In this interview, he reveals his next project: Paintunia, a petunia that acts as a living canvas. These petunias have an inducible gene; when you lightly touch a bud (before it opens) with a clear molecule, called dexamethasone, that molecules seeps into cells, switches on the gene, and causes them to make a pigment. The result is a paintable flower, where molecules are literally used to control which colors show up in which places. For a prior project, Nick turned Arabidopsis, a small (and quite ugly) plant widely used in research, into little pink “micro-roses.”\n\nWe filmed this episode surrounded by flowers, with Nick walking me through how each one gets its shape and pigmentation. He explained how he combines breeding and genetic engineering to make flowers, and how he searches scientific papers for mutations to figure out which plant crosses to make next. His ultimate dream is to build a botanical garden filled with weird and wonderful flowers that exist nowhere else.
