One of the latest reports in this area described the biotransformation of citronellol by the plant pathogenic fungus Glomerella cingulata to 3,7-dimethyl-l,6,7-octanetriol [47]. 

Finally, a Japanese group also studied the biotransformation of Z- and -nerolidol [137,138] with the plant pathogenic fungus Glomerella cingulata. Both Z- and -nerolidol were mainly oxidised at the remote double bond. Z-Nerolidol (162) was transformed into (Z)-3,7,11-trimethyl-l,6-dodecadiene-3,10,11-triol (164) while -nerolidoI (158) was mainly oxidised to ( )-3,7,11-trimethyl-l,6-dodecadiene-3,ll-diol (171) only small amounts of ( )-3,7,11-trimethyl-l,6-dodecadiene-3,10,11-triol (160) were obtained, Fig. (34). 

Several trehalase inhibitors have been isolated from natural sources these include deoxynojirimycin, validamycins, validoxylamines, salbastatin, calystigin B4, and trehazolin, the last one being the most potent. Trehazolin is used to control blight sheath of rice, caused by the plant pathogenic fungus Rhizoctonia solani, and it thus has potential fungicidal activity.12 15...

EE-Protected D-lactaldehyde 954 is an efficient chiral source for the asymmetric center of (+ )-diplodialide A (960), a metabolite isolated from the culture filtrate of the plant pathogenic fUngus Diplodia pinea [253] (Scheme 130). The carbon skeleton is assembled through two olefination reactions, the first a Wittig reaction of 954 with phosphorane 955 to give the Z...

In the case of the plant pathogenic fungus, A. glauca (-)-carvone (93 ) was metabolized to give the diol 10 hydroxy (+) neodihydrocarveol (107a ) (Nishimura et al., 1983b). 

A. niger TB JYN-2 (Noma, 2000). Furthermore, (-)-3-isothujone (28b) prepared from Armoise oil was biotransformed by plant pathogenic fungus B. allii IFO 9430 to give 4-hydroxythujone (30) and 4,6-dihydroxythujone (31) (Miyazawa et ah, 1992a) (Figure 19.133).

The biotransformation of nootkatone (2) was examined by the plant pathogenic fungus B. dothidea separated from the fungus that infected the peach. (+)-Nootkatone (2) was cultivated with B. dothidea (Peach PP8402) for 14 days to afford nootkatone diols (6 and 7) (54.2%) and 7a-hydroxynootkatone (16) (20.9%). Ratio of compounds 6 and 7 was determined as 3 2 by HPLC analysis of the thiocarbonates (12,13) (Noma et al., 2001b). Nootkatone (2) was administered into rabbits to give the same diols (6,7) (Asakawa et al., 1986 Ishida, 2005). 

P-Selinene (138) is ubiquitous sesquiterpene hydrocarbon of seed oil from many species of Apiaceae family, for example, Cryptotaenia canadensis vai. japonica, which is widely used as vegetable for Japanese soup. p-Selinene was biotransformed by plant pathogenic fungus G. cingulata...
