Novel lignin-based extracellular barrier in glandular trichome
This is a fascinating story by Hao et al., which takes us from phenotype to novel insights by looking at glandular trichomes in cucumber. Cucumber fruits often have a silica-based white powder deposited on their surface, but this is missing from the yellow green peel (ygp) mutant. Staining shows that…

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…

Single-residue substitution in histone H3 leads to over-lignification in Arabidopsis
Chromatin changes are at the core of plant development and adaptation, as they constitute a crucial layer of gene expression control. The effects of different chromatin marks have historically been studied through mutations to the protein complexes depositing and removing the marks, which results in…
