Metarhizium robertsii. With the advent of genetic profiling, placing these fungi in proper taxa has now become possible. Introduction The filamentous ascomycete Metarhizium robertsii is an omnipresent and soil-dwelling pathogen of insects, ticks and mites [1,2]. M. guizhouense (ARSEF 7847) from Arizona was intermediate and the M. acridum isolates (ARSEF 324, 3341, and 3609) were the slowest killers. Metarhizium robertsii conidia placed on gelatin-containing agar or in liquid culture medium can only grow if they produce protei-nases to utilize gelatin as a nutritional substrate, and the expression of such proteinases is easy to measure. Noskov, Y. Unfortunately, commercialized worldwide use of fungal biocontrol agents is partially limited by the failure of co- nidia to retain viability during long-term storage, trans . Root surface and endophytic colonization of switchgrass ( Panicum virgatum) and haricot beans ( Phaseolus vulgaris) by M. robertsii were examined after inoculation with fungal conidia. Under iron-depleted culture conditions, the entomopathogenic fungus Metarhizium robertsii (Bischoff, Humber, and Rehner) (= M. anisopliae) produces a complex of extracellular siderophores including novel O-glycosylated and N-oxidized coprogen-type compounds as well as the known fungal siderophores Nα-dimethylcoprogen (NADC) and dimerumic acid (DA). • Methods : We used light and confocal microscopy .
