Transcriptome of galls formed by Meloidogyne javanica in Arabidopsis thaliana at 3 days post infection

Project description:The goal of this study is to compare the transcriptome profilling (RNA-seq) of galls (G) formed in Arabidopsis roots infected by Meloidogyne javanica at 3 days post infection compared to uninfected root segments (RC).

Transcription profiling of Arabidopsis thaliana ematode induced early giant cells and normalvascular root cells.

Project description:Giant cells (GCs)formed by meloidogyne javanica 3 days post infection were isolated by microaspiration from the Arabidopsis Col0 galls. Three independent biological replicates were used for hybridisation. The controls for comparisons were vascular cylinder tissues from uninfected root segments at equivalent positions to the galls in the infected roots. RNA extracted directly from either the controls or the GCs were amplified two times with a RNA polimerase linear amplification based approach

Down-regulation of gene expression is a conserved and distinctive feature required for early development of nematode-induced Giant Cells in tomato

Project description:Root-knot nematodes (RKN; Meloidogyne spp.) are sedentary parasites that affect a high variety of plants with a negative impact in the production of crops such as tomato. The infective RKN induces in the roots 4-7 highly specialized feeding cells (giant cells, GCs) developed into a hypertrophy cellular tissue or visible root swelling called “gall”. During GCs differentiation drastic alterations in genes expression occurs. However, information on genome-wide transcriptional profiles specifically in GCs is still lacking. With the aim to identify potential targets specifically regulated in GCs, we performed a temporal and spatial differential transcription profiling of tomato (Solanum lycopersicum), during the course of Meloidogyne javanica infection hybridizing TOM1 microarrays with hand-dissected galls at 1, 3, 7 and 14 days post-infection (dpi) and GCs exclusively isolated by LASER CAPTURE MICRODISSECTION (LCM) at 3 and 7 dpi. A GCs and galls comparison, at the same stage of development, reveals clear differences between their transcriptional patterns. For this purpose, a fast and efficient method to isolate LCM GCs from cryopreserved galls in the earliest differentiation state described to date: 48-72-hour post-infection (3 dpi), allowing good RNA preservation, was developed.

Interactions between root knot nematodes and potato

Project description:Plant-parasitic nematodes and especially the root-knot nematodes are ubiquitous pathogens. Eggs of root-knot nematodes (Meloidogyne javanica) were extracted from greenhouse cultures and second-stage juveniles (J2) were hatched in tap, sterile water on 30 µm sieves. Solanum tubersum cv. Desiree explants, i.e., stem including an axillary bud, were sectioned, under sterile conditions from in vitro growing seedlings and transferred to Magenta boxes containing Gamborg's media. Seedlings, 4 weeks post transferring to Gamborg's media were planted in pots containing autoclaved quartz sand. Three weeks later the plants were infected with 3000 M. javanica infective juveniles, applied to the soil in tap, sterile water. Control uninfected plants were mock-inoculated with tap, sterile water. Roots from 6 infected and 6 mock-inoculated plants were collected at a series of time points, including 5, 10 and 15 days post nematode infection/mock inoculation. Roots were observed under the microscope, and nematode feeding sites were selectively dissected, from young lateral roots. To control for the effect of tissue sectioning on gene expression, young lateral roots of the mock inoculated roots were dissected similarly to the infected roots, and collected. Dissected roots were snapped-freeze in liquid nitrogen and immediately stored in -80 C freezer. Total RNA was extracted using Qiagen RNAEasy kit. The experiment for each time point was duplicated, each duplicate derived from independent biological repeat. All RNA samples were amplified using the Ambion kit Message Amp catalog no. 1750, using as starting material 2.5 to 5 µg of total RNA. Keywords: Reference design
