OK @calacademy.bsky.social, saw this DNA sequence in an exhibit today, assumed green=A, blue=C, red=T, black=G, and tried to BLAST it to figure out its origin but have so far turned up nothing. What species and gene is this sequence from? Claude didn't know either.

You say I’m trying to poison my lab with ammonium chloride. I say I’m just offering up some Finnish treats.

Brilliant use of gfp-tagged transposons & automated scoring of kernels, combined with differential style-lengths along maize ear, to screen for genes underlying pollen competition in maize. Diana gave a banger of a presentation on this in #Zeavolution this morning. www.biorxiv.org/content/10.1...
