- Gabriel Wu 17:40, 25 February 2013 (EST): There's a reasonable amount of history of optogenetics in synthetic biology as well. Here's a few papers to check out (there's even a UT connection!).

- Alvaro E. Rodriguez M. 21:35, 28 February 2013 (EST): Another comment, it's important to say what an acronym means, example, I don't know what PRC is, etc....I google it but you get the point, I bet. Also in the table you might want to add the wavelength (i.e. ....nm) that each of these rhodopsins absorbs, meaning if it says Yellow (600 nm). Also do all bacteriorhodopsins absorb yellow light only?
