The plant architecture is regarded as an important trait for breeding the yield of crop plants, the managements of disease and the visual quality of ornamental plants.

The scientific program of Arch-E team aims to understand how environmental cues, especially light, modulates bud burst and branching pattern, two fundamental processes of plant architecture. This work is carried out on rose bush. The scientific program consists of four axes:

1)  Analysis and identification of the key architectural components of the shape of the adult plant;

2)  Identification of the relationships between light and some physiological variables of the whole plant;

3)  Molecular control of bud burst and shoot growth by light;

4)  Structural-functional 3D modelling of bud burst in rose bush, at the whole plant scale.
