Low macroelement availability in most cultivated soils severely limits crop yields in the absence of fertilization. A better understanding of the adaptation of root systems to nutrient-poor soils, and the exploitation of existing genetic diversity in this field, between species and/or varieties, are likely to contribute to the development of new cultivars and new agronomic practices allowing to limit costly and environmentally polluting chemical fertilization inputs. The architecture of the root system and the production of root hairs at the root-soil interface are major determinants of the capacity of the root system to explore the soil and take up nutrient ions. To date, no methodology has been available to phenotype root hairs in a root system considered entirely. In this thesis, I developed a methodology for global, integrative phenotyping of root systems, including root hairs. An original rhizobox-type device was developed, allowing to acquire high resolution images, for which I developed a computerized analysis procedure associating the free software Ilastik for image segmentation, and the softwares WinRHIZOTM and ImageJ for the analysis of global traits characterizing the root development. After validation of the methodology, the root systems of two wheat genotypes, a cultivated emmer wheat cultivar (T.t. dicoccum, cv Escandia), ancestor of durum wheat, and a landrace of durum wheat (T.t. durum, cv Oued Zenati) were compared with each other and with respect to their response to low phosphate (P), nitrogen (N) or potassium (K) availability. In 15-day-old seedlings (roots ca. 30 cm long), N, P or K deficiencies differentially affected plant growth (biomass allocation between roots and leaves, and preferential development of the root system). All three deficiencies were found to result in an increase in the total surface area of the root system, resulting primarily from an increase in the total surface area of root hairs over the entire root system (reflecting an increase in the density and/or length of hairs over the entire system). The rate of increase in total absorptive root hair area was variable between the two varieties and among limiting elements, stronger under N deficiency conditions in the emmer wheat, and P deficiency in the landrace. All the root responses analyzed, including or not the root hairs, revealed a greater developmental plasticity in response to nutrient deficiency in the ancestral variety. A perspective opened by this work would be to compare this plasticity in different wheat varieties recapitulating the domestication and improvement of this species. I also show that the methodology I have developed can be used to phenotype root responses to biotic conditions (presence of Plant Growth Promoting Rhizobacteria)

Symbiosis between legumes and rhizobia is of major importance in terrestrial ecosystems due to its ability to fix atmospheric nitrogen. The molecular dialogue between the two partners, which ultimately leads to development of nodules hosting the N2 fixing bacteria, can be initiated by the binding of Nod factors (NF) secreted by the rhizobial partner on NF receptors at the legume root hair plasma membrane (PM). This triggers a Ca2+ influx through the PM, followed by a cascade of ionic signaling events, involving changes in H+, K+, and Cl- fluxes at the PM. My objective was to characterize molecular mechanisms underlying these early ionic signaling events in the legume model Medicago truncatula. By using the patch-clamp technique on protoplasts obtained either by cell wall enzymatic digestion or laser-assisted ablation from growing root hairs, I have contributed to characterize several ion conductances from this cell type. I especially focused on a cationic conductance activated by membrane hyperpolarization (HACC), uniquely found to be most permeable to Ca2+. This conductance was quickly activated (within less than 1 minute) following NF addition at physiological concentration. Its activation was dependent on the presence of functional NFP (“Nod Factor Perception”) receptors, which suggested that this conductance mediates the early Ca2+ influx triggered by NF perception. In addition, cationic transport systems expressed in M. truncatula root hairs and belonging to the HKT and Glutamate receptor-like (GLR) families were investigated as potential contributors to the early ionic signaling events. Loss-of-function mutant analysis for 3 highly expressed GLRs suggested that these genes did not play major roles in the expression/activity of the HACC conductance, and were not indispensable for nodulation. On the other hand, the HKT transporters, which were found to be Na+-selective, were expressed in nodules, which suggested a role in symbiosis
Mueller, Margarete. "Arabidopsis root hair development in adaptation to iron and phosphate supply." Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2007. http://dx.doi.org/10.18452/15672.
Limitation of immobile nutrients, such as iron (Fe) and phosphate (P), induces the development of additional root hairs that lead to an increase of the absorptive surface of the root. The increased root hair frequency of Fe- and P-deficient Arabidopsis was realized by different strategies. Phosphate-deficient plants increased the number of root hairs while in Festarved plants root hairs were branched. The Fe and P starvation responses in plants are thought to be regulated by a systemic signaling mechanism that communicates the nutrient status of the shoot to the root and by a local signaling mechanism that perceives the Fe or P availability in the soil. The influence of local and systemic signals on the respective root hair phenotype was investigated in split-root experiments. This treatment was combined with either a nutrient-sufficient or -deficient shoot. The root hair branching typical of Fe-deficient plants only occured in the presence of both a local and a systemic Fe-deficiency signal. As a consequence, an Fe sufficiency signal acted dominantly to any deficiency signal, independent of its origin. The increased number of root hairs in P-deficient plants, conversely, was activated through either a local or a systemic P deficiency signal. Thus, the P deficiency signal acted dominantly to any sufficiency signal. To determine, which stage of root hair development was influenced by iron and phosphate, mutants with defects in different stages of root hair development were investigated for their root hair phenotype. Mutants affected in the early stages of root hair development, such as specification, displayed marked changes in the number and localization of root hairs. However, the nutritional signal was perceived and translated in this group of mutants. This indicates that the specification genes are involved in the nutrient-sensitive root hair formation, but may not be the direct targets. Early cell characteristics of root hairs in the late meristematic region of the root, like the expression of marker genes, were unaltered in plants adapted to Fe or P deficiency. This suggested the nutritional signal modulates root hair development after these characteristics have been established. Mutants with defects in the later stages of root hair development, such as root hair elongation, showed short or deformed root hairs in the proper position and frequency and were, thus, impaired independent of the Fe or P supply. Thus, the nutritional signal may enter the root hair developmental pathway around the stage of root hair initiation and bulge formation. Finally, six mutants were screened that did not form root hairs under P deficiency but developed normal, when the plants were transferred to P-sufficient medium. One of these mutants, per2 (phosphate deficiency root hair defective2), was characterized phenotypically and genetically. In addition to the impaired root hair growth, the per2 mutant displayed a constitutively high lateral root number and accumulated an increased amount of anthocyanins under P starvation. Epistatic analysis revealed that per2 action is independent of early cell specification genes. The per2 mutation was mapped to a 87.6 kbp region on the upper arm of chromosome 3 containing 19 genes. The per2 phenotype has not been described before. Thus, PER2 is a potential new gene involved in root hair development under phosphate deficiency.

Soil acidity is a major factor limiting plant growth worldwide. Aluminum toxicity, which occurs only at low pH, has been extensively studied, whereas low pH stress has received much less attention. Studies on Al3+ and H+ toxicity make the underlying assumption that the effects of these stress factors are additive, and, therefore independent of each other. However, this is most likely not the case and low pH may be a factor which increases susceptibility to further injury by Al3+. There is evidence that low pH causes disruption in cell wall structure of growing cells, which might jeopardize cell wall functionality and integrity. It is likely that turgor pressure plays an important role in cell wall stress caused by low pH. The apoplastic metabolism of reactive oxygen species (ROS) can modulate cell wall extensibility by making or breaking bonds within and between cell wall polysaccharides. A major question is whether, similarly to yeast, plant cells have a cell wall integrity signaling and response system. Growing root hairs are sensitive to low pH and hypo-osmotic stress and are potentially good experimental systems for such investigations. The objectives of this study were: a) Optimize an experimental system to examine tomato (Solanum lycopersicum L. cv Micro-Tom) root hairs; b) Examine the response of root hairs to low pH and hypo-osmotic stress; c) Examine the role of oxidative modulation of the cell wall in these responses; and d) Evaluate the response of different hormonal mutants of Micro-Tom to these stress factors. Root hair elongation rates (µm.min-1) and the frequency of cell bursting were the major experimental parameters which were evaluated. Both low pH and, more markedly, hypo-osmotic stress caused significant reductions in elongation rates and the bursting of root hair tips. In a response curve to varying osmolarities of the external medium, root hair elongation rates increased with decreasing osmolarities until a threshold was reached and elongation rates decreased drastically and the bursting of root hairs began to be observed. Interactions between low pH and hypo-osmolarity were observed. The use of the inhibitor diphenylene iodonium (DPI) did not provide evidence for the involvement of plasma membrane NADPH in the response of root hairs to low pH and hypo-osmotic shock. However, a role for cell wall peroxidases was provided by use of the inhibitor salicylhydroxamic acid (SHAM). Root hairs of the hormonal mutants dgt (low sensitivity to auxin) and epi (ethylene super producer), but not not (deficient in abscisic acid), displayed a more effective response to hypo-osmotic shock than Micro-Tom, by decreasing elongation rates and cell bursting to a greater degree. This study provides strong evidence to suggest that root hairs have a cell wall integrity response system and that root hairs are potentially good cell model systems for such research
