Project description:The pistillody mutant wheat (Triticum aestivum L.) plant HTS-1 exhibits homeotic transformation of stamens into pistils or pistil-like structures. Unlike common wheat varieties, HTS-1 produces three to six pistils per floret, potentially increasing the yield. Thus, HTS-1 is highly valuable in the study of floral development in wheat. In this study, we conducted RNA sequencing of the transcriptomes of the pistillody stamen (PS) and the pistil (P) from HTS-1 plants, and the stamen (S) from the non-pistillody control variety Chinese Spring TP to gain insights into pistil and stamen development in wheat.

Project description:The analysis of gene expression during wheat development: Gene expression measurements were carried out on a developmental tissue series for wild-type wheat (cv. Chinese Spring) using the Affymetrix Wheat GeneChip. Thirteen tissues at defined developmental stages were chosen to match the barley (cv. Morex) tissue series of Druka et al. 2006 that used the Affymetrix Barley1 GeneChip. Three replicates of: root tissue at two different developmental stages, leaf, crown, caryopsis, anther, pistil, inflorescence, bracts, mesocotyl, endosperm, embryo and coleoptiles were hybridised. Comparisons between this wheat data and the barley dataset were performed and are available at http://contigcomp.acpfg.com.au [PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Tim Sutton. The equivalent experiment is TA3 at PLEXdb.]

Project description:Integration of multi-omics data can provide information on biomolecules from different layers to illustrate the complex biology systematically. Here, we built the first global quantitative atlas containing transcriptomes, proteomes, phospho-proteomes and acetyl-proteomes of 20 tissues in common wheat. We identified 132,570 transcripts, 32,256 proteins, 69,364 phosphorylation sites, and 34,974 acetylation sites across wheat development stages. Our data demonstrated that homoeolog expression bias exists divergence at different omics layers. Regulatory networks dissected critical proteins or genes controlling important biology processes. Four wheat trait-gene families refer to timely flowering, disease resistance, starch biosynthesis-related genes, and seed storage proteins were used as examples to verify our data and shed novel inlight on the importance of post-translational modifications in wheat previously unknown. Importantly, a novel Fusarium crown rot (FCR) resistant gene delta-1-pyrroline-5-carboxylate synthase (TaP5CS1) was identified by FCR-responsive multi-omics techniques. We found that TaP5CS1 confers FCR tolerance via increased proline content and is regulated by histone deacetylase 9 (TaHDA9). Our multi-omics atlas data will accelerate function and mechanism studies of important traits in wheat.

Project description:Pistil development is an important developmental process that directly affects the yield of Prunus sibirica. Through transcriptome sequencing analysis of clones with abortive pistil (No. 595) and normal pistil (No. 28) of Prunus sibirica, a total of 1950 significantly differentially expressed genes were obtained, among which 1000 genes were up-regulated and 950 genes were down-regulated. The results provide a theoretical basis for further investigation of the formation mechanism of pistil abortion.

Project description:Pollen tubes extend through pistil tissues and are guided to ovules where they release sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic medium, their trajectory is random and their growth rates are slower compared to growth in pistil tissues. Furthermore, interaction with the pistil renders pollen tubes competent to respond to guidance cues secreted by specialized cells within the ovule. The molecular basis for this potentiation of the pollen tube by the pistil remains uncharacterized. We used a surgical procedure to obtain large quantities of uncontaminated pollen tubes that grew through the pistil and defined their transcriptome by microarray analysis. We also characterized the transcriptome of in vitro-grown pollen tubes (for 0.5hours or 4hours) and dessicated mature pollen in Arabidopsis.

Project description:Introduction: Pre-harvest Sprouting (PHS) seriously affects wheat quality and yield. However, to date there have been limited reports. It is of great urgency to breed resistance varieties via quantitative trait nucleotides (QTNs) or genes for PHS resistance in white-grained wheat. Methods: 629 Chinese wheat varieties, including 373 local wheat varieties from 70 years ago and 256 improved wheat varieties were phenotyped for spike sprouting (SS) in two environments and genotyped by wheat 660K microarray. These phenotypes were used to associate with 314,548 SNP markers for identifying QTNs for PHS resistance using several multi-locus genome-wide association study (GWAS) methods. Their candidate genes were verified by RNA-seq, and the validated candidate genes were further exploited in wheat breeding. Results: As a result, variation coefficients of 50% and 47% for PHS in 629 wheat varieties, respectively, in 2020-2021 and 2021-2022 indicated large phenotypic variation, in particular, 38 white grain varieties appeared at least medium resistance, such as Baipimai, Fengchan 3, and Jimai 20. In GWAS, 22 significant QTNs, with the sizes of 0.06% ~ 38.11%, for PHS resistance were stably identified by multiple multi-locus methods in two environments, e.g., AX-95124645 (chr3D:571.35Mb), with the sizes of 36.390% and 45.850% in 2020-2021 and 2021-2022, respectively, was detected by several multi-locus methods in two environments. As compared with previous studies, the AX-95124645 was used to develop Kompetitive Allele-Specific PCR marker QSS.TAF9-3D (chr3D:569.17Mb~573.55Mb) for the first time, especially, it is available in white-grain wheat varieties. Around this locus, nine genes were significantly differentially expressed, and two of them (TraesCS3D01G466100 and TraesCS3D01G468500) were found by GO annotation to be related to PHS resistance and determined as candidate genes. Discussion: The QTN and two new candidate genes related to PHS resistance were identified in this study. The QTN can be used to effectively identify the PHS resistance materials, especially, all the white-grained varieties with QSS.TAF9-3D-TT haplotype are resistant to spike sprouting. Thus, this study provides candidate genes, materials, and methodological basis for breeding wheat PHS resistance in the future.
