'Bois noir' phytoplasma induces significant reprogramming of the leaf transcriptome in the field grown grapevine

ABSTRACT: Transcriptional profiling of Vitis vinifera cv. Chardonnay healthy vs. Phytoplasma-infected plants (Bois noir phytoplasma). Study was conducted on grapevine plants grown in the same vineyard (leaf midribs were sampled). Keywords: disease state analysis Two-condition experiment: healthy vs. infected plants/shoots. Biological replicates: 4 healthy, 4 infected. No replicates. Each sample was prepared as a pool of several samples (each sample was collected from a different shoots/plants) of the same disease status. Each sample was co-hybridized to a common reference cRNA (pool of all samples).

ORGANISM(S): Vitis vinifera

'Bois noir' phytoplasma induces significant reprogramming of the leaf transcriptome in the field grown grapevine.

BMC genomics 20091002

<h4>Background</h4>Phytoplasmas are bacteria without cell walls from the class Mollicutes. They are obligate intracellular plant pathogens which cause diseases in hundreds of economically important plants including the grapevine (Vitis vinifera). Knowledge of their biology and the mechanisms of their interactions with hosts is largely unknown because they are uncultivable and experimentally inaccessible in their hosts. We detail here the global transcriptional profiling in grapevine responses to ...[more]

Small RNA profiling of aster yellows infected Catharanthus roseus plants

Project description:Aster yellows phytoplasma strain Hyd35 (16SrI-B) in micropropagated periwinkle shoots in collection was used to produce infected plants in pots that were separated according to the diverse symptomatology i.e. phyllody and witches’ broom. Small RNA high-throughput sequencing (HTS) was then used to determine the small RNA pattern of these plants. Bioinformatics analysis revealed the presence of expression changes of different miRNA classes and the presence of phytoplasma derived small RNAs. These results could complement previous studies and serve as a starting point for small RNA omics in phytoplasma research

Phytoplasma-responsive small RNAs in Mexican lime trees

Project description:Background: Witches’ broom disease of Mexican lime (Citrus aurantifolia L.), which is caused by the phytoplasma “Candidatus Phytoplasma aurantifolia”, is a devastating disease that results in significant economic losses. Plants adapt to abiotic stresses by regulating gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) are a recently identified family of molecules that regulate plant responses to environmental stresses through post-transcriptional gene silencing. Methods: Using a high-throughput approach to sequence small RNAs, we compared the expression profiles of miRNAs in healthy Mexican lime trees and in plants infected with “Ca. Phytoplasma aurantifolia”. Results: Our results demonstrated the involvement of different miRNAs in the response of Mexican lime trees to infection by “Ca. Phytoplasma aurantifolia”. We identified miRNA families that are expressed differentially upon infection with phytoplasmas. Most of the miRNAs had variants with small sequence variations (isomiRs), which are expressed differentially in response to pathogen infection. Conclusions: It is likely that the miRNAs that are expressed differentially in healthy and phytoplasma-infected Mexican lime trees are involved in coordinating the regulation of hormonal, nutritional, and stress signalling pathways, and the complex interactions between them. Future research to elucidate the roles of these miRNAs should improve our understanding of the level of diversity of specific plant responses to phytoplasmas.

Digital gene expression (DGE) of PaWB phytoplasma-infected Paulownia witches

Project description:Here we performed a transcriptomic study on PaWB phytoplasma-infected Paulownia sp. using Solexa/Illumina’s 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.

A microarray analysis highlights the role of tetrapyrrole pathways in grapevine responses to stolbur phytoplasma, phloem virus infections and recovered status

Project description:Several systemic diseases affect Vitis vinifera worldwide with important consequent management costs. Phytoplasma and viruses represent the most detrimental pathogens inducing symptoms and metabolic alterations that modify quantitatively the crop production. In the aim to investigate the plant/pathogen interactions, different grapevine samples, naturally affected (in mixed or single infections) by Stolbur phytoplasma (agent of Bois Noir disease) and viruses, in comparison to healthy and recovered controls, to identify the plant response to systemic pathogen infection. The preliminary results showed that expression levels of thousands of genes were altered in infected plants, involving various metabolic pathways.
