Resolving the Phoma enigma.
The Didymellaceae was established in 2009 to accommodate Ascochyta, Didymella and Phoma, as well as several related phoma-like genera. The family contains numerous plant pathogenic, saprobic and endophytic species associated with a wide range of hosts. Ascochyta and Phoma are morphologically difficult to distinguish, and species from both genera have in the past been linked to Didymella sexual ...
متن کاملA new phytotoxic nonenolide from Phoma herbarum.
Reinvestigation of the fermentation broth and mycelium of the fungus Phoma herbarum led to the isolation of a new phytotoxic nonenolide, namely, (7R,9R)-7-hydroxy-9-propyl-5-nonen-9-olide, which was designated with the trivial name herbarumin III (3). The known compounds herbarumins I (1) and II (2) were also obtained. The structure of 3 was elucidated by spectroscopic methods and molecular mod...
متن کاملAcidovorax radicis sp. nov., a wheat-root-colonizing bacterium.
Strain N35(T) was isolated from surface-sterilized wheat roots and is a Gram-negative, aerobic, motile straight rod. Strain N35(T) tested oxidase-positive and catalase-negative and grew optimally at pH 7.0, 30 °C and in the absence of NaCl. 16S rRNA gene sequence analysis showed over 97 % sequence similarity to strains of the environmental species Acidovorax delafieldii, A. facilis, A. defluvii...
متن کاملMal secco disease of Citrus - Phoma tracheiphila
Mal secco disease is a vascular pathogen causing serious damage and death to the host, particularly lemon, in Citrus and related genera, in Mediterranean countries and the Black Sea region. So far, however, it is unknown in Spain, Portugal and Morocco, as well as other major Citrus-growing regions of the world. Symptoms include red strands visible in stem xylem as well as veinal chlorosis, wilt...
متن کاملPhoma glomerata as a mycoparasite of powdery mildew.
Ampelomyces and Phoma species are frequently confused with each other. Isolates previously attributed to the genus Ampelomyces were shown to be Phoma isolates through studies of their morphology and life cycle and ribosomal DNA internal transcribed spacer region 1 sequence analysis. Phoma glomerata can colonize and suppress development of powdery mildew on oak and may have utility as a mycopara...
