Project description:Experiments were achieved on Arabidopsis thaliana. Transcriptional profiling of roots and shoots from plants treated with lead were compared to plants treated in similar conditions without lead. Four weeks old A. thaliana seedlings were treated in hydroponic cultures with Pb during 3 days, by adding or not 40 µM Pb(NO3)2.

Project description:Roots are very important at different stages of plant growth, and the formation of lateral roots is essential for strengthening the roots and absorbing nutrients from the soil. Therefore, it is of great significance to uncover the molecular mechanism of lateral root development in plants for understanding plant life process and improving plant adaptation to environment. As an important post-translational modification of small protein types, small ubiquitin-like modifier is involved in many biological processes such as transcriptional regulation, cell cycle regulation, and immune response. SUMO E3 ligase plays a key role in the SUMO process and plays an important role in plant growth and development. In Arabidopsis thaliana, SIZ1 encodes a SUMO E3 ligase, which plays an important role in plant life, especially in stress response. We analyzed the expression sites of SIZ1 and found that it was obviously expressed in lateral roots, especially in the nucleus of lateral roots. Previous studies on SIZ1 mainly focused on biological stress and abiotic stress, but the molecular mechanism of SIZ1 regulating lateral roots has not been studied. We propose a mechanism by which hemicylation of LBD29 mediated by SIZ1 regulates the occurrence of lateral roots in Arabidopsis Thaliana, which provides a new idea and direction for subsequent research on lateral root development.

Project description:Oomycetes from the genus Phytophthora are fungus-like plant pathogens that are devastating for agriculture and natural ecosystems. Due to particular physiological characteristics, no treatments against diseases caused by oomycetes are presently available. To develop such treatments, it appears essential to dissect the molecular mechanisms that determine the interaction between Phytophthora species and host plants. The present project is focused on the molecular mechanisms that underlie the compatible plant-oomycete interaction and plant disease. The laboratory developed a novel interaction system involving the model plant, Arabidopsis thaliana, and Phytophthora parasitica, a soil-borne pathogen infecting a wide host range, thus representing the majority of Phytophthora species. A characteristic feature of the compatible Arabidopsis/P. parasitica interaction is an extended biotrophic phase, before infection becomes necrotrophic. Because the initial biotrophic phase is extremely short on natural (e.g. solanaceous) hosts, the Arabidopsis system provides the opportunity to analyze, for both interaction partners, the molecular events that determine the initiation of infection and the switch to necrotrophy. The present project aims at analyzing the compatible interaction between A. thaliana roots and P. parasitica. The Affymetrix A. thaliana full genome chip will be used to characterize modulations of the transcriptome occurring over a period of 24h from the onset of plant root infection to the beginning of necrotrophy. Parallel to this study, a custom-designed P. parasitica biochip will enable analyzing of P. parasitica gene expression during the same stages.

Project description:Background: Polycyclic aromatic hydrocarbons (PAHs) are toxic, widely-distributed, environmentally persistent, and carcinogenic byproducts of carbon-based fuel combustion. Previously, plant studies have shown that PAHs induce oxidative stress, reduce growth, and cause leaf deformation as well as tissue necrosis. To understand the transcriptional changes that occur during these processes, we performed microarray experiments on Arabidopsis thaliana L. under phenanthrene treatment, and compared the results to published Arabidopsis microarray data representing a variety of stress and hormone treatments. In addition, to probe hormonal aspects of PAH stress, we assayed transgenic ethylene-inducible reporter plants as well as ethylene pathway mutants under phenanthrene treatment. Results: Microarray results revealed numerous perturbations in signaling and metabolic pathways that regulate reactive oxygen species (ROS) and responses related to pathogen defense. A number of glutathione S-transferases that may tag xenobiotics for transport to the vacuole were upregulated. Comparative microarray analyses indicated that the phenanthrene response was closely related to other ROS conditions, including pathogen defense conditions. The ethylene-inducible transgenic reporters were activated by phenanthrene. Mutant experiments showed that PAH inhibits growth through an ethylene-independent pathway, as PAH-treated ethylene-insensitive etr1-4 mutants exhibited a greater growth reduction than WT. Further, phenanthrene-treated, constitutive ethylene signaling mutants had longer roots than the untreated control plants, indicating that the PAH inhibits parts of the ethylene signaling pathway. Conclusions: This study identified major physiological systems that participate in the PAH-induced stress response in Arabidopsis. At the transcriptional level, the results identify specific gene targets that will be valuable in finding lead compounds and engineering increased tolerance. Collectively, the results open a number of new avenues for researching and improving plant resilience and PAH phytoremediation.
