Abstract
BACKGROUND The production of secondary metabolites through the culture of entire plants is of great interest. Soilless culture, such as hydroponics, enables the control of plant growth and metabolism. Specific environmental conditions must be developed to maximize the productivity of medicinal plants used as efficient natural bioreactors. METHODS The nutrient solution of newly established hydroponic cultures ofDatura innoxia Mill. were inoculated with Agrobacterium rhizogenes (A.r.) wild strains (TR7, TR107, 11325 or 15834). Growth and the alkaloid contents of roots and aerial parts were analyzed. Axenic cultures were also performed with modified TR7 strains containing the egfp or gus reporter gene. In vitro isolated root cultures enabled the phenological and molecular demonstration of gene transfer. RESULTS A.r.TR 7 led to a greater improvement in plant secondary metabolism and growth. Positive expression of the reporter genes occurred. Isolation and subculture of some of the roots of these plants showed a hairy root phenotype; molecular tests proved the transfer of bacterial genes into the roots isolated from the plants. CONCLUSIONS Hyoscyamine and scopolamine productivity is enhanced after A.r. inoculation in the nutrient solution of hydroponic plants. Transformation events occur in the original roots of the plants. This leads to chimeric plants with a part of their roots harboring a hairy root phenotype. Such semi-composite plants could be used for successful specialized metabolite bioproduction in greenhouses.

Abstract
The circadian clock is an endogenous system that allows organisms to daily adapt and optimize their physiology and metabolism. We studied the key circadian clock gene (CCG) orthologs in Nicotiana tabacum seedlings and in hairy root cultures (HRC). Putative genes involved in the metabolism of xenobiotic compounds (MXC) were selected and their expression profiles were also analyzed. Seedlings and HRC displayed similar diurnal variations in the expression profiles for the CCG examined under control conditions (CC). MXC-related genes also showed daily fluctuations with specific peaks of expression. However, when HRC were under phenol treatment (PT), the expression patterns of the clock and MXC-related genes were significantly affected. In 2-week-old HRC, PT downregulated the expression of NtLHY, NtTOC1, and NtPRR9 while NtFKF1 and NtGI genes were upregulated by phenol. In 3-week-old HRC, PT also downregulated the expression of all CCG analyzed and NtTOC1 was the most affected. Following PT, the expression of the MXC-related genes was upregulated or displayed an anti-phasic expression profile compared to the expression under CC. Our studies thus provide a glimpse of the circadian expression of clock genes in tobacco and the use of HRC as a convenient system to study plant responses to xenobiotic stresses.

Abstract
This article proposes a feeding strategy based on a kinetic model to enhance hairy roots growth. A new approach for modeling hairy root growth is used, considering that there is no nutrient limitation thanks to an appropriate feeding, and the intracellular pools are supposed to be always saturated. Thus, the model describes the specific growth rate from extracellular concentration of the major nutrients and nutrient uptakes depend on biomass growth. An optimized feeding strategy was determined thanks to the model to maintain the major nutrient levels at their optimum assuming optimal initial concentrations. The optimal feed rate is computed in open loop using kinetic model prediction or in closed loop using conductivity measurements to estimate biomass growth. Datura innoxia was chosen as the model culture system. Shake flask cultures were used to calibrate the model. Finally, cultures in bioreactor were performed to validate the model and the control laws.

Abstract
INTRODUCTION Hydroponics has been shown as a possible way to produce high quality plant biomass with improved phytochemical levels. Nevertheless, effects of plant biotic and abiotic environment can lead to drastic changes and plant growth conditions must be optimised. OBJECTIVE To evaluate how much microbes and Agrobacterium rhizogenes TR7 wild strain may affect the tropane alkaloid profile in Datura innoxia Mill. plants cultivated in hydroponic conditions. METHODOLOGY Datura innoxia Mill. plants were cultivated in hydroponic with sterile or non-sterile conditions. For half of the non-sterile plants, Agrobacterium rhizogenes TR7 strain was added to the nutrient solution for hydroponics. The tropane alkaloid content of leaves and roots was analysed by UFLC/ESI-HRMS and MS/MS. The metabolite profiles were compared using partial least square-discriminant analysis. RESULTS In sterile conditions, aerial parts contained more scopolamine than the roots. However, the diversity of tropane alkaloids was greater in roots. Furthermore, 21 known compounds and four non-elucidated tropane alkaloids were found. The tropane alkaloid profile was shown to be statistically different between sterile and non-sterile hydroponic conditions. The levels of 3-acetoxy-6-hydroxytropane and 3-hydroxylittorine were higher in plants inoculated with A. rhizogenes. Five other tropane compounds were found in higher amounts in non-axenic control plants. Hyoscyamine and scopolamine total contents were much higher in the whole plant co-cultivated with A. rhizogenes TR7 than in controls. Furthermore, the leaves and roots of axenic plants contained more alkaloids than non-sterile ones. CONCLUSION In hydroponic conditions, microbes induced variations of the phytochemical levels. Addition of A. rhizogenes TR7 into the nutrient solutions improved the total hyoscyamine and scopolamine production.
