Plants respond similarly to signals from friends, enemies

...een plants and nematodes, even though the nematode provides no benefit to its host. Root-knot nematodes form feeding cells ?so-called giant cells ?in the plant and later galls or knots on it. "We don't know the precise structure of Nematode factor, but it appears that the nematodes may have actually acquired...

Research advances quest for HIV-1 vaccine
