The nematodes are transmitted plant to plant by splashing, overhead irrigation, rainfall, and other forms of dripping water. They can also be ...
They exist in soil in areas with hot climates or short winters. About 2000 species of plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. [1] Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and ...
Tylenchidae is a family of nematodes. They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples. [2] They diverged relatively early on and many species pose little risk to economically important plant species. [2]
Nematodes play an astoundingly wide range of ecological roles that scientists are only beginning to understand. Word from the Smokies: Scientist uncovers secret life of soil through study of nematodes
Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and beneficial soil fauna. The golden nematode Globodera rostochiensis is a particularly harmful pest that has resulted in quarantines and crop failures worldwide.
Caenorhabditis elegans (/ ˌ s iː n oʊ r æ b ˈ d aɪ t ə s ˈ ɛ l ə ɡ æ n s / [6]) is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments.
