Stimulation of cell elongation by tetraploidy in hypocotyls of dark-grown Arabidopsis seedlings

Project description:Transcriptional profiling of diploid and tetraploid Arabidopsis dark-grown hypocotyls. The aim of this study was to identify ploidy-related genes involved in the determination of cell size. This study showed that a group of genes involved in lipid transport/localization/binding were downregulated in a defined region of the tetraploid hypocotyl when compared to the diploid hypocotyl.

Identification of genes involved in secondary cell wall development in the hypocotyls of short day grown Arabidopsis

Project description:Arabidopsis, when grown under short day conditions (16 hours dark, 8 hours light, 22oC) develop extensive secondary thickened hypocotyls with both a vascular and cork cambium (Chaffey et al, 2002, Phys. Plant., 114:594-600). It has been found that once secondary xylem development is completed within the Arabidopsis hypocotyls, it closely resembles the structure of the wood of angiosperm trees (Chaffey et al, 2002, Phys. Plant., 114:594-600). We can utilise this model Arabidopsis tree to identify genes that are important for secondary cell wall formation in xylem cells and therefore important for wood development. Columbia plants were grown for 3 months under short day conditions and secondary thickened hypocotyls were snap-frozen in liquid nitrogen. RNA was isolated from these hypocotyls and submitted to NASC for probing against the ATH1-121501 full GeneChip. Keywords: growth_condition_design

Identification of glucose-TOR signaling early target genes in Arabidopsis seedling autotrophic transition stage

Project description:The goal of this experiment was to explore the molecular network of glucose-TOR signaling in Arabidopsis seedling autotrophic transition stage. We used the whole-genome microarrays to detail the global program of gene expression mediated by glucose and TOR. Arabidopsis WT and estradiol inducible RNAi-tor seedlings were germinated in low light condition for 3 days to deplete seed nutrient supply. Fifteen mM glucose was adding back to reactivate the quiescent seedlings and the samples were harvested for RNA isolation. Transcript profiles were analyzed and compared between with and without glucose treatment to identify early glucose-TOR target genes. Each experimental condition was repeated three times and total 12 samples were generated.

Differentially regulated genes in TOR knockdown Arabidopsis lines

Project description:Rapamycin-sensitive transgenic Arabidopsis lines (BP12) expressing yeast FK506 Binding Protein12 (FKBP12) were developed. Inhibition of TOR in BP12 plants by rapamycin resulted in slower overall root, leaf and shoot growth and development leading to poor nutrient uptake and light energy utilization. Genetic and physiological studies together with RNA-Seq and metabolite analysis of TOR-suppressed lines revealed that TOR regulates development and lifespan in Arabidopsis by restructuring cell growth, carbon and nitrogen metabolism, gene expression, ribosomal RNA and protein synthesis.

Light versus Dark gene expression in SAR11

Project description:We investigated the transcriptional response of cand. Pelagibacter ubique cultures to light and dark when grown under carbon replete and deplete conditions. Results: During exponential phase, few genes were differentially transcribed between light:dark growth conditions. In stationary phase, a high proportion (9.7%) of coding sequences were found differentially expressed between treatments; 4.7% being up-regulated in the light (n=64) and 4.9% being up-regulated in the dark (n=67). Several components of the oxidative phosphorylation pathway were up-regulated in the dark, supporting physiological data showing higher respiration rates in darkness than in the light under starvation conditions. We also observed up-regulation of a proton translocating pyrophosphate synthase (SAR11_1040), which may be an additional energy production mechanism utilized by SAR11 cells in the dark. Finally, we noted the up-regulation of pili formation genes in the array data, consistent with the observation of pili in dark grown cells via electron microscopy.
