Journal ArticleDOI
Functional Genomic Analysis of the AUXIN RESPONSE FACTOR Gene Family Members in Arabidopsis thaliana : Unique and Overlapping Functions of ARF7 and ARF19
Yoko Okushima,Paul J. Overvoorde,Kazunari Arima,Jose M. Alonso,April Chan,Charlie Chang,Joseph R. Ecker,Beth Hughes,Amy Lui,Diana Nguyen,Courtney Onodera,Hong Quach,Alison M. Smith,Guixia Yu,Athanasios Theologis +14 more
TL;DR: The identification and characterization of T-DNA insertion lines for 18 of the 23 ARF gene family members in Arabidopsis thaliana suggest that the ARF7 and ARF19 proteins play essential roles in auxin-mediated plant development by regulating both unique and partially overlapping sets of target genes.
Journal ArticleDOI
Auxin Control of Root Development
TL;DR: The role of identified molecular components that convert auxin gradients into local differentiation events, which ultimately defines the root architecture is reviewed, in order to understand how this class of hormones participates in the control of root development.
Journal ArticleDOI
A novel aux/IAA28 signaling cascade activates GATA23-dependent specification of lateral root founder cell identity.

TL;DR: The first molecular components that control lateral root founder cell identity in the Arabidopsis root are identified, including an IAA28-dependent auxin signaling module in the basal meristem region that regulates GATA23 expression and thereby lateral rootfounder cell specification and root branching patterns.
Journal ArticleDOI
SAUR Inhibition of PP2C-D Phosphatases Activates Plasma Membrane H+-ATPases to Promote Cell Expansion in Arabidopsis
Angela K. Spartz,Hong Ren,Mee Yeon Park,Kristin N. Grandt,Sang Ho Lee,Angus S. Murphy,Michael R. Sussman,Paul J. Overvoorde,William M. Gray +8 more
TL;DR: In this article, the authors demonstrate that SAUR proteins provide a mechanistic link between auxin and plasma membrane H+-ATPases in Arabidopsis thaliana.
Journal ArticleDOI
Functional genomic analysis of the AUXIN/INDOLE-3-ACETIC ACID gene family members in Arabidopsis thaliana
Paul J. Overvoorde,Yoko Okushima,Jose M. Alonso,April Chan,Charlie Chang,Joseph R. Ecker,Beth Hughes,Amy Liu,Courtney Onodera,Hong Quach,Alison M. Smith,Guixia Yu,Athanasios Theologis +12 more
TL;DR: The data suggest extensive functional redundancy among Aux/IAA gene family members and that enhanced stability of the AXR3/IAa17 protein severely alters the molecular phenotype, resulting in developmental defects.
