NOX5 and infection: The Nox5 gene had a notably high transcript level in the laid eggs at a particular time point (0 h) and rapidly decreased levels at 24 h after egg-laying in rice leaf sheaths, implicating a possibility that Nox5-generated ROS are required for oviposition of mature oocytes from the ovipositor to rice tissue and for the survival of freshly laid eggs to overcome new environmental challenges, i.e., defenses from plant hosts and pathogenic infection.
