Mechanism Analysis of Plant Resistance Genes to Nematode Infection

Plant nematodes are an essential group of pathogenic organisms that cause serious damage to agricultural production and significant losses to crop yields worldwide. Plant-resistant genes play an important role in the response of plants, and the discovery of nematode-resistant genes and the development of nematode-resistant varieties is an effective way to control nematode diseases. The localization and cloning of nematode-resistant genes have significantly contributed to elucidating the molecular mechanism of nematode resistance in plants.

Lifeasible makes full use of our specialized libraries, selection strategies, and maturation techniques to optimize the stability and performance of plant science. With advanced technology and experienced staff, we provide analysis services for plant resistance genes to nematode infection to global clients.

Analysis of Nematode-Resistant Genes in Plants

• To avoid environmental pollution by chemicals, the selection of nematode-resistant varieties is becoming increasingly important, and it is of utmost importance to study the resistance genes and their intrinsic resistance mechanisms.
• Lifeasible provides analysis of nematode-resistant genes in beets, such as Hs, that is a single dominant gene with resistance to the beet cyst nematode. We offer services to locate resistance genes in potatoes, including Gpa, Gpa5, Grp1, GroVI and H1, and others, which are resistant to potato cyst nematode.

• Cultivated tomatoes are one of the more nematode-sensitive vegetable crops, and we help our clients to identify several nematode-resistant genes in tomatoes, such as Mi-1, Hero, Mi3, Mi5, Mi-9, etc. We also provide services for exploring genes resistance to soybean cyst nematode, including rhg1, rhg2, rhg3, Rhg4, rhg5, and so on. In addition, some resistant genes for cereal cyst nematode are also in our service lists.

Mechanism Analysis of Nematode-Resistance Genes

• Plant resistance to nematodes can be divided into two categories. The first type of resistance is characterized by an allergic reaction to cells at the feeding site within 5 d of nematode infestation, with necrosis of cells. The second type of resistance is the degradation of cells at the feeding sites during the later stages of nematode infestation, but no allergic reactions occur.
• We provide mechanism analysis of nematode-resistance genes, including plant-nematode affinity interactions, non-affinity interactions, activation of resistance responses by nematode-resistant genes, specificity of nematode-resistant genes, identification of nematode-free gene products, induction of systemic resistance, and so on.
