Re: [DIYbio] Re: Tannin genes

Im hitting the books on any known tannin biosynthesis pathway in M. Pudica and maybe find the ID of the theorized tannin that controls one aspect of the mechanically induced turgor pressure loss. Just excising the cells and maintaining a stable culture of pulvini cells is a pain but Ive got some progress. Eventually I would like to isolate and somehow cassette the genes required for mechanoreception. Think touch and glow :) Ambitious goal but interesting nonetheless. I see everyone and their mother focusing on glowing plants but far less on movement.

Very cool!

I had to look up the latin name but those weeping ferns are familiar, have seen a few around.  It's always neat when the way an organism behaves still isn't fully understood.   Be interested to see what you can find out.

One if the few questions here I've felt qualified to comment on, tannins are actually a broad class of compounds (you probably know this). Perhaps you could deactivate the production of Gallic acid, or maybe of catechin/epicatechin. Both if these are well characterized metabolites necessary for the production of complex tannins. AFAIK the production of large tannic avid polymers or proanthocyanins is poorly understood even though there are indicators of enzymatic control.

> Any clue on the sequence of tannin producing genes? In working with mimosa pudica atm and have a hunch about tannins in the pulvini cells and their relation to mechanosensory responses. I want to silence the genes for tannin production and see if that shuts off movement. Ill do a genbank search in tandem but was curious as to the group's thoughts on the matter.
