Abstract

Juvenile development of the cereal cyst nematode (Heterodera avenae Woll.), and the anatomy and ultrastructure of nematode-induced syncytiain wheat (Triticum aestivum L.) were studied using the near isogenic lines Prins (susceptible) and AUS 10894 x Prins (resistant). After synchronised inoculation, male development proceeded to completion in both cultivars, while female development was arrested at the fourth stagein the resistant cultivar. Syncytia were initiated in both cultivars by day four, and their development appeared similar until day fifteen. At this stage syncytia in the susceptible cultivar became highly active in appearance, vacuoles decreased in size, and an increased volume of cytoplasm had numerous organelles. Syncytia in the resistant cultivar at day fifteen were dominated by coalescing large vacuoles, with reduced cytoplasm. By day 33 syncytial cytoplasm was completely degenerate. Endodermal necrosis was observed in both cultivars. The timing of cellular responses is discussed.
