Meloidogyne incognita (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of parasitism.
M. incognita can move along shallower temperature gradients (0.001 °C/cm) than any other known organism,[1] an example of thermotaxis. The response is complicated and thought to allow the nematodes to move toward an appropriate level in soil,[2] while they search for chemical cues that can guide them to specific roots.[3][4][5]
