Abstract
Ascomycete fungi isolated in Central Siberia from canker lesions of Abies sibirica Ledeb. were assigned to the genus Corinectria Gonzalez & Chaverri. Our earlier research has shown four Corinectria Siberian strains to be significantly different genetically from the known Corinectria spp. This work investigated the secondary metabolites of 23 morphologically similar Corinectria Siberian strains and their phytotoxicity. The strains were divided into two types by their morphological and cultural traits, MCT1 and MCT2. The MCT1 strains synthesized the meroterpenoids ilicicolins A and B, ilicicolin A epoxide and chlorocylindrocarpol; the MCT2 strains produced ilicicolins C, D (ascochlorin), F and ascofuranol. The phytotoxicity of the Corinectria strains showed a significant heterogeneity to Picea obovata seeds and was exhibited by 31% of the MCT1 strains and 50% of the МСТ2 strains. The more phytotoxic strains had an inhibitory effect on A. sibirica calluses. Ilicicolins C, D, and F synthesized by the MCT2 strains significantly inhibited the growth processes of both A. sibirica seedlings and Pinus sibirica Du Tour saplings.
期刊介绍:
The Journal of Plant Pathology (JPP or JPPY) is the main publication of the Italian Society of Plant Pathology (SiPAV), and publishes original contributions in the form of full-length papers, short communications, disease notes, and review articles on mycology, bacteriology, virology, phytoplasmatology, physiological plant pathology, plant-pathogeninteractions, post-harvest diseases, non-infectious diseases, and plant protection. In vivo results are required for plant protection submissions. Varietal trials for disease resistance and gene mapping are not published in the journal unless such findings are already employed in the context of strategic approaches for disease management. However, studies identifying actual genes involved in virulence are pertinent to thescope of the Journal and may be submitted. The journal highlights particularly timely or novel contributions in its Editors’ choice section, to appear at the beginning of each volume. Surveys for diseases or pathogens should be submitted as "Short communications".
