Project description:Allohexaploid bread wheat (Triticum aestivum, L.) provides ~ 20% of calories consumed by humans. Hitherto lack of genome sequence for the three homoelogous and highly similar bread wheat genomes (A, B and, D) impeded expression analysis of the grain transcriptome. We used novel genome information to analyze the cell type specific expression of homeologous genes in the developing wheat grain.

Project description:Bread wheat (Triticum aestivum) has a large, complex and hexaploid genome consisting of A, B and D homoeologous chromosome sets. Therefore each wheat gene potentially exists as a trio of A, B and D homoeoalleles, each of which may contribute differentially to wheat phenotypes. We describe a novel approach combining wheat cytogenetic resources (chromosome substitution ânullisomic-tetrasomicâ lines) with next generation deep sequencing of gene transcripts (RNA-seq), to directly and accurately identify homoeologue-specific single nucleotide variants and quantify the relative homoeoallelic contribution to gene expression. We obtained mRNA-Seq datasets from non-normalized cDNA libraries created from shoot and root tissues of the euploid bread wheat cultivar Chinese Spring, from which the nullitetra lines are derived, from complete sets of chromosome 1 and 5 nullitetras, and from extant relatives of the diploid A (Triticum urartu) and D (Aegilops tauschii) genome donors, herein referred to as A and D genome diploids

Project description:The high molecular weight (HMW) subunits of wheat glutenin are synthesised only in the starchy endosperm tissue of the developing wheat grain. We compared the expressed genomes of the transgenic wheat line B102,1-1 (Rooke et al. Transgene inheritance, segregation and expression in bread wheat. Euphytica 129, 301-309 (2003)). Both lines were shown to express the HMW-GS Ax1 gene (Halford, N.G. et al. Analysis of HMW glutenin subunits encoded bychromosome 1A of bread wheat (Triticum aestivum L.) indicates quantitative effects on grain quality. Theor Appl Genet 83, 373-378 (1992).) to the expressed genome of conventionally bred wheat line L88-18 (Lawrence et al. Dough and baking quality of wheat lines in glutenin subunits controlled by Glu-A1, Glu-B1 and Glu-D1 loci. J. Cereal. Sci. 7,109-112 (1988)) which results in the same effects on traits. Transcriptomes comparison analysis was performed in endosperm tissue (14 and 28 days post anthesis-dpa) and in leaf tissue (8 days post germination dpg), respectively. Each of the transcriptome comparisons was performed using three biological replicates (i.e. per line/tissue /developmental stage selected). Hybridisations were performed in reverse dye labelling.Exceptionally, biological replica 2 was only performed for B102,1-1 (green)/L88-18 (red) labelling and not swap
