Rhizosphere microorganisms, suppression

I. PRODUCTION OF ANTIBIOTICS. The production of secondary metabolites with antimicrobial properties has long been recognized as an important factor in disease suppression (see Chap. 7). Metabolites with biocontrol properties have been isolated from a large number of rhizosphere microorganisms, including the fluorescent pseudomonads (Table 2). Further discussion is not given here since this is the subject of recent reviews (122,123). 

Suppression of Fusarium Wilt of Adzukibean by Rhizosphere Microorganisms... 

Microorganisms associated with the roots of certain plants may produce or facilitate release of phytotoxins. For example, microbes in the rhizosphere of chamise (Adenostoma fasciculatum H. A.) appear to contribute to suppression of herbs near these shrubs (21), a phenomenon previously attributed to toxins washed from the chamise foliage (22, 23). Similarly, hydrogen cyanide, a potent phytotoxin,...
