Project description:To analyze the gene regulatory network controlled by SP6A under warm temperatures, we hybridized an Agilent 60-mer microarray with probes corresponding to the RNA extracted out of leaves from WT and StSP6Aox potato plants grown at 22ºC and 28ºC.

Project description:A IR64 variety of rice was grown in a field plot at the International Rice Research Institute (IRRI) in the Philippines. The data gained from the experiment provides information of the daily transcriptional changes occur in panicle tissue during an important developmental period under control and warm night temperatures.

Project description:In this study we were interested in identifying the gene networks that are responsive to chronic heat treatment in a switchgrass cultivar that is widely grown in the south-western USA and where 38C day temperatures have been reported for more than 100 days in the recent years. Switchgrass Alamo plants were subjected to chronic heat stress for 50 days (38 C/30C; day/night) or maintained under optimal conditions (28C/20C). Leaves were collected at the end of the heat regime for transcriptome analysis.

Project description:Elevated growth temperatures are negatively affecting crop productivity and increasing yield losses. Root traits associated with improved adaptation to rising temperatures are a promising approach to generate new varieties better suited to face the environmental constrains caused by climate change. In this study, we identified various Brassica napus roots traits altered in response to warm temperature. Thus, different combination of changes in specific root traits results in an extended and deeper root system. This overall root growth expansion facilitates root adaptation by maximizing root-soil surface interaction and increasing its ability to explore extended soil areas. We associated these traits to coordinated cellular events, including changes in cell division and elongation rates, that drive the increase in root growth triggered by warm temperature. Comparative genome wide transcriptomic analysis revealed the main genetic determinants of these RSA changes and uncovered the necessity of a tight regulation of the heat shock stress response to adjust root growth to warm temperature. Our work provides a phenotypic, cellular and genetic framework of root response to warming temperatures that will help to harness root adaptation mechanisms for crop yield improvement under the future climatic scenario.

Project description:St (common potato) is a freezing sensitive species unable to cold acclimate. The close wild relative Sc is freezing tolerant and able to cold acclimate. Here we compare the cold transcriptome of these two species with different levels of freezing tolerance. We also identify the putative CBF regulons by comparing the transcriptomes of wild type plants with that of 35S::AtCBF3 transgenic lines in both species. Plants were grown in 16:8 photoperiod. Eight hours after dawn, plants were either transfered to cold or kept in the warn. Wild type S. tuberosum and S. commersonii were grown at 2oC for 2h, 24h and 7 days. Wild type plants grown under warm temperatures for 2h was used as control for 2h cold samples; wild type warm grown plants for 24h were used as controls for 24h and 7 days cold samples. Under warm conditions, S. commersonii 35S::AtCBF3 lines were compared to S. commersonii wild type plants (same thing was done for S. tuberosum).

Project description:Chytridiomycosis is an emerging infectious disease of amphibians caused by the chytrid Batrachochytrium dendrobatidis (Bd). The disease has been associated with global amphibian declines and is driving the species in the wild to extinction. Using DNA microarray technology we have analysed transcriptional changes in Xenopus tropicalis during the course (7 and 42 days) of infection by Bd under warm (26oC) and cold (18oC) temperatures.

Project description:Temperature is a prominent environmental stimulus that influences life span. Previous studies indicate that in Caenorhabditis elegans, thermosensory perception in the AFD neuron maintains life span at warm temperatures. How thermosensation is translated into neuronal signals that shape aging remains elusive. We found that the Caenorhabditis elegans CREB crh-1, as well as several key genes in AFD thermosensory transduction, were specifically required for normal life span at warm temperatures. crh-1 acted in the AFD to increase transcription of the CRE-containing neuropeptide gene flp-6 in a temperature-dependent manner. Both crh-1 and flp-6 were necessary and sufficient for longevity at warm temperatures, and their effects depended on the AIY interneuron. Moreover, flp-6 signaling downregulated ins-7/insulin and several insulin pathway genes, whose activity compromised life span. We postulate that temperature experience is integrated in the thermosensory neurons to generate CREB-dependent neuropeptide signals that antagonize insulin signaling and promote temperature-specific longevity.

Project description:Background: Understanding the genetic elements that contribute to key aspects of coffee biology will impact future agronomical improvements for this economically important tree. The past years, EST collections were generated in Coffee, opening the possibility to create new tools for functional genomics. Results: The project PUCE CAFE, set up by the scientific consortium NESTLE/IRD/CIRAD has developed of long oligonucleotide coffee array using public coffee EST sequences mainly obtained from different stages during fruit development and leaves in Coffea canephora (Robusta). We have performed a validation experiment in order to check the array usability and the reproducibility of hybridizations. Conclusion: We have generated the first 15K Coffee array during this three years project PUCE CAFE, granted by The French National Research Agency (ANR, Programme Génoplante) . This new tool was dedicated to large scale transcriptomic analysis during grain development of Coffea canephora grown in different countries . Furthermore, other analysis have been also initiated by the different partners like analysis of polyploidy or drought resistance. In any case, at the end of the project, the generated arrays will be available to the international scientific community. three biological replicates were made for each tissue analyzed (i.e. leaves, flowers and mature beans). The following comparisons were made: Bean-Flower, Leaf-Flower and Leaf-Bean. In all, we performed microarray analyses on 18 slides [3 (replicates) x 2 (dyes) x 3 (organs)]
