root LOXN2 message is widespread in the cortex and endodermis of healthy roots, but specifically localized at high level in the cells bordering the nematode-induced syncytia of infected roots. In uninfected roots, the transcript is visualized in cortical and endodermal cells. In resistant infected roots, faint and infrequent signal spots are observed in the cortex, but LOXN2 message is abundant in the outer cells surrounding the vascular cylinder, in those cells injured by nematode penetration and those flanking the induced syncytia. In susceptible infected roots, the transcript is detected in cortical cells damaged by nematode invasion and undergoing necrosis, and in parenchymatous cells of the vascular cylinder strictly related to syncytia development Pisum sativum

Organism Comment Expression
Pisum sativum LOXN2 transcription is monitored in roots after mechanical injury and during nematode infection. The message peaks at 3 and 24 h after wounding in both genotypes and is more abundant in the resistant than in the susceptible pea. In nematode-infected roots, transcription of several LOX genes is triggered except LOXN2, which is repressed in both genotypes down
