Gravisensitivity and automorphogenesis of lentil seedling roots grown on board the International Space Station 189
Driss-Ecole, D; Legué, V.; Carnero-Diaz, E; Perbal, G.
The GRAVI-1 experimentwas brought on board the International Space Station by Discovery (December 2006) and carried out in January 2007 in the European Modular Cultivation System facility. For the first run of this experiment, lentil seedlings were hydrated and grown in microgravity for 15 h and then subjected for 13 h 40 min to centrifugal accelerations ranging from 0.29 _ 1022 g to 0.99 _ 1022 g. During the second run, seedlings were grown either for 30 h 30 min in microgravity (this sample was the control) or for 21 h 30 min and then subjected to centrifugal accelerations ranging from 1.2 _ 1022 g to 2.0 _ 1022 g for 9 h. In both cases, root orientation and root curvature were followed by time-lapse photography. Still images were downlinked in near real...

Morphogenetic analysis of the phenotypic variability of the architectural unit of Hydrangea macrophylla 189
Galopin, G.; Mauget, J.C.; Morel-Chevillet, P..
Hydrangea macrophylla is a ligneous plant that has attracted he attention of many plant breeders and agronomists for the purpose of enhancing its phenotypic plasticity. However, this plasticity was always exploited empirically. Can this plasticity be assessed by a more scientific approach? In this work, the phenotypic variation is analysed via a description of the different development sequences of the plant and by exposing the plant to different contrasted environments. The architectural unit consists of two morphogenetic units: the Vegetative Unit (VU) and the Vegetative and Floral Unit (VFU). They result in four successive development sequences: an organogenetic phase accompanied by continuous growth (sequence A), floral transformation (sequence B),...

Simulations of virtual plants reveal a role for SERRATE in the response of leaf development to light in Arabidopsis thaliana 189
Chenu, K.; Franck, N.; Lecoeur, J..
#The SERRATE gene (SE) was shown to determine leaf organogenesis and morphogenesis patterning in Arabidopsis thaliana. The se-1 mutant was used here to investigate the role of SE in leaf development in response to incident light. Virtual plants were modelled to analyse the phenotypes induced by this mutation.# •Plants were grown under various levels of incident light. The amount of light absorbed by the plant was estimated by combining detailed characterizations of the radiative environment and virtual plant simulations.# •Four major changes in leaf development were induced by the se-1 mutation. Two constitutive leaf growth variables were modified, with a lower initial expansion rate and a higher duration of expansion. Two original responses to a reduced...
