(Submitter supplied) Cytosine methylation is an important mechanism for dynamical regulation of gene expression and transposon mobility during plant developmental processes. Recently, the variation of DNA methylation has been described between wild type and DNA methylation-related mutants in Arabidopsis thaliana. However, the elaborate representation of soybean DNA methylomes remains lacking. Here, we described the epigenome maps of soybean root, stem, leaf, and cotyledon of developing seed at a single-base resolution. more...

(Submitter supplied) Epigenetic modification plays important roles in plant and animal development. DNA methylation can impact the transposable element (TE) silencing, gene imprinting and regulate gene expression.Through a genome-wide analysis, DNA methylation peaks were respectively characterized and mapped in maize embryo and endosperm genome. Distinct methylation level across maize embryo and endosperm was observed. The maize embryo genome contained more DNA methylation peaks than endosperm. However, the endosperm chloroplast genome contained more DNA methylation peaks to compare with the embryo chloroplast genome. DNA methylation regions were characterized and mapped in genome. More CG island (CGI) shore are methylated than CGI in maize suggested that DNA methylation level is not positively correlated with CpG density. The DNA methylation occurred more frequently in the promoter sequence and transcriptional termination region (TTR) than other regions of the genes. The result showed that 99% TEs we characterized are methylated in maize embryo, but some (34.8%) of them are not methylated in endosperm. Maize embryo and endosperm exhibit distinct pattern/level of methylation. The most differentially methylated two regions between embryo and endosperm are High CpG content promoters (HCPs) and high CpG content TTRs (HCTTRs). DNA methylation peaks distinction of mitochondria and chloroplast DNA were less than the nucleus DNA. Our results indicated that DNA methylation is associated with the gene silencing or gene activation in maize endosperm and embryo. Many genes involved in embryogenesis and seed development were found differentially methylated in embryo and endosperm. We found 17 endosperm-specific expressed imprinting genes were hypomethylated in endosperm and were hypermethylated in embryo. The expression of a maize DEMETER -like (DME-like) gene and MBD101 gene (MBD4 homolog) which direct bulk genome DNA demethylation were higher in endosperm than in embryo. These two genes may be associated with the distinct methylation level across maize embryo and endosperm.The methylomes of maize embryo and endosperm was obtained by MeDIP-seq method. The global mapping of maize embryo and endosperm methylation in this study broadened our knowledge of DNA methylation patterns in maize genome, and provided useful information for future studies on maize seed development and regulation of metabolic pathways in different seed tissues.

(Submitter supplied) Chromatin modifications, such as cytosine methylation of DNA, play a significant role in mediating gene expression in plants, which affects growth, development, and cell differentiation. Since root hairs are single cell extensions of the root epidermis and the primary organs for water uptake and nutrients, we sought to use root hairs as a single cell model system to measure the impact of environmental stress. more...

(Submitter supplied) Eukaryotic cytosine methylation represses transposable elements, but also occurs in bodies of active genes. The extent to which these processes are conserved is unclear, and little is known about methylation outside of mammals, Arabidopsis thaliana, and Neurospora crassa. Utilizing deep bisulfite sequencing, we have quantified DNA methylation in five plant, seven animal, and five fungal genomes. We find that gene body methylation is conserved between plants and animals, whereas selective methylation of transposons has evolved independently in the vertebrate lineage. more...

(Submitter supplied) To explore the effect of stable RNAi on the small RNA (sRNA) population in wheat, we constructed a sRNA library from hexaploid wheat that expresses an RNAi construct under the 35S promoter that targets the endogenous NO APICAL MERISTEM (TaNAM) gene. The presence of this RNAi transgene causes a 40% reduction in expression of the target genes as measured by quantitative RT-PCR and significantly delays senescence and reduces remobilization of N, Fe, and Zn to the grain.

(Submitter supplied) Somatic variation is a valuable source of trait diversity in clonally propagated crops. In grapevine, which has been clonally propagated worldwide for centuries, important phenotypes such as white berry colour are the result of genetic changes caused by transposable elements. Additionally, epiallele formation may play a role in determining geo-specific (‘terroir’) differences in grapes and thus ultimately in wine. more...

(Submitter supplied) We uncover distinct DNA methylation dynamics over genes and repeat sequences during early plant life in Arabidopsis. While gene body methylation, which is restricted to CG sites and concerns 20-30% of all genes is detected at all stages examined, it typically fluctuates over a few CGs, with no coherent pattern. In contrast, transposable elements and their relics as well as other repeat sequences, have consistently high methylation levels at CGs and show increasing CHG and especially CHH methylation during embryogenesis. more...

Cotyledon mutants are important for the genetic dissection of embryo patterning and seed development.Here, we characterised a soybean curled-cotyledon (cco) mutant. Compared with wild-type (WT), the entire embryos of cco mutant resembled the “tail of swallow”. more...
