Project description:Molecular cloning of Rf1 and Rf3 restorer genes in wheat
| PRJNA595448 | ENA
Project description:Plants of two non-restorer varieties of hexaploid winter wheat (Astoria, Grana) and two restorers ones (Patres and Primépi) were used to identify effective Rf (fertility restorer) genes by next generation sequencing on whole transcriptomes (RNA-seq).

Project description:Plants of two non-restorer varieties of hexaploid winter wheat (Astoria, Grana) and two restorers ones (Patres and Primépi) were used to Representational Difference Analysis (cDNA-RDA) to identify effective Rf (fertility restorer) genes. Anthers at the microspore stage were used as testers while anthers excised at the stage of pollen tetrads were selected as driver. The tester:driver ratio in three subsequent rounds of subtractive hybridization increased from 1:50, and 1:400 to 1:200000. Differential products obtained in the third subtraction of the size range from 200 to 800 bp were sequenced.

Project description:To better understand the regulatory mechanisms of water stress response in wheat, the transcript profiles in roots of two wheat genotypes, namely, drought tolerant 'Luohan No.2' (LH) and drought susceptible 'Chinese Spring' (CS) under water-stress were comparatively analyzed by using the Affymetrix wheat GeneChip®. A total of 3831 transcripts displayed 2-fold or more expression changes, 1593 transcripts were induced compared with 2238 transcripts were repressed, in LH under water-stress; Relatively fewer transcripts were drought responsive in CS, 1404 transcripts were induced and 1493 were repressed. Comparatively, 569 transcripts were commonly induced and 424 transcripts commonly repressed in LH and CS under water-stress. 689 transcripts (757 probe sets) identified from LH and 537 transcripts (575 probe sets) from CS were annotated and classified into 10 functional categories, and 74 transcripts derived from 80 probe sets displayed the change ratios no less than 16 in LH or CS. Several kinds of candidate genes were differentially expressed between the LH and CS, which could be responsible for the difference in drought tolerance of the two genotypes.

Project description:To improve the resources for map-based cloning and sequencing of the wheat genome, we established a physical map of the wheat chromosome 1BL with a high density of markers by hybridizing the newly developed INRA GDEC Triticum aestivum NimbleGen 12x17k ISBP microarray (A-MEXP-2312) with BAC pools from the 1BL physical map. Then, we managed to map 3912 ISBP on the wheat chromosome 1BL BACs. The values in the 'Factor Value[individual]' column represent the BAC pool that have been hybridized on the array. For example, the assay 1 correspond to the hybridization of a bulk of all DNA BAC of the plate 1 of the MTP (Minimum Tilling path) BAC library of the chromosome 1BL.

Project description:Wheat is the staple food of over 35% of the world’s population, accounts for 20% of all human calories, and its yield and quality improvement is a focus in the effort to meet new demands from population growth and changing diets. As the complexity of the wheat genome is unravelled, determining how it is used to build the protein machinery of wheat plants is a key next step in explaining detailed aspects of wheat growth and development. The specific functions of wheat organs during vegetative development and the role of metabolism, protein degradation and remobilisation in driving grain production are the foundations of crop performance and have recently become accessible through studies of the wheat proteome. With the aim of creating a resource complementary to current genome sequencing and assembly projects and to aid researchers in the specific analysis and measurement of wheat proteins of interest, we present a large scale, publicly accessible database of identified peptides and proteins derived from the proteome mapping of Triticum aestivum. This current dataset consists of twenty four organ and developmental samples in an online interactive resource allowing the selection, comparison and retrieval of proteomic data with rich biochemical annotation derived from multiple sources. Tissue specific sub-proteomes and ubiquitously expressed markers of the wheat proteome are identified alongside hierarchical assessment of protein functional classes and their presence in different tissues. The impact of wheat’s polyploid genome on proteome analysis and the effect on defining gene specific and protein family relationships is accounted for in the organisation of the data. The dataset will serve as a vehicle to build, refine and deposit confirmed targeted proteomic assays for wheat proteins and protein families to assess function.

Project description:This study evaluated the level of genetic variation among 543 wheat associations differing in K-deficiency tolerance at seedling and adult plant stages. Two of the 543 wheat associations, i.e. KN9204 and BN207, were identified as extreme K-deficiency tolerant and sensitive cultivars, respectively. We further conducted transcriptomic and metabolomics analyses using the roots of KN9204 and BN207 under normal or K-deficient conditions.Integrated analysis of gene expression and metabolite profiles revealed that dramatically more genes including those involved in ion homeostasis, cellular reactive oxygen species (ROS) homeostasis and glutamine synthetase pathways were induced in KN9204 as compared with BN207 under K-deficient conditions, which might indicate their unique roles in regulating plant K-starvation tolerance. These findings provided a better understanding of molecular responses of root adaptive strategies to K deprivation in wheat.

Project description:Agrobacterium-mediated plant transformation is an extremely complex and evolved process involving genetic determinants of both the bacteria and the host plant cells. However, the mechanism of the determinants remains obscure, especially in some cereal crops such as wheat, which is recalcitrant for Agrobacterium-mediated transformation. In this study, differentially expressed genes (DEGs) were analyzed in wheat callus cells co-cultured with Agrobacterium by using RNA sequencing (RNA-seq). Note: All samples in SRA were assigned the same sample accession (SRS417803). This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
