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:To screen genes related to the development of sweet potato tuberous roots, the high throughput sequencing of different stages of sweet potato tuberous roots was performed. The fibrous roots (FR; roots at 20 dap), developing tuberous roots (DR; roots at 60 dap) and mature tuberous roots (MR; roots at 120 dap) of Ipomoea batatas (L.) Taizhong 6 and MBP3 overexpressed lines were used for transcriptome analysis. Totally, we identified 5488 differentially expressed genes between different stage tuberous roots of Taizhong6 and 14312 differentially expressed genes between the tuberous roots of Taizhong6 and MBP3 overexpressed lines, by calculating the gene FPKM in each sample and conducting differential gene analysis. This study provides a foundation for the mechanism analysis of sweet potato tuberous root development.

Project description:The formation and development of storage roots is an intricate process regulated via a complex transcriptional regulatory network. To significantly advance our understanding of the molecular mechanisms governing storage root initiation and development in sweet potato, we performed a comprehensive analysis of transcriptome dynamics during root development.

Project description:A Microarray experiment was carried out in order to establish the genetic processes and control mechanism involved during storage root formation in Sweetpotato. A Sweetpotato cDNA chip was created from five varieties covering all the growth stages between them. mRNA from primordial root, fibrous root, pencil root and thick storage root was extracted from four varieties of Sweetpotato. The expression profiles were compared between the root growth stages. Keywords: Transcription profiling

The expression profiles were compared between the root growth stages. Keywords: Transcription profiling One condition experiment with time as a single parameter. Four different varieties of Sweetpotato (SPK004, Beauregard, Tanzania and Feng Shou Bai) with four growth stages (i.e. 3 weeks, 6 weeks, 10 weeks and 16 weeks) each were used for the comparison. Two pairs of biological replicates and one dye swap for each time point and variety were taken.

Project description:Mechanisms related to the development of cassava storage roots and starch accumulation remain largely unknown. To evaluate genome-wide expression patterns during cassava tuberization, a 60-mer oligonucleotide microarray representing 20,840 cassava genes was designed to identify differentially expressed transcripts in fibrous root, developing storage root and mature storage root. Using a random variance model and the traditional two-fold change method for statistical analysis, 912 and 3386 differentially expressed genes were identified related to the three different phases. Among 25 significant pathways identified, glycolysis/gluconeogenesis was the most important pathway signature due to its effects on other pathways. Rate-limiting enzymes were identified from each individual pathway, such as pectinesterase, enolase, L-lactate dehydrogenase and aldehyde dehydrogenase in glycolysis/gluconeogenesis, and ADP-glucose pyrophosphorylase, starch branching enzyme and glucan phosphorylase in sucrose and starch metabolism. This study revealed that dynamic changes in at least 16% of the transcriptome, including hundreds of transcription factors, oxidoreductases/transferases/hydrolases, hormone-related genes, and effectors of homeostasis, all of which highlight the complexity of this biological process. The reliability of differentially expressed genes in microarray analysis was further verified by quantitative real-time RT-PCR. The genome-wide transcription analysis facilitates our understanding of the formation of the storage root and deciphers key genes for further cassava improvement. Fibrous roots (FR), developing storage roots (DR) and mature storage roots (MR) were collected for RNA extractions from three independent healthy 4 month-old cassava (cultivar TMS60444) plants in the field .Two RNA samples extracted from stored storage root slices were used as technical repeats (TR) for quality control.
