New light shed on root lesion nematode

Plain text source: 
"I had always assumed, as had many other researchers, that nematodes ate into the roots, stunting their growth so that the plants could not reach water in the deeper soil," Dr Whish said... His research is finding that the root systems have developed almost normally and Dr Whish instead suspects the nematodes inflict their damage by penetrating the roots' outer layer and restricting their ability to transport water... "The nematodes penetrate the root, lay eggs inside the cortex of the roots and eventually the outer wall of root collapses causing the lesion and we believe this breaks the pipe that transports water to the plant," Dr Whish said...
