Islam, Tofazzal Md. published the artcileInterruption of the homing events of phytopathogenic Aphanomyces cochlioides zoospores by secondary metabolites from nonhost Amaranthus gangeticus, Name: 9-Hydroxy-6-phenyl-8H-[1,3]dioxolo[4,5-g]chromen-8-one, the publication is Journal of Pesticide Science (Tokyo, Japan) (2004), 29(1), 6-14, database is CAplus.

On the screening of 200 nonhost plants, an Amaranthus gangeticus extract was found to attract and subsequently inhibit the motility of Aphanomyces cochlioides zoospores. The attractant was identified as N-trans-feruloyl-4-O-methyldopamine (I) and the motility inhibitor as nicotinamide (II) using bioassay-guided fractionation and spectroscopic methods. Also isolated were cochliophilin A and chondrillasterol 3-O-β-D-glucopyranoside. I had no inhibitory effect on zoospore motility whereas II immediately halted the motility and caused encystment in a dose-dependent manner (MIC, 5 × 10^-8 M). The cystospores produced by II regenerated zoospores instead of germinating. Concomitant application of I and II produced cystospores that germinated to give hyphae. TLC examinations revealed that A. gangeticus seedling exuded sufficient amounts of II from the roots. Exudation of II from A. gangeticus might be involved in its resistance against the soilborne oomycete phytopathogen A. cochlioides.
