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

ABSTRACT: 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.

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.

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.

Cotton (Gossypium hirsutum L.) root transcriptional response to the southern Root-Knot Nematode (RKN) Meloidogyne incognita infestation

Project description:As an initial step to explore the cotton (Gossypium hirsutum L.) root transcriptional response to the southern Root-Knot Nematode (RKN) Meloidogyne incognita infestation, conventional heirloom G. hirsutum (Gh) cultivars [susceptible Acala SJ-2 (SJ2), moderately resistant Upland Wild Mexico Jack Jones (WMJJ), and resistant Acala NemX] that have been shown to be useful as an informative genetic model for detecting and introgressing RKN resistance genes into commercial Upland cotton were used to enlighten the molecular mechanisms and gene expression of RKN resistance. Using the next generation sequencing (NGS) Illumina MiSeq and HiSeq, we performed RNA-seq profiling in roots with disease progression of 10 days and collected from 23 days old plants of SJ2, WMJJ, and NemX. With three biological replicates of each treatment from each cultivar, plants were subjected to RKN-infestation and non-infested control developing a total of 18 RNA-seq libraries

Below ground attack by root knot nematode Meloidogyne graminicola predisposes rice to blast disease

Project description:Magnaporthe oryzae (rice blast) and the root-knot nematode Meloidogyne graminicola are causing two of the most important pathogenic diseases jeopardizing rice production. Here, we show that root-knot nematode infestation on rice roots leads to important above-ground changes in plant immunity gene expression, which is correlated with significantly enhanced susceptibility to blast disease.

MELOHOSTRACE: Whole genome polymorphism across Meloidogyne incognita isolates showing different biological traits

Project description:High-coverage whole genome sequencing of 11 Brazilian isolates of the root-knot nematode Meloidogyne incognita, presenting different host plant preferences and different geographical origins. Four M. incognita host races had been proposed in the past, based on host (in)compatibility on four different plant strains. The objective was to assess whether genomic variations (SNP) correlate with host range compatibility, geographical origin and host plant of origin.

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

Project description: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.
