Highlights
?Auxin responsive proteins in Arabidopsis roots were identified from 3,514 detected proteins.
?All six auxin receptors are stable in response to hormone via novel MRM assays.
?The >100 differentially expressed proteins exhibit dynamic and transient responses to auxin.
?Phenotypic screening of the top responsive proteins uncovered several novel root mutants.
