The transcription factor bZIP11 acts antagonistically with trehalose 6-phosphate to inhibit shoot branching

A. Hellens, P. Kreisz, J. L. Humphreys, R. Feil, J. E. Lunn, W. Droge-Laser, C. A. Beveridge, F. Fichtner, C. Weiste, F. F. Barbier

The paper identifies bZIP11 as a transcription factor that inhibits shoot branching in Arabidopsis by acting antagonistically with trehalose 6-phosphate.

Transcription factor HSFA7b controls ethylene signaling and meristem maintenance at the shoot apical meristem during thermomemory

S. John, F. Apelt, A. Kumar, D. Bents, M. G. Annunziata, F. Fichtner, B. Mueller-Roeber, J. J. Olas

This study identifies HSFA7b as a transcription factor that regulates ethylene signaling and SAM maintenance during thermomemory in Arabidopsis.

Auxin-independent effects of apical dominance induce temporal changes in phytohormones

D. Cao, F. Barbier, E. A. Dun, F. Fichtner, L. Dong, S. C. Kerr, C. A. Beveridge

This study investigates the role of auxin and other phytohormones in apical dominance, showing that auxin's effects on cytokinins are significant after bud release, while strigolactones have limited impact on initial bud outgrowth.

Different plasticity of bud outgrowth at cauline and rosette nodes in Arabidopsis thaliana

F. Fichtner, F. F. Barbier, S. C. Kerr, C. Dudley, P. Cubas, C. Turnbull, P. B. Brewer, C. A. Beveridge

The paper reveals different plasticity in branching at cauline and rosette nodes in Arabidopsis through correlative analyses under varied genetic and environmental contexts.

Blocking plasmodesmata in specific phloem cell types reduces axillary bud growth in Arabidopsis thaliana

A. Paterlini, D. Dorussen, F. Fichtner, M. van Rongen, R. Delacruz, A. Vojnovic, Y. Helariutta, O. Leyser

The paper shows that blocking plasmodesmata in phloem cells of Arabidopsis reduces axillary bud growth rates without affecting bud activation.

Sucrose promotes D53 accumulation and tillering in rice

S. B. Patil, F. F. Barbier, J. Zhao, S. A. Zafar, M. Uzair, Y. Sun, J. Fang, J. Bertheloot, S. Sakr, F. Fichtner, T. G. Chabikwa, S. Yuan, C. A. A. Beveridge, X. Li

This study shows that sucrose promotes tillering in rice by inhibiting strigolactone (SL) signaling, specifically by suppressing D3 and D14, which are key components of SL perception and D53 degradation.
