Other claims from this paper (3)
- Mechanism Mutations in a cytokinin hormone biosynthetic gene caused at least 16 independent losses of prickles in eggplants and wild relatives in the genus Solanum.
- Mechanism Homologs of the cytokinin biosynthetic gene underlie prickle formation across angiosperms that diverged more than 150 million years ago, including rice and roses.
- Mechanism The authors conclude that a shared hormone activation genetic program underlies widespread and recurrent evolution of plant morphological innovation such as prickles.
