Diverse Effects of Some Bacterial Siderophores on the Uptake of Iron by Plants,e) develops. This consists primarily of bacteria and fungi (Rovira and McDougall, 1967). The predominant constituents of the bacterial flora, which may attain a concentration greater than 10 per gram of soil (Lochhead and Thexton, 1947) are members of a relatively few genera including pseudomonads,

Physical, Biological and Host Factors in Iron Competition in Soils,mith and Snyder, 1972). A factor associated with biological control appeared to be operative because the suppressiveness could be transferred to conducive soil; that is, only 600 g/m. of suppressive soil added to conducive soil in a commercial greenhouse decreased the incidence of Fusarium wilt of c

Importance of Siderophores in Microbial Interactions in the Rhizosphere,he environment. With animal pathogens, siderophore synthesis plays a direct role in the infection process (Weinberg, this book). Growth of numerous bacterial genera is stimulated by excess iron in body fluids and tissues of vertebrate hosts. Conversely, host defense mechanisms include withholding ir

Suppression of Root Diseases of Wheat by Fluorescent Pseudomonads and Mechanisms of Action,t production in the pacific Northwest of the U.S.A. Take-all occurs mainly where wheat is grown under irrigation such as the Columbia Basin and Snake River plains and in the high rainfall region of western Washington and Oregon. The take-all fungus infects the roots, crowns, and lower stems of wheat

Biological Control of Fusarium wilts by , and its Enhancement by EDDHA,e mechanism of biological control was suggested, at least in part, to be as a result of competition for iron between the pathogen and siderophores produced by .. Addition of iron to soil (as FeEDTA) nullified this biological control whereas addition of EDDHA (an Fe. chelate with high binding constan

Methods of Studying Plant Growth Stimulating Pseudomonads: Problems and Progress,d pot experiments in the Netherlands strongly suggest that potato growth stimulation by seed tuber bacterization with pseudomonads selected for efficient siderophore mediated Fe.-uptake, is most noticable in soils where frequent potato cropping causes a significant reduction in potato yield (Geels a

Emergence-Promoting Rhizobacteria: Description and Implications for Agriculture,o increase yield of sugar beet (Suslow and Schroth, 1982), radish (Kloepper and Schroth, 1978) and potato (Burr et al., 1978; Howie and Echandi, 1983; Kloepper et al., 1980). In each case, evidence of enhanced plant growth was observed sometime during the early-growth season prior to harvest. Increa
