indeed, i begin my grad lecture on RNAi/miRNAs by discussing petunias. and mentioning while none of our students will do a plant phd (no faculty), they can learn A LOT by occasionally reading plant literature (think epigenetics, small RNAs, developmental biology, etc etc). also, consider the worm!
The quest to make darker petunias led to a 2006 Nobel & a fundamental tool of modern molecular biology.

In 1986, Richard Jorgensen was trying to make a darker purple petunia to get some VC funding. So he inserted additional copies of the pigment gene into petunias.

Instead, they turned WHITE.

This is my favorite conceptual figure from a paper. It's stunning.

The image of a hypothetical plant represents a compendium of different types of galls and if also a key to the types of organisms that induce each type of gall. @newphyt.bsky.social
