摘要:

Homogeneous endo-polygalacturonases (PGs) fromAspergillus nigerandFusarium moniliformewere used to prepare rabbit antisera. IgG were purified from antisera by Protein A-sepharose chromatography. Purified IgG were tested against endopolygalacturonases fromSclerotium rolfsii, Sclerotinia sclerotiorum, Rhizoctonia solani, Rhizoctonia fragariaeandFusarium oxysporum. Double immunodiffusion tests, ELISA tests and Western blottings showed that all the enzymes react with both antisera suggesting that a basic PG structure is mantained among the different fungi.

摘要:

Several 7-chloro-imidazo(1,2-c)pyrimidines were tested on tobacco callus cultures in order to verify a possible cytokinin and anticytokinin-like activity. These compounds were used alone and in combination with kinetin or zeatin.

摘要:

Six species ofScrophulariaceaewere examined for their content in iridoid glucosides. The results, together with data from literature, are used for a classification of the family based on the presence and nature of iridoid glycosides. With regards to iridoids,Scrophulariaceaecan be divided into three main groups.

摘要:

Previously known only from two localities in north-eastern Italy (Provinces of Bolzano and of Sondrio),Amblystegium compactum(C. Muell.) Aust. (Musci) has been collected recently at Isola Madre (Lago Maggiore, Province of Novara). Its special ecology and its origin in Europe are briefly discussed.

摘要:

First record of Cylindrotheca fusiformis var. fusiformis Reimann et Lewin in the Mediterranean Sea. - The Authors report the presence of the pennate diatomCylindrotheca fusiformisvar.fusiformisin the coastal plankton off the coast of the Romagna region of central Italy where it frequently gives rise to phytoplankton blooms. The Authors give some information on the morphology of the species using both light and electron microscopy.

摘要:

The authors examined the influence of external phosphate variation on metabolic aspects of four strains ofAnabaenaspp., isolated from the phytoplankton of 4 lakes in southern Italy. The dry weight of the algal cultures, nitrogenase and phosphatase activity, total intracellular phosphorus, chlorophyllaand total proteins were measured.
