Rande, Hugo. "Effets du niveau de pollution métallique et des stratégies fonctionnelles sur les types d’effets en jeu dans les interactions entre plantes au niveau d’anciens sites miniers des Pyrénées." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0032.
Plant-plant interactions have been overlooked in metal/metalloids-impacted environments and are likely driven by several factors whose influence is barely known. First, plant-plant interactions depend on the level of metal pollution, but also on the functional plant strategies of the interacting plants. Furthermore, plants can have several type of effects on their immediate environment, acting at different timescales. Plants canopy and roots have an instantaneous influence on the microclimate and available resources in their immediate vicinity. Then, during a growing season, the production of litter and its decomposition beneath their canopy can influence soil chemical and physical properties. In the longer term, when this cycle of litter production/decomposition is repeated over the years, the dynamics of the organic matter will influence soil conditions even more. In this thesis, our main objective was to delineate these effects, and to understand how plant functional strategies can influence these various effects along metal pollution gradients. We studied these effects during three consecutive years (from 2020 to 2022) in a former mining valley in the French Pyrenees (Sentein, Ariège, France). In this area, we studied interactions between plants using observational and target transplantation methods controlling for the presence of plant canopy and/or plant litter, in three study sites: a slag heap with homogeneous pollution and two mine tailings areas with heterogeneous pollution creating a gradient of pollution. Along these gradients, short-term canopy and root-uptake effects followed the Stress Gradient Hypothesis, switching from competition to facilitation as pollution increased. This facilitation was stronger when the species producing the effect were acquisitive (in relation with soil resources and the Leaf Economic Spectrum), and benefits more the low metal-tolerant plants. These positive effects were mainly due to the improvement of micro-climatic conditions during hot and dry episodes in summer. Concerning the effects linked to litter production and decomposition, negative effects on target plants were found, suggesting the so-called “elemental allelopathic” effects, in relation with the high concentration of metallic elements in the decomposing litter. These negative litter effects were more important in the least polluted environments, where metal-accumulating metallophyte plants (which have high concentration of metals in their leaves) and less metal-tolerant plants interacts. They were particularly marked for targets sensitive to metal pollution. The results of this thesis give important perspectives regarding the use of facilitation for the phyto-management of metals/metalloids-polluted environments, given that the functional strategies of interacting plants and the level of pollution involved are explicitly considered. Additionnaly, the results obtained during the 2022 heatwave provide useful insights regarding the expected evolution of the different effects driving plant interactions in metalliferous ecosystems in a climate change context

Hairy root, which resulted from T-DNA transformation of Agrobacterium rhizogenes, is widely used in studying root biology. It is also applied in producing diverse plant secondary metabolites due to its fast-growth and metabolite-accumulating abilities. However, the regulatory mechanisms of hairy root initiation, growth, and metabolite accumulation are largely unknown. To expand the applicability of hairy roots, we used Nicotiana tabacum L. var Wisconsin 38, its pathogen A. rhizogenes A4, and its well-known metabolite nicotine as a study model to unveil the mechanisms that regulate hairy root growth and secondary metabolite accumulation. In the part of growth regulation, we focused on four rol genes, including rolA, B, C, and D, which are located on TL-DNA of A. rhizogenes A4. These rol genes are known to participate in rooting; however, the means by which the rol genes contribute to the initiation and the maintenance of hairy roots remain unknown. In this study, we knocked-out these rol genes in A. rhizogenes A4 respectively, and used for inducing hairy roots. We found that A. rhizogenes lacking rolB or rolC induced hairy roots with less rooting ability than wild-type A. rhizogenes, whereas lacking rolA or rolD showed no significant differences. Moreover, tobacco hairy roots lacking either rolB or rolC exhibited fewer branch roots and lost their growth ability after long-term subculture than wild-type-induced hairy roots, whereas lacking of rolA or rolD did not show significant differences. We considered rolB and rolC involved mainly in the regulation of hairy root growth. Our microarray analysis revealed that the expression of several groups of genes encoding lipid transfer proteins (LTP) and reactive oxygen species (ROS)-related genes was significantly suppressed in rolB- or rolC- deficient hairy roots. We also found that hairy root clones that exhibited greater branching also had higher levels of RolB, RolC, and the microarray-identified LTP genes. In addition, we compared the transcriptomic difference between hairy roots and un-infected intact roots by microarray, and the expression levels of the above mentioned LTP-encoding genes were dramatically higher in the hairy root. Moreover, ROS staining showed that ROS level were lower in rolB- or rolC- deficient hairy roots. We therefore suggest that up-regulating LTP and increasing the level of ROS are important for hairy root growth. In the part of secondary metabolite regulation, we found that tobacco hairy roots accumulate much more nicotine than the intact roots, and the nicotine contents were positively correlated with the amount of another metabolite anabasine, indicating hairy roots had higher secondary metabolic flux. By real-time PCR analysis, hairy roots had more abundant expression of genes encoding enzymes in nicotine biosynthetic pathway and storage transporters, indicating the accumulation of nicotine in hairy roots is via transcriptional regulation. Moreover, hairy roots with a higher growth rate had greater nicotine content, suggesting that growth and nicotine production are regulated synchronically. Nicotine up-regulation in hairy roots was regulated by ethylene response factor (ERF)189 and ERF199 to activate the key enzymes putrescine N-methyltransferase and N-methylputrescine oxidase with a jasmonic acid (JA)-independent signal. However, the possible regulator has not been identified. These findings indicate high secondary metabolites accumulated hairy root clones can be simply selected by measuring their growth rate, which expand the hairy root researches and applications in secondary metabolites.
