Detection and Visualization of Specific Gene Transcripts by in situ RT-PCR in Nematode-Infected Arabidopsis Root Tissue
Author:  Krzysztof Wieczorek, date: 09/20/2015, view: 8936, Q&A: 0
This protocol describes an effective method of in situ RT-PCR that was developed to localize specific gene expression directly in thin cross-sections of nematode feeding sites induced by the cyst nematode Heterodera schachtii (H. ...
Infection Assay of Cyst Nematodes on Arabidopsis Roots
Authors:  Holger Bohlmann and Krzysztof Wieczorek, date: 09/20/2015, view: 10476, Q&A: 0
Plant parasitic nematodes are devastating pests on many crops. Juveniles (J2) of cyst nematodes invade the roots to induce a syncytium. This feeding site is their only source of nutrients. Male nematodes leave the roots after the fourth molt to mate ...

In situ Hybridization of Plant-parasitic Nematode Globodera pallida Juveniles to Detect Gene Expression
Authors:  Joanna Kud, Nejra Solo, Allan Caplan, Joseph C. Kuhl, Louise-Marie Dandurand and Fangming Xiao, date: 09/20/2019, view: 3352, Q&A: 0
In this study, we describe a standard whole mount in situ hybridization method which is used to determine the spatial-temporal expression pattern of genes from Globodera spp. Unlike more invasive radioactive labeling approaches, ...

Root-knot Nematode Penetration and Sclareol Nematicidal Activity Assays
Authors:  Taketo Fujimoto, Takayuki Mizukubo, Hiroshi Abe and Shigemi Seo, date: 06/20/2016, view: 9197, Q&A: 0
Plant parasitic nematodes parasitize roots and/or stems of various plants thereby inhibiting absorption of nutrients and moisture. In particular, root-knot nematodes (RKN) are a group of the most devastating pests. Various techniques, such as soil ...
