A dirigent protein complex directs lignin polymerization and assembly of the root diffusion barrier
In Latin, dirigere means “to align or guide”, so in 1997 when a protein was identified that guides the stereoselectivity of another enzyme it was named as a dirigent protein. Subsequent studies found that the Arabidopsis genome encodes 25 dirigent proteins (DPs). In this new work, Gao et al. characterized…
