| [morphological and physiological properties of phoma tracheiphila (mal secco) (author's transl)]. | the morphological and physiological characteristics of phoma tracheiphila, the cause of "mal secco" in mediterranian lemons is discussed. the structure and the characteristics of the spore, mycelium and pigment of this fungus were investigated in liquid and solid media. the growth rate was examined in different media with different ph by dry weight determination. the growth curve of p. tracheiphila was first studied in ypg, (ph 5.6) medium in the stationary and shaking culture conditions. during ... | 1977 | 600115 |
| highly sensitive and fast detection of phoma tracheiphila by polymerase chain reaction. | a new method for the diagnosis of the plant pathogenic fungus phoma tracheiphila has been developed. the method takes advantage of the enzymatic amplification of a specific 102 bp-long target sequence of fungal dna by the polymerase chain reaction (pcr) using thermus aquaticus dna polymerase. the amplified dna was characterized by agarose-gel electrophoresis, molecular hybridization using a synthetic oligonucleotide probe and direct sequencing. the application of the new method makes possible fa ... | 1990 | 1366441 |
| biological characterization of fusapyrone and deoxyfusapyrone, two bioactive secondary metabolites of fusarium semitectum. | fusapyrone (1) and deoxyfusapyrone (2), two alpha-pyrones originally isolated from rice cultures of fusarium semitectum, were tested in several biological assays. compounds 1 and 2 showed considerable antifungal activity against several plant pathogenic and/or mycotoxigenic filamentous fungi, although they were inactive toward yeasts isolated from plants and the gram-positive bacterium bacillus megaterium in disk diffusion assays. compound 1 was consistently more active than 2. among the tested ... | 2000 | 10978211 |
| phoma saccardo: distribution, secondary metabolite production and biotechnological applications. | phoma sacc. is an ubiquitous fungus, which has been reported from plants, soil, human beings, animals, and air. some species of phoma like p. sorghina, p. herbarum, p. exigua var. exigua, p. macrostoma, p. glomerata, phoma macdonaldii, phoma tracheiphila, phoma proboscis, p. multirostrata, and phoma foveata secrete phytotoxin and anthraquinone pigments as secondary metabolites, which have great potential for the biological control of weeds, and can be exploited for the production of mycopesticid ... | 2009 | 19624254 |
