Changes in SWEET-mediated sugar partitioning affect photosynthesis performance and plant response to drought

E. Aubry, G. Clement, E. Gilbault, S. Dinant, R. LE HIR

This study shows that disrupting SWEET sugar transporters in Arabidopsis affects photosynthesis and drought response by altering sugar partitioning, not total sugar content.

Carbohydrate distribution via SWEET17 is critical for Arabidopsis inflorescence branching under drought

M. Valifard, A. Khan, R. LE HIR, B. Pommerrenig, H. E. Neuhaus, I. Keller

The paper identifies SWEET17's role in carbohydrate distribution to support inflorescence branching under drought stress in Arabidopsis.

SUC2 sucrose transporter is required for leaf apoplasmic sucrose levels. Consequences for phloem loading strategies

F. Vilaine, L. Bill, R. Le Hir, C. Bellini, S. Dinant

This study investigates the role of SUC2 in apoplasmic sucrose levels and its impact on phloem loading strategies in Arabidopsis, revealing its influence on foliar carbohydrate storage and interactions with symplasmic pathways.

Impairment of sugar transport in the vascular system acts on nitrogen remobilisation and nitrogen use efficiency in Arabidopsis.

B. Hoffmann, E. Aubry, A. Marmagne, S. Dinant, F. Chardon, R. Le Hir

This study shows that disrupting SWEET11 and SWEET12 sugar transporters in Arabidopsis impairs stem development but improves nitrogen use efficiency and remobilization to seeds.

A vacuolar hexose transport is required for xylem development in the inflorescence stem of Arabidopsis.

E. Aubry, B. Hoffmann, F. Vilaine, F. Gilard, P. A. W. Klemens, F. Guerard, B. Gakiere, H. E. Neuhaus, C. Bellini, S. Dinant, R. Le Hir

This study shows that SWEET16-mediated hexose transport at the tonoplast is essential for xylem cell division and secondary cell wall formation in Arabidopsis inflorescence stems.

Molecular framework for TIR1/AFB-Aux/IAA-dependent auxin sensing controlling adventitious rooting in Arabidopsis

A. Lakehal, S. Chaabouni, E. Cavel, R. Le Hir, A. Ranjan, Z. Raneshan, O. Novak, D. I. Pacurar, I. Perrone, F. Jobert, L. Gutierrez, L. Bako, C. Bellini

The paper identifies TIR1 and AFB2 as positive regulators and IAA6, IAA9, and IAA17 as negative regulators of adventitious root formation in Arabidopsis, revealing their role in modulating jasmonate homeostasis.

Synchrotron FTIR and Raman spectroscopy provide unique spectral fingerprints for Arabidopsis floral stem vascular tissues

S. Dinant, N. Wolff, F. De Marco, F. Vilaine, L. Gissot, E. Aubry, C. Sandt, C. Bellini, R. Le Hir

The paper uses synchrotron FTIR and Raman spectroscopy to analyze cell wall composition in Arabidopsis floral stem vascular tissues, showing that SWEET gene disruption affects phloem and xylem cell walls differently.
