatonin acts as a full agonist...", "melatonin functions as a high-capacity antioxidant...". The language is concrete and direct.

Part of the problem is that the article dances around the fact that we don't know what it is, and it might not exist. This is essential information and should be stated up-front. For example, instead of the first line being:

Florigens (or flowering hormone) are proteins capable of inducing flowering time in angiosperms.

it should rather be put:

Florigen (or flowering hormone) is a theoretical protein, class of proteins or other substance which induces flowering in angiosperms. While recent findings indicate that florigen does exist and is produced in the leaves of the plant, it has yet to definitively isolated.
