Project description:au13-03_cuc2 - identification of target genes regulated by cuc2 in a.thaliana shoot apical meristem. - Identification of genes specifically targeted by the CUC2 transcription factor that defines the margins of the floral meristem of Arabidopsis thaliana. - identify genes specifically targeted by CUP-SHAPED COTYLEDON 2 (CUC2), a transcription factor required for embryonic shoot meristem formation and specification of the organ boundary in A.thaliana
Project description:This study was aimed to determine roles of individual myosins in organelle trafficking in plant cell. Expression of Myosin XI-K was suppressed in transgenic A.thaliana by using RNAi approach. To ensure that the RNAi-induced gene silencing was specific and did not affect expression of other myosins, a microarray analysis was performed. Keywords: RNAi-mediated posttranscriptional gene silencing, Myosin expression levels
Project description:rs10-05_tcv - gene profiling of turnip crinkle virus (tcv) sirna - 1. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA in A.thaliana? 2. There are also differentially regulated during an evolution and a fitness process? - This is a plant evolution project on TCV in which, the biological questions are: 1. What are the genes (including miRNA precursors) that are differentially regulated in Col0 and dcl234 mutant in wt conditions? 2. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA in Col0 and dcl234 mutant? 3. There are also differentially regulated between the plant generations 1 (G1) and 11 (G11)? 4. What are the genes (including miRNA precursors) that are differentially regulated in a set of viral siRNA after fitness experiment? 24 dye-swap - gene knock out,treated vs untreated comparison
Project description:Chlorophyll plays critical roles in photosynthetic light harvesting, energy transduction and plant development. In this study, a novel wucai (Brassica campestris L.) germplasm with green outer leaves and yellow inner leaves at the adult stage (W7-2) was used to examine chlorophyll metabolism response to cold acclimation. A green leaf wucai genotype without leaf color changes named W7-1 was selected as the control to evaluate the chlorophyll metabolism changes of W7-2. Compared to W7-1, the contents of chlorophyll a (Chl a) and chlorophyll b (Chl b) in W7-2 were significantly reduced at five developmental stages (13, 21, 29, 37 and 45 days after planting (DAP). An iTRAQ-based quantitative proteomic analysis was carried out at 21 and 29 DAP according to the leaf color changes in both of genotypes. A total of 1409 proteins were identified, of which 218 showed differential accumulations between W7-2 and W7-1 during the two developmental stages.
Project description:pc_arcole - arcole / pgpr - What are the genes implicated in the efficiency of nitrogenous nutrition when A.thaliana is inoculated with a PGPR (Plant Growth Promoting Rhizobacteria)? - A.thaliana seeds germinated and grew during ten days until they were transfered in 6 different media: 0,5 mM nitrate with PGPR (Plant Growth Promoting Rhizobacteria), 0,5mM nitrate without PGPR, 2mM nitrate with PGPR, 2mM nitrate without PGPR, 20 mM nitrate with PGPR, 20 mM nitrate without PGPR. Young plantlets grew 7 days in these new mediums. Shoots are collected in eppendorf. 6 dye-swap - dose response,organ comparison,treated vs untreated comparison
Project description:A gradual decline in renal function occurs even in healthy aging individuals. In addition to aging per se, concurrent metabolic syndrome and hypertension, which are common in the aging population, can induce mitochondrial dysfunction, and inflammation, which collectively contribute to age-related kidney disease. Here we studied the role of the nuclear hormone receptors, the estrogen related receptors (ERRs) in regulation of age-related mitochondrial dysfunction and inflammation. ERRs are decreased in aging human and mouse kidneys and preserved in aging mice with lifelong caloric restriction (CR). Our studies identified ERRs as important modulators of age-related mitochondrial dysfunction and inflammation. ERRα, ERRβ, and ERRγ levels are decreased in the aging kidney. Remarkably, only a 4-week treatment of 21-month-old mice with the pan ERR agonist reversed the age-related increases in albuminuria and podocyte loss, mitochondrial dysfunction and inflammatory cytokines, including the cGAS-STING and STAT3 signaling pathways. A 3-week treatment of 21-month-old mice with a STING inhibitor reversed the increases in inflammatory cytokines and the senescence marker p21 but also unexpectedly reversed the age-related decreases in PGC-1α, ERRα, mitochondrial complexes and Mcad expression.
