The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

Adult Drosophila exposed to auxin at the recommended concentrations for the AGES transgene expression system display defects in feeding behavior, have altered metabolic transcripts, and have reduced triacylglyceride levels.

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

Auxin-inducible degradation of CRISPR-tagged endogenous proteins in mice reveals cell-type-specific dependence on the mitotic chromosome condensation proteins.

Two protein kinases are required to activate auxin efflux transporters from plants.

Vacuolar morphologenesis correlates with cell size and is required for auxin-dependent inhibition of growth.

GNOM controls both auxin transport and auxin signaling to coordinate tissue cell polarity during vein patterning in plants.

The auxin-sensitive Aux/IAA transcriptional repressors regulate approximately 35% of the annotated genes in Physcomitrella patens and exhibit complex interactions with both the activating and repressing ARF transcription factors.

Auxin binding to the ETTIN transcription factor disrupts the interaction between ETT and a TPL/TPR co-repressor and subsequently affects chromatin dynamics to ensure proper gynoecium development.

Auxin is produced in the endosperm after fertilization and drives the development of the seed coat in Arabidopsis.
