Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses.

Project description:Global gene expression signatures was analysed through microarray expression profiling as a discovery platform to identify up and down regulated ESTs that represent genes involved in metabolic pathways in the leaf, fibrous root and storage root (tuber forming root) of sweetpotato (Ipomoea batatas) as affcted by high temperature stress (40oC) compared to ambient temperature (30oC). Also Global gene expression signatures was analysed by the same procedure to explore up and down regulated ESTs in tuberous root of sweet potato in comparison with fibrous root of Ipomoea cornea and identify unique ESTs that represent genes involved in tuber formation in sweet potato.

Project description:The exxpression profilling of chilling responsive and growth regulated microRNAs of maize hybrid ADA313 was conducted. Maize seedling were subjected to chilling temperature then meristem, elongation and mature growth zones were sampled. 321 known maize microRNA expression level were determined and compared between meristem, elongation and mature zones. Determining and validating of chilling responsive microRNAs associated with leaf growth of hybrid maize (Zea mays L.) ADA313

Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses. Wild type and AtCBF1OX transgenic potato plants were exposed to low temperature, high light, drought or kept under control conditions as described below in detail, and transcriptional changes induced by the different stresses were analyzed.

Project description:Five SAGE libraries were generated from A. thaliana leaf tissue collected at time points ranging from 30 minutes to one week of low temperature treatment (4°C). Over 240,000 high quality SAGE tags, corresponding to 16,629 annotated genes, provided a comprehensive survey of changes in the transcriptome in response to low temperature, from perception of the stress to acquisition of freezing tolerance.

Project description:Leaf rolling and discoloration are two chilling injury symptoms that are widely adopted as indicators for evaluation of cold tolerance at the seedling stage in rice, respectively. However, their relationship has not been well investigated, in particular the mechanism on how low temperature causes leaf rolling at a genome-wide level. In this study, a cold-tolerant japonica cultivar Lijiangxintuanheigu and a cold-sensitive indica cultivar Sanhuangzhan-2 were subjected to different low temperature treatments and physiological and genome-wide gene expression analysis were conducted. Our results showed that leaf rolling happened at temperatures lower than 11℃, but discoloration appeared at moderately low temperatures, such as 13℃. Chlorophyll contents of the two cultivars significantly decreased under 13℃, but didn’t change under 11℃. Contrastly, their relative water contents and the relative electrolyte leakages decreased significantly. Genome-wide gene expression profiling of LTH revealed that the calcium signaling related genes and the genes related to ABA degradation significantly changed under 11℃. Moreover, numerous genes in DREB, MYB, bZIP, NAC, Zin finger, bHLH, WRKY gene families were differently expressed. Furthermore, many aquaporin genes, the key genes in trehalose and starch synthesis were down-regulated under 11℃. These results suggest that the two chilling injury symptoms are controlled by different mechanisms. Cold-induced leaf rolling is associated with calcium and ABA signaling pathways, and subjected to regulation of multiple transcription regulators. The suppression of aquaporin genes and reduced accumulation of soluble sugars under cold stress result in reduction of water potential in cells and consequently, leaf rolling.
