Colletotrichum acutatum, Agent of Anthracnose on the New Host Black Elderberry (Sambucus nigra) in Switzerland

Sambucus nigra (Elderberry) Monograph

Introduction Sambucus nigra, or European elder, is a tall tree-like shrub, native to Europe, Asia, and North Africa, and naturalized in the United States. Various parts of the elder have long been used in traditional medicine as a diaphoretic, diuretic, astringent, laxative, and emetic. The berries were used traditionally as a food to make elderberry wine and pies, and as a flavoring or dye. Cu...

Strawberry Anthracnose: Histopathology of Colletotrichum acutatum and C. fragariae.

ABSTRACT Ontogeny of the invasion process by Colletotrichum acutatum and C. fragariae was studied on petioles and stolons of the strawberry cultivar Chandler using light and electron microscopy. The invasion of host tissue by each fungal species was similar; however, each invasion event occurred more rapidly with C. fragariae than with C. acutatum. Following cuticular penetration via an appress...

Seasonal Fluctuations of Lectins in Barks of Elderberry (Sambucus nigra) and Black Locust (Robinia pseudoacacia).

Elderberry (Sambucus nigra) and black locust (Robinia pseudoacacia) agglutinins, which are abundantly present in the bark of both species, display seasonal fluctuations with regard to their content in this tissue. These seasonal changes result apparently from a circa-annual rhythm of lectin accumulation and depletion during autumn and spring, respectively. Because the bark of trees can be consi...

Anthocyanins and other polyphenolics in American elderberry (Sambucus canadensis) and European elderberry (S. nigra) cultivars.

BACKGROUND Ten genotypes representing two elderberry species, Sambucus canadensis L. (eight genotypes) and S. nigra L. (two genotypes), were examined for their anthocyanins (ACY), total phenolics (TP),°Brix, titratable acidity (TA), and pH over two growing seasons. RESULTS Overall, fruit generally had higher ACY, TP, ACY/TP,°Brix, and pH in 2005 than 2004. All samples of S. canadensis had sim...
