Genetic Engineering to Make Annuals Become Perennials

I am absolutely fascinated by an article I recently read on about research to make annuals become perennials.

Arabidopsis thaliana

Researchers have found that only 2 genes, which are associated with flowering, control the development of perennial growth.  Altering these two genes, they have been able to make annual plants into perennial plants.   Of course, there are side effects (you can’t get something for nothing)…plants tend to not flower or, they flower much later after going through the change. So for now, to get our fix of bright splashes of color we will still have to shell every spring and summer.

If you are interested in this ongoing research here are a number of links to places where you can read more about it:
