TL;DR: Members of an Arabidopsis TOL (TOM1-LIKE) family are described as ubiquitin binding proteins that act redundantly in control of plant morphogenesis, suggesting a function for TOLs early in the passage of endocytosed ubiquitinated PM cargo, acting as gatekeepers for degradative protein sorting to the vacuole.

TL;DR: In roots, brassinolide can modulate vacuolar degradation and endocytic sorting of PIN2, delimiting root curvature in response to gravity.

TL;DR: Auxin metabolism profiling in BY-2 mutants carrying either siRNA-silenced or CRISPR-Cas9-mutated NtDAO1, as well as in dao1-1 Arabidopsis plants, showed not only the expected lower levels of oxIAA, but also significantly lower abundance of oxiaA-Asp, representing direct evidence of DAO1 activity on IAA amino acid conjugates.

TL;DR: This work identifies basic cellular activities connected to translational control of gene expression as sufficient to specify auxin-mediated development, and emphasizes mechanisms in which auxin serves as a bottleneck for plant morphogenesis, translating common cellular activities into defined developmental readouts.
