Full textThe first plant cell culture has been developed by Gautheret in 1939 based on carrot plant cell tissus. He obtained these results through the discovery of the plant totipotency power (Haberland, 1902). He used for cal production a culture medium composed by macroelements (K, N, P…) and microelements (Mg, B …), vitamin, sugar. Later on, several mediums were used like and described in literature i.e. Murashige and Skoog (1962), White (1934) or Gamborg, Miller and Ojima (1970). The differences between such medium consisted mainly concentrations especially of phosphates, nitrates or auxin/cytokinine balance. However, each species needs specific medium for growth. Any people works of this subject and the interest for pharmaceutical and cosmetical industry grow up. Plant cell culture is a difficult technology an industrial use. Recently, two companies performed industrial production of taxol (Taxus baccata) and shikonin (Lithospernum erythrorizon) respectively PhytonBitotech and Mitsui petrochemical. My thesis work was to develop plant cell cultures fom unusual plants which can be used for the industrial production of cosmetics

Full textStilbenes are phenolic compounds produced by different plant species. The most well known stilbene is the trans-resveratrol (trans-3-5-4’ trihydroxystilbene) which acts as a phytoalexine on grapevine. Its discovery inside red wine led to enlighten its biological activities on human health. So the resveratrol became an interesting and hopeful molecule in medicine and also for understanding grapevine defenses but the biosynthetic mechanisms of this compound stayed unclear. Along this work, we used a Vitis 41B cell suspensions obtained from calli. In a first time, the cell growth kinetic was determined and we evaluated its ability to produced resveratrol. In order to study parameters which led to the resveratrol synthesis, we have tested various inducers and a concentration of 0,2 mM methyljasmonate showed the best induction. A scale-up in a 2-L bioreactor was conducted and led to the purification and identification of viniferins and allowed to obtain a 200 mg/L resveratrol accumulation. These results seem indicate that the viniferin production is linked to the metabolisation of the resveratrol inside the culture medium. The second part of this work focussed on the early synthesis of the resveratrol at the cellular scale. We have used videomicroscopy and confocal microscopy in order to show that the resveratrol synthesis takes place inside the cytosol and that its excretion is localized. Our study clearly showed that the grapevine cell suspension represents a pertinent and powerful system to study the resveratrol biosynthesis and its bioproduction

Full textHabituation is known as a common character of in vitro plant cells. This phenomenon can be considered as a genral tendancy of plant cells to loose their exogenous hormonal requirement. Habituation is often correlated with lack of the synthesis and production of secondary metabolites. In this work we attempted to identify genes which were newly expressed or repressed during the transition from the normal to the habituated state. Our aim was to elucidate some biochemical aspects associated with hormonal autotrophy of plant cells. We compared the protein patterns of a 2,4 D dependant line to those of a 2,4 D independent cell line selected from the previous one. We had two major objectives : detect the polypeptides related to the habituated state ; compare changes in their expression patterns under a defined hormonal treatment, ie cytokinin or auxin supply in the culture medium. In the course of this study, 3 polypeptides with 28, 17 and 16kDa molecular mass were detected. Their synthesis appeared to be correlated with indole alkaloid accumulation in the 2,4 D dependent cell line. On the other hand a 53kDa polypeptide was always expressed at high level in habituated cell line, while a group of 5 polypeptides inluding polypeptide s was either completely lacking or at least not regulated by cytokinins in the habituated cell line. Abundance of th e 53kDa polypeptide and the attenuated expression of the polypeptide s 28kDa can be considered as the main traits of all habituated suspension cell lines of Catharanthus roseus. Differences in protein patterns were more important in membrane extracts. We found that microsomal protein profiles were relatively more differents between the two cell lines with a 16kDa polypeptide m1 expressed intensively in habituated cells. Cytokinins and auxins can modify the expression pattern, and in case of this peculiar regulation, the polypeptide m1 was purified and the corresponding sequence was determined. The oligonucleotides probes constructed from the N-terminal sequence were used for screening a cDNA library from Catharanthus roseus mRNA poly(A). Six specific clones were isolated. Elucidation of m1 gene function could perhaps bring new information about the hormonal autotrophy mechanism in Catharanthus roseus cell lines ?
