Figure 5. The effects of various fungal isolates on hydrilla 3 weeks after inoculation under greenhouse conditions. Isolates FHyl8 and FHY20 are Macrophomlna nhaseolina. Isolates 621P, 236, and 224 are Fusarium roseum var. culmorum. . moniliforme var.

A similar hypothetical intermediate may occur in the formation of cyclonerodiol (51) and cyclonerotriol (52) in T. roseum and Fusarium culmorum. The incorporation of various doubly labelled MVA precursors, including [4,5- C2]MVA, were consistent with the folding of 2-trans-FFF as shown. Whereas 2-trans-FPP was efficiently incorporated, nerolidol (an alternative notional precursor) was not. 

Trichodiene (49), the last hydrocarbon intermediate in the pathway, has been isolated from T. roseum, from Fusarium spp., and also from S. atra (Table 8). Specific labelling experiments have shown it to be a precursor of trichodiol (55) and 12,13-epoxy trichothecene (73), in addition to trichothecolone (101), in T. roseum (277) it is also a precursor of isotrichodiol (53) (219) and 3-acetylvomitoxin (104) in F. culmorum (278). However, relatively little work has been done on this stage of the pathway to simple trichothecenes in Myrothecium, Stachybotrys and Trichoderma spp.
