EIN3-Dependent Regulation of Plant Ethylene Hormone Signaling by Two Arabidopsis F Box Proteins: EBF1 and EBF2
Thomas Potuschak,Esther Lechner,Yves Parmentier,Shuichi Yanagisawa,Sandrine Grava,Csaba Koncz,Pascal Genschik +6 more
TL;DR: This work places two Arabidopsis F box proteins called EBF1 and EBF2 within the genetic framework of the ethylene-response pathway and supports a model in which ethylene action depends on EIN3 protein stabilization.

F-box proteins everywhere
TL;DR: Nearly 700 F-box proteins have been predicted in Arabidopsis, suggesting that plants have the capacity to assemble a multitude of SCF complexes, possibly controlling the stability of hundreds of substrates involved in a plethora of biological processes.

Arabidopsis TCP20 links regulation of growth and cell division control pathways.
TL;DR: A model in which organ growth rates, and possibly shape in aerial organs, are regulated by the balance of positively and negatively acting teosinte-branched, cycloidea, PCNA factor (TCP) genes in the distal meristem boundary zone where cells become mitotically quiescent before expansion and differentiation is proposed.

Interaction between the bHLH Transcription Factor FIT and ETHYLENE INSENSITIVE3/ETHYLENE INSENSITIVE3-LIKE1 Reveals Molecular Linkage between the Regulation of Iron Acquisition and Ethylene Signaling in Arabidopsis
Sivasenkar Lingam,Julia Mohrbacher,Tzvetina Brumbarova,Thomas Potuschak,Claudia Fink-Straube,Eddy Blondet,Pascal Genschik,Petra Bauer +7 more
TL;DR: It is proposed that upon ethylene signaling, FIT is less susceptible to proteasomal degradation, presumably due to a physical interaction between FIT and EIN3/EIL1, one of the signals that triggers Fe deficiency responses at the transcriptional and posttranscriptional levels.
The exoribonuclease XRN4 is a component of the ethylene response pathway in Arabidopsis.
Thomas Potuschak,Amérin Vansiri,Brad M. Binder,Esther Lechner,Richard D. Vierstra,Pascal Genschik +5 more
TL;DR: The identification of XRN4 as an integral new component in ethylene signaling adds RNA degradation as another posttranscriptional process that modulates the perception of this plant hormone.
