Evidence for the growth of Plasmodiophora brassicae in vitro (1996)
Journal Article

Plasmodiophora brassicae is a root-invading pathogen that causes club root disease of brassica crops. Although generally regarded as an obligate biotroph, a number of reports over the last century have suggested that the organism may have a free livi...

Somaclonal variation in watercress for resistance to crook root disease (1995)
Journal Article

Watercress (Rorippa nasturtium-aquaticum) shoots were regenerated from callus initiated from petioles on a range of media. The best coefficient of regeneration was obtained when callus was induced on a medium containing 0.25 mgl-1 thidiazuron and 0.0...

The effects of temperature on zoospores of the crook root fungus Spongospora subterranea f.sp. nasturtii (1995)
Journal Article

The effect of temperature on the release, survival, encystment and infectivity of Spongospora subterranea f.sp. nasturtii zoospores released from diseased watercress roots was studied. There was rapid, synchronized release of zoospores at 20°C follow... Read More about The effects of temperature on zoospores of the crook root fungus Spongospora subterranea f.sp. nasturtii.

Development and Evaluation of a Laboratory‐Based Technique for Screening Somaclonal Regenerants of Watercress (Rorippanasturtium‐aquatium) for Resistance to Crook Root Disease (Spongospora subterranea f. sp. nasturtii) (1994)
Journal Article

A laboratory based method has been developed for infecting watercress with the crook root fungus (Spongospora subterranea f.sp. nasturtii). This utilised plastic trays of nutrient solution on which watercress shoots, supported by floats, were grown f...
