Journal ArticleDOI
Identification of an SCF ubiquitin–ligase complex required for auxin response in Arabidopsis thaliana
William M. Gray,William M. Gray,J. Carlos del Pozo,J. Carlos del Pozo,Loni Walker,Lawrence Hobbie,Lawrence Hobbie,Eddy Risseeuw,Travis W. Banks,William L. Crosby,Ming Yang,Hong Ma,Mark Estelle,Mark Estelle +13 more
TL;DR: In Arabidopsis, auxin response is dependent on a ubiquitin-ligase (E3) complex called SCFTIR1, which provides new support for a model in which auxin action depends on the regulated proteolysis of repressor proteins.
Journal ArticleDOI
AXR2 Encodes a Member of the Aux/IAA Protein Family
Punita Nagpal,Loni Walker,Jeffrey C. Young,Ami Sonawala,Candace Timpte,Mark Estelle,Jason W. Reed +6 more
TL;DR: Functional differences among members of the Arabidopsis IAA gene family are illustrated, with activation of AXR2/IAA7 is sufficient to induce morphological responses normally elicited by light.
Journal ArticleDOI
AXR1-ECR1–Dependent Conjugation of RUB1 to the Arabidopsis Cullin AtCUL1 Is Required for Auxin Response
Juan Carlos del Pozo,Sunethra Dharmasiri,Hanjo Hellmann,Loni Walker,William M. Gray,Mark Estelle +5 more
TL;DR: It is demonstrated that the formation of RUB-AtCUL1 is dependent on AXR1 and ECR1 in vivo, and this results provide strong support for a model in which RUB conjugation of AtCul1 affects the function of SCF E3s that are required for auxin response.
Journal ArticleDOI
Molecular mechanisms of auxin action.
Loni Walker,Mark Estelle +1 more
TL;DR: Identification of transcription factors, some with defined genetic function, has shed new light on the mechanisms of auxin regulated gene expression and indicates that regulated protein degradation by the ubiquitin-proteosome pathway has an important function in auxin action.
