“…However, as most of the micro‐organisms are phytopathogens (Yamamoto et al . ; Siewers et al . ), the practical application of micro‐organisms to grapevine to promote anthocyanin biosynthesis in grape berry skin has not been reported.…”

Significance and Impact of the Study: In this review, we evaluate the applicability of micro-organisms in viticulture. Micro-organisms can improve grape berry quality through grapevine disease protection and grape berry quality alteration. Because the use of micro-organisms to protect grapevine from plant diseases is safer than the use of chemical fungicides, the use of biofungicides in viticulture is expected to be enhanced by the increasing consumer concern towards chemical fungicides. Micro-organisms also modify plant secondary metabolites for use as flavours, pharmaceuticals and food additives. Studies of micro-organisms that promote polyphenol, anthocyanin and aroma compound biosynthesis are in progress with an eye to improving grape berry quality. AbstractGrapevine is one of the most widely grown fruit crops in the world. At present, however, there is much concern regarding chemical pollution in viticulture due to the application of chemical fungicides and fertilizers. One viticultural practice to resolve this issue is the application of micro-organisms to grapevine as a substitute for chemicals. Some micro-organisms act as an enhancer of grape berry quality as well as a suppresser of disease in grapevine through their antagonistic ability and/or systemic resistance inducing ability. Herein, we review current and prospective applications of micro-organisms in viticulture.

“…C. rosicola converted FDP to ABA (Bennett et al, 1984), and C. rosicola and C. cruenta metabolized 2Z,4E-a-ionylideneethanol (6) and 2Z,4E-c-ionylideneethanol (7), respectively, to ABA (Neill et al, 1987;Oritani et al, 1985;Kato et al, 1987). However, putative intermediates between FDP and ionylideneethanol, 4,5-didehydrofarnesol and monocyclofarnesol, were not converted to ABA, and their production by these fungi has not been confirmed (Bennett et al, 1990;Yamamoto and Oritani, 1997;Yamamoto et al, 2001). This is a shortcoming in support of the direct pathway.…”

“…Their structure elucidation was conducted as following described and H‐atom and carbon NMR values assigned ( Table ). Compound 2 was identified as (–)‐ cis ‐ γ ‐monocyclofarnesol, which, to the best of our knowledge, has never been isolated to date from natural sources whereas it was described as synthesis product . In particular, the racemic mixture (±)‐ 2 and the (+)‐ 2 enantiomer were synthesized several years ago and partially characterized.…”

[28 -30] In particular, the racemic mixture (AE)-2 [28] [29] and the (+)-2 enantiomer [30] were synthesized several years ago and partially characterized. Due to this, fully NMR assignment of compound 2 has been also reported here ( Table 1).…”

The lipophilic extracts of two marine aeolid nudibranch molluscs of the genus Spurilla collected in distinct geographical areas have been chemically analyzed. The Et O extracts of the nudibranchs were dominated by the presence of usual fatty acids and sterols and contained terpenoid compounds 1 - 3 as minor metabolites. Spurillin A (1) and spurillin B (3) were new molecules whereas cis-γ-monocyclofarnesol (2) was already reported in the literature as a synthesis product. Interestingly, bursatellin (4), previously isolated from anaspidean molluscs of the genus Bursatella, was found in the butanol extract of both Spurilla species. Compounds 1 - 4 were not detected in the extracts of the sea-anemone preys collected together with the molluscs.
