Characterization of the final stage in seed abortion in indeterminate soybean, white lupin and pea Inra
Pigeaire, A.; Duthion, C.; Turc, O..
Des travaux japonais déjà anciens ont mis en évidence chez le soja (Glycine max (L.) Merril) un stade limite pour l’avortement des grains. La connaissance de ce stade est utile pour décrire le développement des gousses d’une manière non pas arbitraire mais au contraire significative par rapport à la mise en place des composantes du rendement. Afin de rechercher une caractérisation simple de ce stade, des mesures de longueur et de poids ont d’abord été effectuées sur l’ensemble des grains mûrs et avortés d’échantillons prélevés à la récolte. Vingt échantillons de soja de type indéterminé (10 cultivars), 4 de lupin blanc, Lupinus albus L. (4 cultivars), et 2 de pois, Pisum sativum L. (2 cultivars) ont été analysés. L’absence de chevauchement des...

Co-ordination of cell division and tissue expansion in sunflower, tobacco, and pea leaves: dependence or independence of both processes ? Inra
Granier, C.; Turc, O.; Tardieu, F..
Temporal analyses of cell division and tissue expansion in pea, tobacco, and sunflower leaves reveal that both processes follow similar patterns during leaf development. Relative cell division and relative tissue expansion rates are maximal and constant during early leaf development, but they decline later. In contrast, relative cell expansion rate follows a bell-shaped curve during leaf growth. Cell division and tissue expansion have common responses to temperature, intercepted radiation, and water deficit. As a consequence, final leaf area and cell number remain highly correlated throughout a large range of environmental conditions for these different plant species, indicating that cell division and tissue expansion are co-ordinated during leaf...

Drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected to soil water deficit Inra
Fuad hassan, A.; Tardieu, F.; Turc, O..
The growth and emergence of maize silks has a considerable importance in yield determination under drought conditions. Spatial and temporal patterns of the rates of tissue expansion and of cell division were characterized in silks of plants subjected to different soil water potentials. In all cases, silk development consisted of four phases: (1) cell division and tissue expansion occurred together uniformly all along the silk; (2) cell division progressively ceased from tip to base, while expansion remained spatially uniform including during the phase (3) after the cessation of cell division; and (4) as the silk emerged from the husks, expansion ceased in the emerged portion, probably because of direct evaporative demand, while the relative growth rate...

Floret initiation, tissue expansion and carbon availability at the meristem of the sunflower capitulum as affected by water or light deficits Inra
Dosio, G.A.A.; Tardieu, F.; Turc, O..
The co-ordination between floret initiation and meristem expansion, and their relationships with carbon availability, were studied and quantified in sunflower (Helianthus annuus) plants subjected to light or water shortages.Meristem size, number of floret primordia, primordium size, rate of plant biomass accumulation, leaf area, photosynthetic rate, and soluble sugar content in the capitulum were measured until completion of floret initiation.Although treatments differentially affected tissue expansion and biomass acquisition, a common relationship between the final number of florets and the rate and duration of meristem expansion was conserved. In the absence of water deficit, changes in relative expansion rate in the meristem paralleled changes in...

Modelling temperature-compensated physiological rates, based on the co-ordination of responses to temperature of developmental processes Inra
Parent, B.; Turc, O.; Gibon, Y.; Tardieu, F..
Temperature fluctuates rapidly and affects all developmental and metabolic processes. This often obscures the effects of developmental trends or of other environmental conditions when temperature fluctuates naturally. A method is proposed for modelling temperature-compensated rates, based on the coordination of temperature responses of developmental processes. In a data set comprising 41 experiments in the greenhouse, growth chamber, or the field, the temperature responses in the range of 6-36 degrees C for different processes were compared in three species, maize, rice, and Arabidopsis thaliana. Germination, cell division, expansive growth rate, leaf initiation, and phenology showed coordinated temperature responses and followed common laws within each...

Water deficits uncouple growth from photosynthesis, increase C content, and modify the relationships between C and growth in sink organs Inra
Muller, B.; Pantin, F.; Génard, M.; Turc, O.; Freixes, S.; Piques, M.; Gibon, Y..
In plants, carbon (C) molecules provide building blocks for biomass production, fuel for energy, and exert signalling roles to shape development and metabolism. Accordingly, plant growth is well correlated with light interception and energy conversion through photosynthesis. Because water deficits close stomata and thus reduce C entry, it has been hypothesised that droughted plants are under C starvation and their growth under C limitation. In this review, these points are questioned by combining literature review with experimental and modelling illustrations in various plant organs and species. First, converging evidence is gathered from the literature that water deficit generally increases C concentration in plant organs. The hypothesis is raised that...
