Root-knot nematodes.

2006
This chapter covers the life cycle, behaviour, survival, cytogenetics, general morphology, post-infection development, and management and control (through cultural, physical, chemical and biological methods, and crop resistance) of root-knot nematodes (Meloidogyne arenaria, M. artiella, M. chitwoodi, M. exigua, M. fallax, M. graminicola, M.

Ultrastructure of a neurosensory organ in a root-knot nematode

Journal of Ultrastructure Research, 1976
Second stage larvae of the root-knot nematode, Meloidogyne incognita [(Kofoid and White) Chitwood], were examined to elucidate the ultrastructure of the amphids, which are paired lateral organs believed to function in chemosensory perception. The amphids were found to consist of supportive, nervous, and secretory tissues.

The interaction of SO2 and root-knot nematode on tomato

Environmental Pollution, 1993
Intermittent exposure of tomato plants (cv. Pusa Ruby) to SO(2) at 286 microg m(-3) (3 h every heavy third day for 75 days) induced slight chlorosis of leaves. At 571 microg m(-3), considerable chlorosis with browning developed on the foliage. These symptoms were more pronounced and appeared earlier on SO(2)-exposed plants infected with Meloidogyne ...

Detection of Root Knot Nematodes in Microscopy Images

Proceedings of the International Conference on Bioimaging, 2015
Object detection in microscopy image is essential for further analysis in many applications. However, images are not always easy to analyze due to uneven illumination and noise. In addition, objects may appear merged together with debris. This work presents a method for detecting rice root knot nematodes in microscopy images.

Plant-cyst nematode and plant-root-knot nematode interactions

Parasitology Today, 1994
Root-knot nematodes and cyst nematodes are obligate plant parasites that cause extensive damage to the agriculture of both temperate and tropical countries. In this review, Andreas Niebel, Godelieve Gheysen and Marc Van Montagu describe how, in the past decade, the use of molecular techniques has provided new insights in the complex interactions ...

The Root-Knot Nematode.

The Papua New Guinea Journal of Agriculture, Forestry and Fisheries
Nematodes, or eelworms, are a group of semi-microscopic animals, some of which are parasitic on plants or other animals, others may be free-living.

Root-Knot Nematodes of Paulownia and Their Management

Indian Journal of Forestry, 1999
Studies on root-knot nematodes of Paulownia fortunei and P. tomentosa were undertaken both in the nursery and experimental plots at New Forest, Dehra Dun. Both Paulownia spp. were found susceptible to root-knot nematodes which were identified as M. incognita and M. javanica of which the latter was predominent.

Resistance to Root-Knot Nematodes in Tomato

1997
Host resistance to three major species of root-knot nematodes, Meloidogyne incognita, M. javanica and M. arenaria, has been introgressed in the cultivated tomato (Lycopersicon esculentum Mill.) from its wild relative L. peruvianum. The trait is dominant and has been located at a single locus, Mi-1, on chromosome 6.

Root-knot Nematodes and Giant Cells

2011
Of all the economically important plant parasitic nematodes, root-knot nematodes (Meloidogyne species) are amongst the most widespread, the best recognized and most widely studied. This is partly because infected roots develop galls where the nematodes feed, which with severe infection give roots a ‘knotted’ appearance. They have a remarkably wide host

Molecular Techniques for Root-Knot Nematode Identification

Among plant-parasitic nematodes, root-knot nematodes (RKN), Meloidogyne spp., are the most important parasite infecting economically important crops globally and causing severe losses in crop production. The use of efficient nematode control methods against these parasites depends upon their correct detection in roots and soil samples.
