Project description:Purpose: The goal of this experiment was to use RNA-seq to compare the two commercial cotton species Gossypium hirsutum and Gossypium barbadense and determine what transcripts may account for the better fiber quality in the latter. Methods: RNA was extracted from Gossypium barbadense or Gossypium hirsutum fibers at 10, 15, 18, 21, and 28 days post anthesis. Paired-end, 100-bp RNA-seq was performed on an Illumina HiSeq2000 and the reads were mapped to the Gossypium raimondii genome at www.phytozome.net and non-homologous contig assemblies from Gossypium arboreum. Results from RNA-seq were combined with non-targeted metabolomics. Results: Approximately 38,000 transcripts were expressed (RPKM>2) in each fiber type and approximately 2,000 of these transcripts were differentially expressed in a cross-species comparison at each timepoint. Enriched Gene Ontology biological processes in differentially expressed transcripts suggested that Gh fibers were more stressed. Conclusions: Both metabolomic and transcriptomic data suggest that better mechanisms for managing reactive oxygen species contribute to the increased fiber length in Gossypium barbadense. This appears to result from enhanced ascorbate biosynthesis via gulono-1,4-lactone oxidase and ascorbate recycling via dehydroascorbate reductase. See Bioproject PRJNA263926 and SRA accession SRP049330 for study design and raw sequencing data and Bioproject PRJNA269608 and TSA accession GBYK00000000 for Gossypium arboreum assembled contig sequences used for transcriptome mapping - Cotton fiber mRNA from 10,15,18,21 and 28 day post anthesis fiber from either Gossypium hirusutm or Gossypium barbadense was sequenced and differential gene expression analysis was conducted between species for each timepoint and between adjacent timepoints. Each timepoint was representative of fiber from 9 individual plants processed as 3 biological replicate pools (material from 3 individual plants per pool).

Project description:We compared different days post-anthesis (5DPA, 10DPA, 15DPA and 25DPA) differentially expressed genes (DEGs) in fiber development between G. hirsutum and G. barbadense. In addition, we analysis the differentially expressed genes (DEGs) function using the database for annotation, visualization and integrated discovery (DAVID). Overall, gene expression pattern have significantly difference between G. hirsutum and G. barbadense. In this study, G. barbadense DEGS in different two DPA are significantly more than G. hirsutum. In addation, there are 18937 DEGs were identified in fruit development and postembryonic development pathways and only upregulated in G. barbadense only. Taken together, these findings suggest that there are considerable differences of gene expression between G. hirsutum and G. barbadense in cotton fiber development different stages.

Project description:Seed germination, a key initial event in the plant life cycle, directly affects the yield and quality of cotton. Gossypium barbadense and Gossypium hirsutum are gradually evolved through polyploidization resulting in different characteristics, and the existence of this interspecific variation lacks genetic and molecular explanation. In this study, we compared the proteomes between G. barbadense and G. hirsutum during seed germination. In all we identified 2741 proteins for G. barbadense and 3759 proteins for G. hirsutum. Through functional enrichment, we found that seeds germinate by first repairing damaged DNA and proteins, as well as mobilizing stored substances such as carbohydrates, proteins and lipids for energy production to initiate life activities, followed by progressive development through cell division and other processes. We also performed homology analysis and found 21711 orthogroups including 2761 species-specific orthogroups for G. hirsutum and 527 ones for G. barbadense. Further differential analysis in 915 single-copy orthogroups between the two cottons was conducted, indicating that most of the differentially expressed proteins in G. barbadense were related to carbon metabolism, while most of the differentially expressed proteins in G. hirsutum were associated with stress response.

Project description:affy_cotton_2011_12 - affy_cotton_2011_12 - In this study we characterized the fiber transcriptomes of the two species, Gossypium hirsutum and Gossypium barbadense that were parental genotypes of a RIL mapping population used previously for phenotypic QTL and expression QTL mapping., We used 454 deep pyrosequencing to characterize cDNAs from developing fibers at two key developmental time-points; 10 and 22 days post anthesis. A unigene set was assembled and annotated, and differential digital gene expression was assessed from the different time-point and genotype representations of the reads within assembled contigs. As a complementary approach, we conducted microarray-based hybridization profiling using the cotton Affymetrix gene chip and labeled cDNAs from fibers at 11 dpa and for the same two genotypes and compared differentially expressed genes identified by the two platforms. The 454 unigenes were also mined for the presence of microsatellite repeats and SNPs that will be useful markers for mapping and marker-assisted selection in cotton improvement.-Total RNA was extracted from 11 dpa-old fibers from the two genotypes, Guazuncho 2 (Gossypium hirsutum) and VH8-4602 (G. barbadense), and included two replicates of each. RNA was checked for quality and quantity using an Agilent Bioanalyser 2100 (Agilent Technologies, Santa Clara, CA, USA, http://www.home.agilent.com) following the manufacturer’s recommendations. The RNA was sent to the Australian Genome Research Facility Ltd. (http://www.agrf.org.au, Melbourne, Victoria, Australia) for labeling and hybridization to the Affymetrix Genechip® Cotton Genome Array (21,854 genes) (Affymetrix, http://www.affymetrix.com/). - 4 arrays - Cotton; x comparison between two genotypes in cell type This represents the gene expression component of the study only
