What makes a peach a peach and a nectarine a nectarine? A single genetic mutation!

Trying to document grad school one YouTube video at a time, from lab equipment to genetics lessons to interviews with other students! Each week is a new view into life as a grad student, and the rollercoaster that is getting a PhD.

I just felt educated with a PhD. In Botany after watching this video. ,😅
Thanks for the simple breakdown of the information. İt was very helpful.

I'm loving your channel! (I have found it through the "Valentine's day" video by Inés!) In particular this video is great! I have only taken a very basic introductory course in cell and molecular biology, and I have found it amazing to have it all shown in a practical example in the lab! And I believe that it is the first time that I could understand how the game of dominant and recessive gens work at the molecular (DNA) level. I would love if you could make a video explaining how PCR works in more detail (as you somehow have promised in this video!)

Who is going to bring in those mutant peaches; bring them into justice?

I wonder if this is really the only difference. I feel like even if this is the only genetic change nectarines are usually picked/sold smaller and firmer.

Ok, I have one: but it's not about fruits, it's about flowers. Do you know "petunia night sky"? It's a recent (I think) cultivar and I was wondering about the genetic and molecular mechanism that makes possible this beautiful pattern in flowers. Maybe has something to do with transposons?

For summer themes, could do beach science? If you have a beach handy. Ooh or drought tolerance inducing endophytes, that's a bit planty/summery

Does the fuzz/no fuzz gene affect size? Peaches seem to be bigger than nectarines in the shops here (although yours look similar sizes)

Hey, could you do Hybrids? like Plumcot or something?

Wonderful, nice video. Thank you!
I am always amazed that 60 years ago, we didn't even know yet how genetic information is encoded, and these days we are able to isolate pieces like here, or even can calculate how a folded protein might look like. Science is amazing.

So, if pollen from a homozygous peach were to fertilize a nectarine flower, would the fruit be fuzzy or not? I'm thinking not. Nectarine trees produce nectarines.

It would be cool to talk about CAM plants or C4 plants as alternatives to C3 photosynthesis. Maybe get some pineapples (CAM plants) in there if you want to continue the fruit theme

But if that's all it is how come the insides taste slightly different..? Peaches tend to be more juicy and softer, plus a slightly different overall taste inside
