What biochemicals are involved in seed dispersal/seed drop? - (Mar/31/2014 )
I am wondering what proteins/hormones/genes are involved in seed drop/seed dispersal. In particular, if elevated levels of proteins/hormones/genes can lead to premature seed drop/dispersal.
Ethylene plays a role in flower/fruit/leaf drop, however I'm more interested in something that more solely affects seed drop, without affecting flower production or leaf drop.
Then you are probably out of luck - most of the chemicals that I know of that are involved in abscission are also involved in leaf drop or fruit ripening - for good reason too, the roles are intimately linked.

If I had a lab and tons of grants it'd be fine, I could just do mass amounts of protein profiling and qRT-PCR, but for now all I have is available information on plant biochemistry, and compared to animals there seems to be little information.
