We wondered whether resistance to nematodes might also involve PTI and the likely requirement for the master PTI regulator SERK3. To address this, we infected tomato plants silenced for SlSERK3A or SlSERK3B with Meloidogyne incognita infective-stage juveniles and evaluated the roots for nematode infection and reproduction. Here, SERPINB6 is linked to Nematoda infectious disease.
