Hierarchical global and local auxin signals coordinate cellular interdigitation in Arabidopsis

The paper shows auxin signaling coordinates cell shape in Arabidopsis through global and local pathways involving TIR1/AFB and TMK.

Comparative mutant analyses reveal a novel mechanism of ARF regulation in land plants

The paper identifies a conserved mechanism regulating class-B ARF protein levels in land plants through comparative mutant analysis in maize and moss.

The AFB1 auxin receptor controls the cytoplasmic auxin response pathway in Arabidopsis thaliana

This study identifies the N-terminal region of AFB1 as critical for its specific role in the rapid auxin response pathway in Arabidopsis thaliana, including calcium influx and root growth inhibition.

A Clade-D Auxin Response Factor is a Major Regulator of Auxin Signaling in Physcomitrium patens.

This study identifies clade-D ARFs as transcriptional activators in Physcomitrium patens, showing they regulate development and interact with activating ARFs to enhance gene expression.

Heterologous expression of a lycophyte protein enhances angiosperm seedling vigor

The paper shows that expressing a lycophyte BRX protein in Arabidopsis enhances seedling vigor by increasing seed and embryo size.

Dual role of auxin in regulating plant defense and bacterial virulence gene expression during Pseudomonas syringae PtoDC3000 pathogenesis.

This study shows auxin promotes PtoDC3000 pathogenesis by suppressing host defenses and directly regulating bacterial virulence gene expression.

Genetic analysis of the Arabidopsis TIR1/AFB auxin receptors reveals both overlapping and specialized functions

The paper genetically analyzes Arabidopsis TIR1/AFB auxin receptors, showing functional overlap except for AFB1, which has a specialized role in root growth inhibition and gravitropism.

Auxin-sensitive Aux/IAA proteins mediate drought tolerance in Arabidopsis by regulating glucosinolate levels

The paper shows that Aux/IAA proteins regulate glucosinolate levels, which in turn affect drought tolerance in Arabidopsis by influencing stomatal regulation.

The Ca2+ sensor protein CMI1 fine tunes root development, auxin distribution and responses

This study identifies CMI1 as a Ca2+ sensor that modulates auxin signaling and root development in Arabidopsis by repressing early auxin responses.

Selective auxin agonists induce specific AUX/IAA protein degradation to modulate plant development

The paper identifies selective auxin agonists that induce specific AUX/IAA protein degradation, revealing their role in modulating plant development through targeted chromatin remodeling.
