Project description:We conducted the genome-wide lncRNA and mRNA expression profiling using RNA samples extracted from rat incisor enamel organs, so as to refine the number of predicted gene targets for lncRNA regulators.
Project description:Chrysanthemum is a garden plant with good economic benefit and high ornamental value. Chrysanthemum in the key period of flowering in autumn and winter, vulnerable to cold damage, affecting the normal growth of the chrysanthemum plant and even death. little is known regarding the study of histone crotonylation in plant cold response. In this study, we first obtained reference chrysanthemum transcriptome data via RNA sequencing. Next, we quantitatively investigated the chrysanthemum proteome, crotonylation, and the association between them in chrysanthemum following low temperature. In total, 365669 unigenes, 6693 proteins and 2017 crotonylation sites were quantified under low temperature stress. There were 24631 up-regulated and 22648 down-regulated unigenes (absolute log2-fold change > 1 and P value<0.05), 393 up-regulated and 500 down-regulated proteins using a 1.2-fold threshold (P<0.05). The lysine crotonylation mainly influenced in photosynthesis, ribosome, antioxidant enzyme and ROS system. In the process of low temperature, 61 lysine crotonylation sites in 89 proteins were up-regulated and 87 lysine crotonylation sites in 72 proteins are down-regulated (1.2-fold threshold, P<0.05).

Project description:DNA methylation is an epigenetic modification that differs between plant organs and tissues, but the extent of variation between cell types is not known. Here, we report single-base resolution whole genome DNA methylomes, mRNA transcriptomes, and small RNA transcriptomes for six cell populations covering the major cell types of the Arabidopsis root meristem. We identify widespread cell type specific patterns of DNA methylation, especially in the CHH sequence context. The genome of the columella root cap is the most highly methylated Arabidopsis cell characterized to date. It is hypermethylated within transposable elements, accompanied by increased abundance of transcripts encoding RNA-directed DNA methylation (RdDM) pathway components and 24 nt small RNAs. Absence of the nucleosome remodeler DECREASED DNA METHYLATION 1, required for maintenance of DNA methylation, and low abundance of histone transcripts involved in heterochromatin formation suggests a loss of heterochromatin may occur in the columella, thus allowing access of RdDM factors to the whole genome, and producing excess 24 nt small RNAs in this tissue. Together, these maps provide new insights into the epigenomic diversity that exists between distinct plant somatic cell types. MethylC-seq from six cell populations covering the major cell types of the Arabidopsis root meristem.
Project description:Gene expression analysis of chrysanthemum infected with three different viruses including Cucumber mosaic virus, Tomato spotted wilt virus, and Potato virus X have been performed using the chrysanthemum 135K microarray. Mock and each virus infected chrysanthemum plants were subjected for microarray analysis.
