Project description:Jeffersonia diphylla, which belongs to Berberidaceae, is a perennial herb native to North America. In the present study, we determined the first plastome of J. diphylla using genome skimming approach. The pastome of J. diphylla is 152,842 bp in length, with a large single copy region (LSC) of 82,266 bp and a small single copy region (SSC) of 19,284 bp separated by a pair of inverted repeats (IRs) of 25,646 bp. It encodes 113 unique genes, consisting of 79 protein-coding genes, 30 tRNA genes, and four rRNA genes, with 19 duplicated genes in the IR regions. Phylogenetic analysis indicates that J. diphylla is sister to Plagiorhegma dubium, subsequently is sister to a clade including Diphylleia, Sinopodophyllum, Podophyllum, Dysosma, Achlys, and Epimedium.
Project description:Co-expression networks and gene regulatory networks (GRNs) are emerging as important tools for predicting the functional roles of individual genes at a system-wide scale. To enable network reconstructions we built a large-scale gene expression atlas comprised of 62,547 mRNAs, 17,862 non-modified proteins, and 6,227 phosphoproteins harboring 31,595 phosphorylation sites quantified across maize development. There was little edge conservation in co-expression and GRNs reconstructed using transcriptome versus proteome data yet networks from either data type were enriched in ontological categories and effective in predicting known regulatory relationships. This integrated gene expression atlas provides a valuable community resource. The networks should facilitate plant biology research and they provide a conceptual framework for future systems biology studies highlighting the importance of studying gene regulation at several levels.
