Sucrose-responsive osmoregulation of plant cell size by a long non-coding RNA

J. Hajny, T. Travnickova, R. M. I. K. Rony, S. Sacharowski, M. Krzyszton, D. Zalabak, C. Hardtke, A. Pecinka, S. Swiezewski, J. M. Van Norman, O. Novak

The paper identifies CARMA as a long non-coding RNA that regulates CANAR expression in the phloem to control cell size and vascular tissue formation in response to sugar and osmotic stress.

ABP1/ABL3-TMK1 cell-surface auxin signaling directly targets PIN2-mediated auxin fluxes for root gravitropism

L. Rodriguez, L. Fiedler, M. Zou, C. Giannini, A. Monzer, D. Vladimirtsev, M. Randuch, Y. Yu, Z. Gelova, I. Verstraeten, J. Hajny, M. Chen, S. Tan, L. Hoermayer, L. Li, , J. Friml

The paper identifies a mechanism where auxin signaling via ABP1-TMK1 receptor module stabilizes PIN2 to reinforce asymmetric auxin flow for root gravitropism.

Decoy Receptor Fine-tunes Cytokinin Signaling

M. Kralova, I. Kubalova, J. Hajny, K. Kubiasova, M. Gallei, H. Semeradova, O. Novak, E. Benkova, Y. Ikeda, D. Zalabak

The paper identifies a decoy receptor in plants that attenuates cytokinin signaling by binding the hormone without activating downstream pathways.

Rapid auxin-mediated phosphorylation of Myosin regulates trafficking and polarity in Arabidopsis

H. Han, I. Verstraeten, M. Roosjen, E. Mazur, N. Rydza, J. Hajny, K. Ötvös, D. Weijers, J. Friml

The paper identifies a rapid auxin-mediated phosphorylation of Myosin XI and MadB2 that regulates PIN transporter trafficking and polarity in Arabidopsis, revealing a non-canonical auxin response mechanism.

PXC2, a polarized receptor kinase, functions to repress ground tissue cell divisions and restrict stele size

J. Goff, R. M. I. K. Rony, Z. Ge, J. Hajny, C. Rodriguez-Furlan, J. Friml, J. M. Van Norman

This study shows that PXC2, a polarized receptor kinase in Arabidopsis, redundantly represses endodermal cell divisions and stele expansion with IRK, and may influence auxin transport.
