Project description:Here we performed a transcriptomic study on PaWB phytoplasma-infected Paulownia sp. using Solexa/IlluminaM-bM-^@M-^Ys high-throughput digital gene expression (DGE) system. 4 DGE libraries (from 2 virus-infected samples and 2 healthy samples) were constructed, and the gene expression variations between the PaWB phytoplasma-infected (diseased) sample and the corresponding healthy sample were compared. Thousands of differentially expressed genes were obtained by the comparison, and KEGG pathway analysis of these genes suggested that many biological processes were responded to PaWB infection. To investigate the response of Paulownia sp. to PaWB infection, we collected four samples in two groups, namely the tissue cultured group (containing healthy sample TH and diseased sample TD) and field-grown group (containing healthy sample FH and diseased sample FD). Four individual tag libraries from these samples were constructed in parallel. For the gene expression analysis, the digital gene expression (DGE) data of diseased sample were compared to that of healthy sample in each group to obtain the gene expression variations.

Project description:Analysis of Paulownia tomentosa cambial tissues at gene expression level. The hypothesis tested in the present study was that miRNAs can regulate the development of the vascular cambium.The results provide new insights into the important regulatory functions of miRNAs in vascular cambium development and wood formation in conifers.

Project description:Lysine acetylation and succinylation are post-translational modifications of proteins, and have been shown to play roles in plant response to pathogen infection. Phytoplasma infection can directly alter multiple metabolic processes in Paulownia and lead to Paulownia witches’ broom (PaWB), the major cause of Paulownia mortality worldwide. To explore the extent and function of lysine acylations during phytoplasma infection, we investigated global proteome, acetylome, and succinylome of phytoplasma-infected Paulownia tomentosa seedlings. In total, we globally yield 8963 proteins, 2893 acetylated, and 1271 succinylated proteins. Among them, 425 substrates were simultaneously acetylated and succinylated. Comparative analysis revealed that 276 proteins, 546 acetylated proteins and 5 succinylated proteins were associated with PaWB. Our results suggested that acetylation may be more important than succinylation in response to phytoplasma infection. Enzymatic assays showed that acetylation modified the activities of protochlorophyllide reductase and RuBisCO in phytoplasma-infected seedlings. On the basis of these results, a model to elucidate the molecular mechanism responses to PaWB was proposed and this research offer a resource for functional studies on the effects of acetylation on protein function.

Project description:Genome and transcriptome assembly data often contain DNA and RNA contaminations from external organisms, introduced during nucleotide extraction or sequencing. In this study, contamination of seed plant (Spermatophyta) transcriptomes/genomes with p25alpha domain encoding RNA/DNA was systematically investigated. This domain only occurs in organisms possessing a eukaryotic flagellum (cilium), which seed plants usually do not have. Nucleotide sequences available at the National Center for Biotechnology Information website, including transcriptome shotgun assemblies (TSAs), whole-genome shotgun contigs (WGSs), and expressed sequence tags (ESTs), were searched for sequences containing a p25alpha domain in Spermatophyta. Despite the lack of proteins containing the p25alpha domain, such fragments or complete mRNAs in some EST and TSA databases were found. A phylogenetic analysis showed that these were contaminations whose possible sources were microorganisms (flagellated fungi, protists) and arthropods/worms; however, there were cases where it cannot be excluded that the sequences found were genuine hits and not of external origin.
