The aim of this project was to study changes in the content of <i>trans</i>-resveratrol in berries and leaves of grapevine (<i>Vitis</i> sp.) infested by fungal diseases, especially by <i>Botryotinia fuckeliana</i> Whetzel, called as grey mildew, <i>Plasmopara viticola</i> (Berk. & M.A. Curtis) Berl & De Toni, called downy mildew and <i>Uncinula necator</i> (Schw.) Burr, called powdery mildew. In our experiments two white and two blue varieties were used. Contents of <i>trans</i>-resveratrol were determined in healthy and infested leaves and in healthy berries. Infested leaves of white varieties contained more <i>trans</i>-resveratrol than those of blue varieties. The content of <i>trans</i>-resveratrol in berries was lower than that in leaves.

Botryotinia Fuckeliana

Greenhouse-grown Heuchera plants, treated with fenhexamid (Decree, SePRO, Carmel, IN; FRAC group 17 hydroxyanilide), with active gray mold were submitted to the Penn State Plant Disease Clinic in December 2010 from a commercial operation in north-central Pennsylvania. Genetic and phenotypic analyses identified the isolate as Botrytis cinerea Pers. (teleomorph Botryotinia fuckeliana (de Bary) Whetzel), HydR3 phenotype (2) and not B. pseudocinerea (previously Botrytis group I) (4), naturally resistant to fenhexamid (phenotype HydR1) (1). While 0.2 μg of fenhexamid per ml or less is required to slow mycelial growth and germ tube elongation of sensitive isolates by 50% (EC50), the radial growth EC50 of the Heuchera isolate was approximately 2,000 μg of fenhexamid per ml in culture. Five cucumber seedlings receiving 25 μl of 0.1 M dextrose containing the label rate of Decree (1,800 μg/ml) on the growing tip were inoculated with colonized agar in the drop. Five check plants received 25 μl of 0.1 M dextrose. B. cinerea from silica gel storage since 1988 was also tested. This experiment was repeated three times. The 1988 isolate killed all fungicide-free but no fenhexamid-treated plants. The Heuchera isolate killed all fungicide-free and fenhexamid-treated plants within 4 days. To our knowledge, this is the first report of B. cinerea from a greenhouse in North America with fenhexamid resistance. Resistance occurs in U.S. fields (3). The Heuchera isolate's HydR3 resistance phenotype (2) has been detected in Germany, Japan, and France and has mutations affecting the 3-keto reductase protein, encoded by the erg27 gene, the specific target of fenhexamid and involved in Botrytis sterol biosynthesis. The Decree label states that it is to be used only twice on a crop before switching to a different mode of action. Greenhouses have resident Botrytis populations that are likely to be exposed to any fungicide applied in the structure. Growers should consider using fenhexamid only twice in a particular greenhouse, rather than on a particular crop, before switching to a different mode of action. References: (1) P. Leroux et al.

Botryotinia Fuckeliana

Botryotinia fuckeliana (de Bary) Whetzel (syn. Botrytis cinerea Pers.:Fr.) causes gray mold on the foliage of a large range of horticultural and agricultural crops, including potato (Solanum tuberosum L.). This weak pathogen may also produce pit rots on potato tubers (1). In April 1999, two lots of seed potatoes produced in Scotland were found to contain a significant number of tubers with soft rots. The cultivars were Maritiema and Charlotte, with 2.2 and 0.5% of rotted tubers, respectively. The rots on tubers of cv. Maritiema were all soft, wet, and extensive, with a distinct edge, but the proportion of this type of rot was much lower (approximately 30%) on the cv. Charlotte tubers. Gray sporangiophores developed around tuber eyes. When the tubers were cut, the affected tissue was peach to pink-gray in color but darkened on exposure to air, and was soft and water-soaked in appearance with a pale brown or, occasionally, yellow margin. A faint vinegary odor could be detected occasionally. B. fuckeliana was isolated on potato dextrose agar (PDA) from all 15 tubers of cv. Maritiema and from the three (out of 13) tubers of cv. Charlotte that had large, soft rots. Tubers produced at Scottish Agricultural Science Agency's Gogarbank farm near Edinburgh in 1998 were used for confirmatory pathogenicity tests conducted in late April and May 1999. Using a cork borer, a wound 5 mm in diameter and 5 mm deep was made in each tuber and 5-mm-diameter agar plug from either the edge of a colony of B. fuckeliana or of PDA was inserted into the wound. Nine tubers of cvs. Maritiema and Charlotte were inoculated for each treatment and tubers incubated at 5°C in boxes lined with moist filter paper. Rots, similar to those on the commercial seed tubers, developed after 28 days at wound sites inoculated with B. fuckeliana. The fungus was isolated by placing a small piece of rotted tissue from each rot on PDA. B. fuckeliana was recovered from all rots. The mean width of rots was 51 mm for cv. Maritiema compared with 40 mm for cv. Charlotte. Depth of rots was similar for both varieties. Lesions did not develop at wound sites inoculated with PDA agar only. In a second experiment, tubers of cv. Maritiema were inoculated with B. fuckeliana as described above and incubated at 5°C or room temperature (15 to 18°C). There were nine tubers for each temperature. After 21 days, no lesions had developed on tubers incubated at room temperature, but large, soft rots were present on those incubated at 5°C. The lesions produced by B. fuckeliana in these experiments were relatively large compared with the 5-m-deep rots reported previously (1) after 60 days of incubation. The appearance of these rots is similar to that for other diseases, e.g., pink rot and watery wound rot, and infections by this fungus may have been incorrectly diagnosed in the past. Moreover, the development of such rots may be favored by the recent increase in the use of low temperature storage for seed potatoes. Reference: (1) H. W. Platt. Can. J. Plant. Pathol. 16:341, 1994.

The occurrence and content of some polyphenols and the antioxidant activity of compounds present in grape berries, stems and leaves of <i>Vitis vinifera</i> L. were evaluated. Three white and three blue varieties of grapevine were investigated. The contents were determined of <i>trans</i>-resveratrol, <i>trans</i>-piceid, caftaric acid, tryptophan, catechin, epicatechin, total polyphenols, and flavanols, both in healthy material and in the samples of the plant material infested with microorganisms (<i>Botryotinia fuckeliana</i> Whetzel anamorph <i>Botrytis cinerea</i> Pers.; Uncinula necator (Schw.) Burr; <i>Plasmopara viticola</i> (Berk. & M.A. Curtis) Berl & De Toni). The antioxidant activity of the extracts obtained was determined by different methods: FRAP (Ferric Reducing Antioxidant Power), DPPH (2,2-diphenyl-1-picrylhydrazyl radical) and TAC-PCL (Total Antioxidant Capacity of Photochemiluminescence). The content of <i>trans</i>-resveratrol varied between 0.3–2.3 mg/kg and 0.7–12.1 mg/kg in non-infested and infested grape berries, respectively. The content of <i>trans</i>-piceid between 0.6–2.9 mg/kg and 1.5–6.3 mg/kg in non-infested and infested grape berries, respectively. The content of trans-resveratrol varied between 2.5–10.3 mg/kg and 3.7–20.9 mg/kg in healthy and in infected leaves, respectively. The content <i>trans</i>-piceid varied between 11.3–58.4 mg/kg and 18.5–60.9 mg/kg in the healthy and in the infected leaves, respectively. The highest content of trans-resveratrol was found in stems (16.3–276.3 mg/kg). In young lateral shoots, the highest levels of <i>trans</i>-piceid (12.6–99.7 mg/kg) and caftaric acid (474–2257 mg/kg) were determined. The infested grape berries showed a higher antioxidant activity, which was most closely correlated with the content of total polyphenols (correlation coefficient = 0.8336–0.9952).
