Transgenic lines of the potato cultivar White Lady expressing the trehalose-6-phosphate synthase (TPS1) gene of yeast exhibit improved drought tolerance, but grow slower and have a lower carbon fixation rate and stomatal density than the wild-type. To understand the molecular basis of this phenomenon, we have compared the transcriptomes of wild-type and TPS1-transgenic plants using the POCI microarray containing 42,034 potato unigene probes. We show that 74 and 25 genes were up-, and down-regula ...[more]

Transcript profiling of the wild type Arabidopsis grown under different photoperiods

Project description:Arabidopsis rosette leaves were harvested from plants grown under different photoperiods under 100 M-5mol photons m-2 s-1 at 20 M-0C. In the first experiment plants grown under short day conditions 8L/16D (8 h light / 16 h dark) for 4 weeks were compared with plants grown under long day (16L/8D) for 3 weeks. In the second experiment plants grown under 12L/12D for 2 weeks were compared with plants grown first 2 weeks under 12L/12D and then two days under short day (8L/16D) conditions.

Transcriptome alterations associated with TMV-resistance in transgenic tobacco plants expressing the genomic RNA of the virus

Project description:Agilent 4x44k tobacco micro array of wild type tobacco (WT) and whole tobacco mosaic virus (TMV) containing transgenic tobacco plants. The transgenic plants before resistance break (BRB-6 weeks), after resistance break (ARB-8 weeks) and wild type tobacco plants infected with TMV (TMVi-9weeks) leaves were analyzed. Three biological replicates were performed for each sample.

Transcription profiling of Medicago truncatula responses to Colletotrichum species

Project description:We have previously showed a strong genetic determinant governing resistance of the M. truncatula A17 line to C. trifolii is located in a chromosomal region at the top of chromosome 4 (Ameline-torregrosa et al., 2008). This region also contains the RCT1 gene which has been shown to confer resistance to C. trifolii when transferred to a susceptible alfalfa plants (Zhu et al.), In order to evaluate the role of this region in the response to non-adapted Colletorichum species and to compare this response to those induce by C. trifolii, two M. truncatula near-isogenic lines differing only in this chromosomal region were used for transcript profiling experiments. These two lines were issued from a recombinant-inbred collection obtained from a A17-F83005.5 cross (Cazaux et al., in preparation). Plant inoculations were done on two-week-old entire plants by spraying a conidial suspension of C. trifolii or C. lindemuthianum to avoid possible artifacts which can be observed on detached leaves (Liu et al., 2007). RNA was extracted from leaves collected at 1dpi and 3dpi and transcript profiling was performed using Mt16kOLI1Plus chips (Thompson et al., 2005).

Transcription profiling of Arabidopsis dehydration on soil

Project description:Arabidopsis plants were grown in plastic pots filled with peat moss for 3 weeks (principal growth stage 1.07-1.08) under a 16 h light/8 h dark regimen (40 ± 10 ?mol photons/m2/s) at 22 C.Dehydration treatment: The 3-week-old plants were grown for 2 or 3 days without watering. To obtain accurate results, we carefully raised single plants in Petri dishes, each containing an equal amount of soil. Soil moisture contents were calculated from soil dry weight. Untreated; the soil moisture content was 84.3%. Under dehydration, on the second day, the soil moisture content was 51.1%. Under dehydration, on the third day, the moisture content was 11.6%.
