Analysis of Rice Root Knot Nematode Diseases

Rice is one of the world's major food crops. Plant parasitic nematodes are one of the most essential soil-borne diseases in rice production. Currently, more than 300 species of nematodes from 35 genera have been reported to parasitize and cause harm to rice. Among them, rice root knot nematode (Meloidogyne graminicola) is the most serious plant parasitic nematode affecting rice yield. The rice root knot nematodes are widely distributed in tropical and subtropical areas, such as China, India, Bangladesh, Thailand, the United States, and other countries.

Lifeasible provides analysis of rice root knot nematode diseases to help our customers worldwide in the field of plant science. Our experts will answer your questions comprehensively and carefully and help you solve the problems in your studies. We guarantee satisfied and reliable results for our customers all over the world.

Pathogen Analysis of Rice Knot Nematode Diseases

• Rice root knot nematode disease is caused by the infection of root knot nematode J2 with the young root system of rice. The root tip of the affected rice is enlarged into a ball, and the root system is milky white and twisted, and coarse. When the damage is severe, a single root system has multiple root knots.

• Lifeasible provides nematode identification services, including morphological and molecular identification. In addition, we provide homology analysis of the pathogen, performed by sequencing analysis, BLAST tool, DNAMAN software, etc.

Analysis of Infection Characteristics

• Rice root-knot nematodes can harm upland rice, low-depression rice, irrigated rice, and deep-water rice and survive for a long time in the form of egg mass or larvae in flooded soil.
• We provide an analysis of infection characteristics, including larval infection characteristics, adult reinfection characteristics, and life history of rice root knot nematodes. Specifically, we help our clients study root knot size, color, number of nematodes invading the root, and direction of movement.

Analysis of Pathogenic Mechanism

• Pathogenicity of root-knot nematodes includes direct plant damage and indirect plant disease. We help our clients analyze the pathogenic mechanism of rice root knot nematode diseases.
• Mechanical damage is the most direct harm of root-knot nematodes to plants. We help study the role of related hydrolase secreted by nematodes to puncture and degradation of host root tip cells.
• When root-knot nematodes feed, the secretions of the esophagus glands are pathogenic substances, which is the main cause of plant damage. We assist in the analysis of various proteins in secretions, including β-1,4-endoglucanase, pectinate lyase, cellulose-binding protein, branch-acid mutase, calcium reticulin, dilatant protein, and microtubule tissue-binding protein.
• Root knot nematode infection of plants provides opportunities for infection of many pathogens. We help to study rice immune gene expression, hormone metabolism, biosynthesis-related genes and so on.
