Interactions between dark septate endophytes, ectomycorrhizal fungi and root pathogens in vitro
2019
ABSTRACT Dark septate endophytes (DSEs) are widely distributed worldwide and can promote plant growth. Therefore, they are considered potentially important plant allies, especially in stressful environments. Previous studies have reported that DSEs cohabit roots with other microorganisms such as ectomycorrhizal (ECM), endophytic and pathogenic fungi/oomycetes. However, interactions between different DSE species have not yet been reported, and studies on the interactions between DSEs and other fungi are scarce. Using a simple and reproducible pairwise growth assay in vitro, we studied the synergistic/antagonistic interactions between eight DSEs, two ECM fungi and three root pathogens. Most o…
ChemInform Abstract: Synthesis and Antifungal Activity of New N-Isoxazolyl-2-iodobenzamides.
2010
N-Isoxazolyl-2-iodobenzamides 3 and 9, with a benodanil-like structure, were synthesized by refluxing in acetic acid the corresponding benzotriazinones 2 and 8 with potassium iodide for 1 h with the aim to ascertain if they were active as fungicides against Phytophthora citricola Saw., Botrytis cinerea Pers., Rhizoctonia sp. and Alternaria sp. Among the tested iodo derivatives, compounds 3b and 9a possess interesting activities against the aforesaid fungal strains in several cases similar to that of benodanil I taken as reference drug.
Root and Basal Stem Rot of Scotch Broom Caused by Phytophthora citricola and P. drechsleri in Italy.
2005
Scotch broom (Cytisus scoparius (L.) Link, Fabaceae), an evergreen shrub native to Europe, is cultivated as a garden plant. In 2003 and 2004, potted plants with symptoms of leaf chlorosis, defoliation, and eventual wilt and associated with root and collar rot were observed in ornamental nurseries in Sicily. As much as 10% of plants were affected in a single nursery. Two species of Phytophthora were consistently isolated alone or together from the same pot with the selective medium of Masago et al. (2). Pure cultures were obtained by single-hypha transfers and the species were identified as P. citricola Sawada (approximately 40% of isolations) and P. drechsleri Tucker (60% of isolations) on…
