    Approximately 600 Actinomycete strains were isolated from soil samples collected from forests in Korea. The isolates were assessed for their herbicidal activities, and KRA14-329 was found to have strong herbicidal activity. Based on 16S rRNA gene sequence analysis and morphological characteristics, KRA14-329 was confirmed to be Streptomyces sp. NMR and ESI-MS analyses of the Streptomyces identified cyclohexamide compounds, 329-M1 and 329-M2, which contained glutarimide moiety in their structures. This study was conducted to determine characteristics and mode of action of these two active herbicidal compounds isolated from KRA14-329. To evaluate herbicidal activity of the isolates, 329-M1 and 329-M2 were applied at 62.5, 125, 500 μg mL-1 as a foliar application to fourgrass species, Sorghum bicolor, Echinochloa crus-galli, Agropyron smithii, and Digitaria sanguinalis; and four broadleaf species, Solanum nigrum, Aeschynomene indica, Xanthium strumarium, and Calystegia japonica. Application of 329-M2 at 125 μg mL-1 pr ... 전체 초록 보기
