When do leaves commit to their phenotypic fate? Developmental point of no return on the early leaves from the det2-1 mutant of Arabidopsis thaliana

The Arabidopsis thaliana det2-1 mutant is widely studied due to its characteristic dwarf phenotype, which arises from its inability to efficiently synthesize brassinosteroids. This deficiency results in distinct leaf morphology compared to the wild-type Columbia (Col-0) plants. Notably, the det2-1 p...
