Project description:Wheat seed germination and seminal root growth can be inhibited by treatment with exogenous ABA We used Affymetrix GeneChip Wheat Genome Array to detail transcriptional programs affected by ABA during imbibition After-ripened seeds imbibed in ABA for 24 h were used for RNA extraction and hybridization on Affymetrix GeneChip. After-ripened seeds were generated by storing dormant seeds at room temperature for 10 months.

Project description:Wheat seed dormancy is released by after-ripening, and germination and seminal root growth of after-ripened/non-dormant seeds can be inhibited by treatment with exogenous ABA. We used Affymetrix GeneChip Wheat Genome Array to detail transcriptional programs affected by after-ripening of dormant seeds and imbibition of after-ripened seeds in ABA.

Project description:We identified a regulator of Arabidopsis thaliana seed germination: FLOE1 (AT4G28300). We used RNA-seq to uncover genes that are differentially regulated in dry seeds, imbibed seeds and seeds imbibed in 220mM NaCl in mutant lines complemented with a ΔDS deletion version of FLOE1 (ΔDS) compared to mutants complemented with a WT version of FLOE1 (+WT).

Project description:After-ripening induced seed dormancy release in wheat is associated with mRNA oxidation. We used Affymetrix GeneChip Wheat Genome Array to identify mRNAs differentially oxidized by after-ripening Dormant and after-ripened seeds in dry state were used for isolating oxidized mRNAs and hybridization on Affymetrix GeneChip. After-ripened seeds were generated by storing dormant seeds at room temperature for 10 months.

Project description:Objective: Germination of wheat maximizes phytochemical content and antioxidant activity while altering chemical composition, gluten content, and pasting properties. We previously reported marked changes in gene expression in soybean prior to germination before the radicle had grown from a seed. The present study investigated whether imibibition induces similar changes in wheat. Methods: Changes in gene expression profiles of wheat during short-term imbibition (0, 16, and 24 h) were evaluated by DNA microarray analysis. Gene Ontology (GO) analysis was carried out to categorize the function of genes with altered expression. The expression of genes encoding enzymes associated with starch breakdown was evaluated by quantitative real-time PCR, and changes in enzymatic activity were assessed with functional assays. Pasting properties of flour made from wheat seeds imbibed for different times were examined with a Rapid Visco Analyzer. The protein profile was determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis, and gluten content was quantified. Results: The GO analysis revealed that genes related to cellulose and cell wall synthesis were upregulated by imbibition for 16 h whereas those associated with polysaccharide catabolism and nucleosome assembly were upregulated in the subsequent 8 h. α-Amylase expression was highest after 24-h imbibition, with a corresponding increase in enzymatic activity. The pasting properties of wheat flour decreased when seeds were imbibed for over 16 h. Gluten was not degraded until 48 h imbibition. Conclusion: Short-term imbibition of wheat can produce a new type of starch with improved physical and functional properties that may be more appealing to consumers.
