RNA-seq of Arabidopsis thaliana Col-0 and opr2-1 mutants over four timepoints and (mock)infection with Meloidogyne incognita

ABSTRACT: We compared the gene expression of wild-type Col-0 and a T-DNA mutant SALK_116381C (opr2-1). We either infected or mock-infected the plants with the root knot nematode Meloidogyne incognita and measured the root transcriptome after 0, 1, 4, and 7 days post infection using RNA-seq. The aim of the experiment was to determine whether opr2-1 affected gene expression patterns induced by nematode infection.

The aim of the experiment was to determine whether the tcp mutatants affected gene expression patterns induced by nematode infection.

RNA-seq of roots of ten genotypes of Solanum lycopersicum infected with Meloidogyne incognita over six time-points

Project description:In this experiment we measured the transcriptional response of ten tomato cultivars when infected by the plant-parasitic nematode M. incognita. The ten cultivars showed differential levels of susceptibility to M. incognita infection. Ten-days old plants were exposed to nematodes and harvested 1, 2, 3, 4, 7, or 10 days post infection. Galls or representative uninfected tissues were harvested and used for RNA sequencing. The data was used to investigate the link between susceptibility to M. incognita infection and gene expression in tomato.

RNAseq of leaves of tomato plants infected with a combination of four below- and above ground pathogens

Project description:In this experiment we measured the transcriptional response of tomato plants (cv “Money maker”) when attacked belowground by the nematode M. inognita and, subsequently, aboveground by different (and common for this crop) biotic agents. Three weeks-old plants were exposed to nematodes for 5 days. At the fifth day the terminal leaflet of one of the first two true leaves was infected with the Cauliflower Mosaic Virus, or with the pathogen, or with the potato aphid Macrosiphum euphorbiae, or with the CMV-infected M. euphorbiae. For each belowground/aboveground combination treatment a set of control plants that received only the aboveground treatment was prepared. The infected leaflets of 5 biological replicates, each consisting of 1 plant, were collected 1, 2, 3, 4, 5 and 6 days after the onset of the aboveground treatment and flash frozen in liquid nitrogen. A different set of plants was used for every time point. Corresponding leaves from plants that did not receive any aboveground treatment (control) were selected and sampled as described above. Three biological replicates were selected among the five for RNA isolation. Total RNA was sent for sequencing to BGI Hong Kong.

Expression data from LCM-captured Arabidopsis root cells after challenge with Meloidogyne incognita

Project description:The differentiation of specialized feeding sites in Arabidopsis root cells in response to nematode infestation involves substantial cellular reprogramming of host cells that is not well characterized at the molecular level. Expression data was generated from Arabidopsis root cells undergoing giant cell formation due to nematode infestation and from non-infested control root cells. Cells were laser captured 14 and 21 days after infestation. Samples, collected 14 days post infestation, consisted of three biological replicates per treatment (control root cells or giant cells). RNA samples were isolated from ~150 control cells or from ~80 giant cells using the PicoPure RNA Isolation Kit (Arcturus, Mountain View, USA). RNA amplifications were carried out with the NuGEN WT-Ovation Pico kit. GSM546568-GSM546577: Control and giant cells collected 21 days post infestation.

Transcriptional reprogramming by root knot and migratory nematode infection in rice

Project description:In this study a comparison was made between the local transcriptional changes at two time points upon root knot (Meloidogyne graminicola) and migratory nematode (Hirschmanniella oryzae) infection in rice. Using mRNA-Seq we have characterized specific and general responses of the root challenged with these endoparastic root nematodes with very different modes of action. Root knot nematodes induce major developmental reprogramming of the root tip, where they force the cortical cells to form multinucleate giant cells, resulting in gall-development. Our results show that root knot nematodes force the plant to produce and transfer nutrients, like sugars and amino acids, to this tissue. Migratory nematodes, on the other hand, induce the expression of proteins involved in plant death and oxidative stress, and obstruct the normal metabolic activity of the root. While migratory nematode infection also causes upregulation of biotic stress-related genes early in the infection, the root knot nematodes seem to actively suppress the local defence of the plant root. This is exemplified by a downregulation of genes involved in the salicylic acid and ethylene pathways. Interestingly, hormone pathways usually involved in plant development, were strongly induced (auxin and gibberellin) or repressed (cytokinin) in the galls. In addition, thousands of novel transcriptionally active regions as well as highly expressed nematode transcripts were detected in the infected root tissues. These results uncover previously unrecognized nematode-specific expression profiles and provide an interesting starting point to study the physiological function of many yet unannotated transcripts potentially targeted by these nematodes. 2 or 3 biological replicates of nematode infected roots and root tips and their respective controls were sampled at two time points (1 biological replicate contains pooled tissue from 6 plants)

Expression data from LCM-captured Zea mays root cells after challenge with Meloidogyne incognita

Project description:The differentiation of specialized feeding sites in Zea mays root cells in response to nematode infestation involves substantial cellular reprogramming of host cells that is not well characterized at the molecular level. Expression data was generated from Zea mays root cells undergoing giant cell formation due to nematode infestation and from non-infested control root cells. Cells were laser captured 14 and 21 days after infestation. Each time point (14 day and 21 day) consisted of three biological replicates per treatment (control root cells or giant cells). Control cells were captured from an area ~13,000,000 um2 in size and giant cells were captured from an area ~5,000,000 um2 in size. RNA samples were isolated using the PicoPure RNA Isolation Kit (Arcturus, Mountain View, USA). RNA amplifications were carried out with the NuGEN WT-Ovation Pico kit.

Total RNA RNAseq from roots of Arabidopsis Col-0 and siz1-2, infected and non-infected with Heterodera schachtii

Project description:In this experiment we evaluate the transcriptional response to beet cyst nematode infection in wild-type (Col-0) and siz1 a knocked-down Arabidopsis thaliana (siz1-2). The data indicates that the mutation in siz1-2 leads to a strong transcriptional regulation in the plant, mostly of genes related to plant defense. The interaction of the mutation and infection by H. schachtii results in differential regulation of a small subset of genes. Samples were taken from whole root systems of mock or H. schahtii-infected 21 day-old seedlings (7 days post-infection). Each sample contained at least 18 plants and 3 biological replicates of each sample were collected.

Microarray from roots of Arabidopsis Col-0 and knock-down UPL3, infected and non-infected with Heterodera schachtii

Project description:In this experiment we evaluate the transcriptional response to beet cyst nematode infection in wild-type (Col-0) and a upl3 knocked-down Arabidopsis thaliana. The data indicates that the upl3 knock-down alone does not induce a strong transcriptional regulation in the plant. However, the interaction of the mutation and infection by H. schachtii results in a strong transcriptional differential regulation, likely involving the plant’s immune responses. Samples were taken from whole root systems of 14 day-old seedlings (0 days post-infection) and mock or H. schahtii-infected 21 day-old seedlings (7 days post-infection). Each sample contained at least 18 plants and 4 biological replicates of each sample were collected.
