Convergence and constraint in glucosinolate evolution across the Brassicaceae.

ABSTRACT: Diversity in plant specialized metabolites plays critical roles in plant-environment interactions. In longer evolutionary scales, e.g. between families or orders, this diversity arises from whole-genome and tandem duplication events. Less is known about the evolutionary patterns that shape chemical diversity at shorter scales, e.g. within a family. Utilizing the aliphatic glucosinolate pathway, we explored how the genes encoding the terminal structural modification enzyme GSL-OH evolved across the Brassicaceae and the genomic processes that control presence-absence variation of its products (R)-2-hydroxy-but-3-enyl and (S)-2-hydroxy-but-3-enyl glucosinolate. We implemented a phylo-functional approach to functionally validate GSL-OH orthologs across the Brassicaceae and used that informatio
