Transcriptional feedback loops are a feature of circadian clocks in both animals and plants. We show that the plant circadian clock also incorporates the cytosolic signaling molecule cyclic adenosine diphosphate ribose (cADPR). cADPR modulates the circadian oscillator's transcriptional feedback loops and drives circadian oscillations of Ca2+ release. The effects of antagonists of cADPR signaling, manipulation of cADPR synthesis, and mathematical simulation of the interaction of cADPR with the ci ...[more]

rs11-07_opine2 - septante soil - Transcriptomic changes induced by opine production in Arabidopsis thaliana grown in natural soil

Project description:rs11-07_opine2 - septante soil - Transcriptomic changes induced by opine production in Arabidopsis thaliana grown in natural soil - Arabidopsis thalian Col- line was transformed in order to obtain transgenic lines that produce opine compound (octopine and mannopine). Transgenic lines producing respectively octopine and mannopine and the WT line were grown in greenhouse under long-day condition in pots containing half commercial compost and half soil of la Mérantaise and watered with water. Whole plant aged of one month were harvested and frozen in liquid nitrogen. The plants were ground with a mortar an pestls and RNA extraction was performed with the RNeasy extraction kit (QIAGEN) with cristal of PVP. The RNA concentration was measured on a NANODrop spectrophotometer.

cRNA hybridizations of 18 accessions of Arabidopsis thaliana under well-watered and mild soil drying

Project description:These data provide a basis for exploration of gene expression differences between physiologically diverse accessions of Arabidopsis thaliana. Recent studies have documented remarkable genetic variation among Arabidopsis thaliana accessions collected from diverse habitats and across its geographical range. Of particular interest are accessions with putatively locally adapted phenotypes – i.e., accessions with attributes that are likely adaptive under the climatic or habitat conditions of their sites of origin. These genotypes are especially valuable as they may provide insight into the genetic basis of adaptive evolution as well as allow the discovery of genes of ecological importance. Therefore we studied the physiology, genome content and gene expression of 18 physiologically diverse accessions. The gene expression studies were conducted under two levels of soil moisture and accompanied by physiological measurements to characterize early responses to soil moisture deficit.

Identification of circadian-regulated genes of Arabidopsis thaliana.

Project description:Most higher organisms, including plants and animals, have developed a time-keeping mechanism that allows them to anticipate daily fluctuations of environmental parameters such as light and temperature. This circadian clock efficiently coordinates plant growth and metabolism with respect to time-of-day by producing self-sustained rhythms of gene expression with an approximately 24-hour period. The importance of these rhythms has in fact been demonstrated in both phytoplankton and higher plants: organisms that have an internal clock period matched to the external environment possess a competitive advantage over those that do not. We used microarrays to identify circadian-regulated genes of Arabidopsis thaliana to elucidate how the clock provides an adaptive advantage by understanding how the clock regulates outputs and determining which pathways and processes may be under circadian control. Keywords: time course

Project description:These data provide a basis for exploration of gene expression differences between physiologically diverse accessions of Arabidopsis thaliana. Recent studies have documented remarkable genetic variation among Arabidopsis thaliana accessions collected from diverse habitats and across its geographical range. Of particular interest are accessions with putatively locally adapted phenotypes M-bM-^@M-^S i.e., accessions with attributes that are likely adaptive under the climatic or habitat conditions of their sites of origin. These genotypes are especially valuable as they may provide insight into the genetic basis of adaptive evolution as well as allow the discovery of genes of ecological importance. Therefore we studied the physiology, genome content and gene expression of 18 physiologically diverse accessions. The gene expression studies were conducted under two levels of soil moisture and accompanied by physiological measurements to characterize early responses to soil moisture deficit. The basic experimental design involves 18 accessions crossed with two environmental levels (well-watered soil and mild soil drying) and 3 biological replicates per accession/treatment combination.
