ProteomicsVariation in auxin sensing guides AUX/IAA repressor ubiquitylation and destruction
Auxin is a drug-like small molecule and morphogen that triggers the formation of SCFTIR1/AFB-AUX/IAA co-receptor complexes leading to ubiquitylation and proteasome-dependent degradation of AUX/IAA transcriptional repressors in plants. Here, we systematically dissect auxin sensing by SCFTIR1-IAA6 and...

ProteomicsDegron flexibility enforces auxin sensing
Cullin RING-type E3 ubiquitin ligase SCFTIR1/AFB1-5 and their ubiquitylation targets, AUX/IAAs, sense auxin concentrations in the nucleus. TIR1 binds a surface- exposed degron in AUX/IAAs promoting their ubiquitylation and rapid auxin-regulated proteasomal degradation. Here, we resolved TIR1·auxin·I...

TranscriptomicsGenome-wide analysis of the auxin/indoleacetic acid (Aux/IAA) gene family in allotetraploid rapeseed (Brassica napus L.)
Background: Auxin/Indoleacetic acid (Aux/IAA) genes participate in the auxin signaling pathway and play key roles in plant growth and development. Although the Aux/IAA gene family has been identified in many plants, within allotetraploid Brassica napus little is known. Results: In this study, a tota...

ProteomicsThe small signalling peptide CEP5 attenuates the dynamic AUX/IAA equilibrium
Root architecture is vital for plant growth and largely depends on primary root growth and lateral root development. Several plant hormones have been shown to affect root architecture among which auxin has been granted a central role. Lately, small signalling peptides also emerged as potential molec...
