Aphanomyces zoospores

The characteristic behavior of Aphanomyces zoospore movement is shown in Fig. 6, where zoospore movement is inhibited in the area close to a Chromosorb W AW particle treated with a mixture of the stimulant and repellent factors from roots of P. oleracea, whilst in area remote from the... [Pg.1080]

Antialgal activity, termed zoosporicidal activity or antagonism to the asexual spores of certain algae and fungi, for example of the phytopathenogenic organism, Aphanomyces cochliodes by anacardic acids from unripe Ginkgo biloba fruit has been studied [18] and found to lead to motility inhibition and lysis of the zoospores. [Pg.153]

Twelve flavones (1, 6,10, 53-55, 57-59, 77-79) including cochliophilin A (6), and a chromone (64), were chemically prepared in order to compare their attractant effects on zoospores of Aphanomyces cochlioides. [Pg.495]

Cochliophilin A (6) has previously been isolated from sugar beet roots infected with the basidiomycete fungus Rhizoctonia solani (Thanatephorus cucumeris) [9]. However, it is not yet known if this compound occurs in healthy, uninfected roots of sugar beet, nor if it has any attractant effect on the hyphae of R. solani, a fungus that is only distantly related to the zoospore-producing species of Aphanomyces. As A. cochlioides may cause... [Pg.499]

We thank Professors R. Yokosawa, F. Tomita, and M. Fujimura for kindly supplying the fungal strains, Aphanomyces cochlioides, Cladosporium herbarum, and Neurospora crassa, respectively. Much of the research on which this review is based, has been carried out by the following students, Masters Y. Matsukura, N. Toda, and H. Katsuta (benzimidazole antidotes), and by Dr. T. Horio Masters T. Takayama, H. Kikuchi, K. Ohkawa, and M. Mizutani (zoospore attractants). [Pg.502]
